The world is advancing greatly these days, especially the environmental parameters. All these parameters demand timely monitoring so as to obtain the performance of these parameters. Since many years, most of the researchers are really striving hard to develop technology and instruments to monitor these parameters. All these instruments and devices provide approximate values but to obtain accurate values, it is important to have special kind of tools to monitor these parameters. Monitoring water related parameters are even a bigger challenge because the flow of water is very harsh at times and even the water in rivers and oceans get rough and aggressive.

It has become a necessity to measure and monitor all the environmental data through a wireless technique because reaching at a particular spot for monitoring can be cumbersome. Paying a physical visit to collect water traditionally from a site can be a difficult task. That is why; these days, technology has given an opportunity of monitoring environmental data at real-time that too wirelessly. Moreover, conventional lake monitoring and oceanographic systems may undergo some damages or breakdown due to traffic of boats or even debris. But to tackle all these challenges, researchers have developed a permanent solution to cater to such needs that too in association with the Intelligent Rivers Project.

Be it any kind of weather, harsh climatic conditions or aggressive river movements, the innovative buoy system supports real-time capturing of water and transmitting its quality data even while on long distances. The buoy has greater capacity of withstanding any kind of abuses from floating debris and even boat traffic. The design of buoy somewhat resembles a common marker buoy which makes it sure that the attention of users who curiously access river will also not be withdrawn. To access the buoy, special kind of tool is required to access the inner compartment of the buoy which is not possible as its design is tamperproof. The buoy is in-built with rechargeable lead-acid batteries which can be recharged if the battery drains out completely. The batteries can be charged even on-board and the battery lasts for nearly a month and sometimes even more.

Some of the major applications of buoy are mostly found in monitoring of rivers and to capture sensors from lakes and stream because of its capability of floating in water and withstanding any harsh weather or sea conditions. It can be easily installed in water or in rivers with the help of anchors and fasten it to obtain the real-time data. Some of the benefits of using buoy are it is very cost-effective, it is a system which is wireless and is real-time transmission of data, and lastly, its extended usage or usage while being on long distances. It has great durability in even fast flowing waters. Most of the oceanographic researchers have widely adopted installing and using buoy because of its unique capabilities and benefits.

A lot has been done for saving electricity and other resources but Smart Meters has set a milestone in managing the electricity. Now with these modernized meters; the electricity bill is under your control. They have been accepted by many countries to save electricity and manage it. With time many new meters are coming up with smart technology to make it more efficient and reliable. For better control on the distribution and automation on the power supply; these meters are fitted with advanced distribution automation programs

A smart meter is an electricity meter which reads the consumption of electricity in the similar manner as a normal meter but has the capability of two way communication between the meter and the centralized system. It can also be monitored remotely to change the mode of payment or for tariff -information. An in home display is also provided with these meters which display the information to the consumer about the amount of consumption of electricity in units as well as pounds. With the implementation of these smart meters, people will know about the operation of power industry and how they consume energy.

This advanced technology has not only helped the country or the power grid to save and manage energy but they have been a huge success with the benefits it provides to the consumers. People will have the benefit of having access to up to date information about the tariffs, real time usage of electricity in units as well as in amount. Consumers can manage their budgets properly by saving electricity and money. This technology also helps in getting accurate bills as the manual meter reading will be replaced. This automotive distribution technique will help in accurate distribution of energy and efficient management and generation of power supply. Smart metering is cost effective and helps in more use of low carbon generation power. One can easily switch the energy suppliers with the data the consumers are accessible to. The meter is designed in such a manner that it is suitable to all energy suppliers.

Implementing such a change in the society is not an easy task, a lot of planning and studies are still going to make this more effective and to integrate these smart meters installations and distribution automation programs. By end of 2020, this technique will make a remarkable change in the power industry and will cover up most of the homes. A lot of articles and writings are floating on the internet to educate and create awareness among people for the advantage and benefits of smart metering and how to reduce the consumption of electricity and less carbon emission. Different slots are allotted as off peak, mid peak and on peak where the rates of the energy consumption are different. Consumers can use the electricity during off peak hours and save electricity and in turn money also.

This effective technique will not only save electricity but will help people to do a lot for the environment. Smart metering has been widely accepted by the consumers with the number of advantages they get, and it has also marked a great change in the mindset of people in using and saving energy. These smart techniques are said to be launched soon on gas and water supply.

Smart meters have been accepted with open arms by the consumers. These are electric meters that read the electricity usage in the same manner as the normal meters but have the ability of two way communication from the meter to the centralized power grid. This has the advantage to the utilities to update the tariff information remotely. Smart metering has helped in efficient management and distribution of electricity. With more and more countries adopting this technique, a lot has been done to make it more reliable and undeviating. There has been a lot of discussion on whether these meters are beneficial to the customers or not than the conventional meters. Let’s discuss the advantage of these smart meters to the consumers, utilities and the environment.

• The first and foremost advantage is to control the electricity bill and usage of electricity. With the help of smart meters consumers can consume energy during off peak hours when the rates are minimal; this will help in saving your money as well as energy.
• With Smart meters, consumers have the benefit of having access to up to date information about the usage of electricity in units as well as in amounts as these meters comes with an in home display. One can manage their monthly budget in a proper manner and reduce their power bills.
• Consumers get detailed information on how the power industry operates.
• With full access about the tariffs and other information, consumers can easily switch the electricity suppliers.
• This technique is an efficient mean to make the consumers aware for reducing their usage of energy and saving power.
• Accurate electricity bills are assured with Smart meters.
• Consumers are protected from the unnecessary sales techniques to sell additional products by the company salesman while installing the new meters.

These smart meters are not only beneficial to the consumers but are also a great boon to the electricity suppliers as the companies can change the tariff information remotely. Removal of manual meters helps in monitoring the system more quickly and efficiently. Smart meters allows more control on the distribution of electricity with the real time data that they provide with the help of this technique, thus enabling them to reduce power cuts or black outs. The companies also get the benefits of optimizing their income as a consumer can change the supplier without changing the meter. These smart meters are designed to suit all electricity suppliers.

Smart meters are also beneficial for the environment as a lot of energy is saved with the help of this application. With more people getting an insight in the consumption of energy, they have become more conscious in making efforts to reduce the usage of energy and less carbon emission. It reduces pollution and helps in making a better and a greener environment.

Smart meters have been therefore widely accepted by many countries and it is estimated that by 2020, it will be installed in most of the houses which in turn will help in managing the electricity and power grid more efficiently.

With the so many Companies manufacturing smarter products today, there are now Companies, which have come up with solutions enabling people to cut down on their heat consumption costs. One such Company is Itron, which has recently come up with its state of the art product for measuring heat energy costs more accurately. This device is proving to be a revolution in managing, calculating, and thus allocating rightly the energy produced by thermal generators, and used by consumers. Itron, with this new 'thermal energy' measuring product, anticipated the pulse of the market, and the growing need for products like the one just launched. And as a smart move, in order to suffice the requirements of the general consumers, it introduced its revolutionary product 'EquiScan', just at the right time, before anybody could think of manufacturing the same.

At most societies and multi-housing apartments, thermal energy happens to be the primary source for heat. Most of the times it so happens that while billing the consumers, it becomes a challenge to accurately calculate the amount of energy which has been used by a consumer, so it becomes all the more difficult to decide on what to be charged (billed) to the customer.

To stop this racing problem, and to inculcate the practice of 'fair billing', this all new product EquiScan has been introduced as an 'eye opener', for all those using thermal energy for their regular household or commercial work.

Another very significant role of EquiScan having been seen to be played apart from rightly measuring and billing the customers for the amount of thermal energy used is that this device is actually helping the residents of various residential apartments and commercial holding, to inculcate in themselves a habit of saving energy, using the same more consciously.

Moreover, owing to its simplistic design, this marvel device is extremely simple to use and operate. Essentially, being a 'Plug-and-play' device, EquiScan consists of various components like 'heat cost allocators', master radio units’, ‘water meter communication modules', 'master radio units', and an 'application software'. Further, with an easy installation procedure, this device is also extremely cost effective to be maintained.

As a consumer I have been using the product and have found it to be extremely useful and efficient. It has enabled me to majorly cut down on my consumption of thermal energy since the time I have starting using it, and has also probed me to become more conscious about using this natural resource called 'heat', more carefully that I used to do earlier.

If you are also much dependent on 'thermal energy', for carrying your regular house hold works and commercial activities, then I would advise you to use EquiScan, and give it a try at least once. The results are apparent!

Telemetry refers to a highly advanced and automated communication system where measurements are made and data collected without a person having to be present physically. In simple words this system can help you take measurements of various elements, processes and activities without any human contact. Businesses are fast employing this technology as it is helping them increase their productivity. Law enforcement agencies, meteorological agencies, disaster management agencies etc. are among the primary users of this technology. Today this technology has been further advanced with the data being transmitted wirelessly across large distances. Let us now discuss some of the advantages of wireless telemetry systems

• Real-time Data Collection

Wireless telemetry systems allow us to measure and collect data at remote or inaccessible points and this data can be transmitted easily over large distances in real time. The advantage of being able to look into events and processes as they happen are innumerable. Apart from monitoring the events as they happen this also allows us to exercise more control over the outcome of the event or the process.

• Reduces Operational Costs

One of the biggest advantages of using this system is that it helps you in reducing operational costs. Since the data is collected and transmitted automatically from faraway locations there is reduced requirements of human resource have to collect the data manually. This can help any organization cut operational costs substantially.

• Reduces Risks On Human Life

There are occasions where people have to work in highly dangerous situations. This might involve monitoring an active volcano or keeping track of a tornado. Wireless telemetry systems don’t require a person to be physically present and take a risk on his/her life. All the data that needs to be collected can be done from the comfort of a lab hundreds of miles away.

• Prevents Natural Disasters

Wireless telemetry systems are finding extensive usage in disaster management. For example this system can be used to measure the rising level of water in a river for flood control or measure the speed of wind on high sea barges. Fed with such information in real time can help reduce the impact of natural calamities if not prevent them.

• Collects Data From Moving Objects

This technology can be used to collect data from objects that are in constant motion. For instance this technology can be applied to pin point the exact location of a train over a large railway network or measure its speed at any instant.

• Data Sharing

Since the data collected us transmitted wirelessly this also gives us the scope of sharing this data. For instance information regarding an imminent flood like situation can be shared between different entities such as the government, disaster management agencies, healthcare; transportation etc. that can help tackles such situations in a much smoother way.

These are some of the popular advantages of wireless telemetry systems. Since this system is finding its usage across a number of businesses and agencies one can easily argue that there are many other advantages associated with this system.

Flowmeters find extensive usage in different industries. They are used to measure the flow rate of fluids which can either be in the liquid or gaseous state. One of the technologies that has found acceptance across the board is the use of the ultrasonic flowmeter. Such flowmeters give much more accurate data over the traditional flowmeters. Today with the advancement of the digital signalling has been powering these meters that allow industries to keep a tab on the exact flow of liquid or gas in a pipeline. Small and large businesses are fast adopting this as a preferred means of measuring the flow of liquid.

Doppler flowmeters and Transit Time flowmeters are two distinct types of instruments that are being used in the industry. Often we tend to confuse one for the other as both these instruments make use of the ultrasonic technology to measure the flow of liquid. There are however many difference in the way these flowmeters work and here we shall take note of the differences between Doppler flowmeters and Transit Time flowmeters. To understand the differences between the two we need it is important that we understand their working mechanism.

The mechanism of this type of flowmeters is based on bouncing signals which was proposed by Christian Doppler in what is famously known as Doppler Effect. The theory is that the frequency shift is in direct proportion to the velocity of the liquid. Here the signals bounce off small particles or bubble in the moving fluid in a pipe and create what is popularly known as the 'Doppler Shift'. This is turn creates what we know as return signal frequency. Here the flowmeter measures the Doppler Shift and then it calculates resulting speed of the reflective particles. This is further multiplied by the internal diameter of the pipe through which the liquid passes to produce volumetric flow.

However this kind of flowmeters has a have disadvantage as they are don't work with liquids that don't have enough sonically reflective particles in your flow stream. While those who promote this technology criticise this argument the fact remains that if there is no reflective particle in the liquid for the signal to bounce from there is no way that it will offer you accurate results on the flow of the liquid.

Transit-Time flowmeters also makes use of the ultrasonic technology. These work by measuring the time taken by an ultrasonic signal transmitted from one sensor, to cross a pipe where the liquid is flowing and be received by a second sensor. Here two different components namely the upstream and downstream time measurements are compared. This difference in time (Transit-Time) is calculated using a bunch of powerful algorithms to produce an accurate flow velocity. If there is no flow the transit time would be equal in both directions. When there is flow of liquid the sound travels faster in the direction of flow and slower in the direction of flow. This technology is more reliable and less expensive compared to Doppler flowmeters.

The downside of this measurement technique is the fact that the fluid should be clean and should not contain any bubble or solid particle as this will result in the higher frequency sound being attenuated and making them too weak to transverse the pipe.

You can clearly make out from the above working mechanism that both these technologies are effective in measuring the flow of liquid. However industries must make a choice based on the type of liquid that they are going to measure as both these systems have their own disadvantages.

By definition Flowmeter is an instrument that is used for measuring linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. It is extensive used in the oil and natural gas based industries where the flow gas and liquid needs to be measured accurately. Technology has come a long way since the days of the initial flowemeters and there are many different ways in which the flow of liquid can be measured. There are a number of technologies such as differential-pressure, turbine and positive-displacement that are being used to measure the flow of gas and liquid. Some of these technologies are far ahead of the others in terms of their application in the industry. Here in this short write-up we shall take a look at four flowmeter applications that you must watch out.

1. Multiphase Flowmeters - In the oil and gas industry fluids are known to be different states of matter i.e. liquid, gas and steam. While most traditional flowmeters are known to measure a single type of flow liquid, gas or steam we are seeing extensive usage of multiphase meters in the oil and gas industry. When the oil comes out of the well it is a mixture of all these components and it serves as a great advantage to the business to measure the fluid before the different components are separated using a separator in the wellhead. They can serve in a variety of functions in the industry such as well testing, custody transfer, and allocation metering.

The downside for these multiphase meters remains their prices as they are highly expensive and not within the budget of small businesses. In fact many wells cannot justify the expenditure behind multiphase flowmeters due to their production limit. In terms of technology these multiphase meters are way ahead of traditional technologies that are being used and in years to come they might find their way into the small oil and gas industries.

2. Delivery Network - Delivery of the fuel through the distribution chains is an important part of the petroleum industry. Here fuel is loaded into truck and delivered to homes, businesses, transport industry such as airplanes, ships etc. Here again there is immense competition among technologies. Traditionally this market belonged to positive-displacement flowmeters however Coriolis flowmeters are fast becoming the preferred technology for most businesses. With approvals from various industry bodies such as the American Petroleum Institute is making fast inroads into the market. One of the biggest advantages of this kind of flowmeter is the fact that it can be applied in a small ecosystem where other technologies don’t make a sound financial decision. These include district energy metering, residential metering, boiler inlet measurement, steam flow measurement, flare gas measurement, and open channel measurement among others.
3. Custody Transfer of Natural Gas – One of the areas of great importance in the natural gas industry is custody transfer. Natural gas goes through a series of transitions and till it reaches the customers. On many occasions the ownership of the gas is transferred from one company to another till it reaches the consumers. Thus flowmeter play an active role during the custody transfer. Like in the case of delivery network traditionally differential-pressure or turbine flowmeters were used for this purpose. But over the last decade and half ultrasonic flowmeters are being used for custody transfers having received necessary approvals from the American Gas Association (AGA). There is however a downside to the ultrasonic flowmeters as they have to be calibrated on a regular basis. This involves sending the flowmeter to a calibration facility. This requires a business to in place for their ultrasonic meters. Also sending the meters for calibration from faraway distances is both expensive and time consuming.
4. Stack Gas Measurement - With the growing voice for environment protection and the influence of the Environmental Protection Association (EPA) the need stack flow measurement accelerated has accelerated. The advantage with this flowmeter technique is the fact that it can be used for continuous emissions monitoring (CEM). Thermal flowmeter suppliers have developed multipoint flowmeters which are used to measure flow at as many as 16 points in the stack which results in higher levels of accuracy compared to single-point thermal flowmeters. Apart from this differential-pressure and ultrasonic flowmeters also being used stack gas measurement. While the differential-pressure flowmeters use averaging Pitot to measure the flow ultrasonic flowmeters measure it by sending a signal back and forth across a pipe allowing them to cover large diameters pipes.

There are a low of development that are taking place in the world of flowmeters to make them efficient as well as make their usage diverse. In the coming years we might see newer technologies and applications making their way into the market.

Flow meters are used in different industries, such as aerospace, petrochemical, mining and agriculture. These meters are use to measure the rate of volumetric flow or mass of a liquid or gas. There are many different types of flow meter available and easy model is designed with a specific application in mind. Hence, it is imperative to choose the right flow meter. If you are looking to measure the mass or volumetric flow of a liquid or gas, you should opt for an ultrasonic flow meter rather than a mechanical flow meter.

It is imperative that you choose the right flow meter for your industrial applications and this means having a thorough understanding of the use and working of flow meters. You would have to take into consideration calibration, maintenance, available of spare parts as well as cost of installing the meter before you zero onto one. This is where ultrasonic flow meters come in. They are designed to be cost-effective and do not have any moving parts. As a result, these meters are virtually maintenance-free. However, before you opt for an ultrasonic flow meter, there are certain points that you should take into consideration, since this meter can be used for a variety of applications.

Ascertain the size of the pipe, the minimal and optimal method, temperature pressure, the amount of particulate matter in the liquid or gas and what demands are put on the analog result are some of the points to consider before choosing the right ultrasonic flow meter, also referred to as non-intrusive Doppler flow meter.

Thankfully, you can get ultrasonic flow meters that are can be used for sealed piping and usually these are portable meters. Then there are ultrasonic flow meters that can used for cleanser liquid or one that can be used in applications where there are 100 PPM of 100 microns of particulate matter in the liquid or gas.

Doppler flow meters are ideal for wastewater programs, as they help to keep the pressure low. When low pressured is maintained, there is no need for maintenance. If you are using an ultrasonic flow meter in applications with clean liquids, you can expect a little bit of aeration. Nonetheless, Doppler flow meters are very effective, accurate and cost-effective. They can be used in any industry that is looking for a reasonably priced ultrasonic flow meter. You also can look to hire an ultrasonic flow meter which has its own advantages, such as getting a professional at your site to provide training to your plant employees and leaving the maintenance, if any, to the leasing company.

An ultrasonic flow meter not only allows you to reduce your operating costs, it also helps you stay within your budget and operate your plant in a more efficient manner. That is why it is important to choose the right ultrasonic flow meter for your industrial application. Take into consideration the different factors involved during the working of the meters and this will help you make the right choice. When you choose the right Doppler flow meter, you will have the perfect device for measurements that may be crucial to your application.

The existing trend stands witness to numerous homes in the U.S. the UK and Canada switching over to smart meters. The change is taking place to give homeowners control over how they spend money on their energy. For instance, in the traditional meters, homeowners were charged by the month based on the energy they consumed during that period. When a house owner switches to a smart meter, he is charged by the hour.

It is claimed that a smart meter can help consumers save money during peak hours by allowing them to reduce their energy consumption. However, this is only possible if consumers become energy conscious and follows a restrictive plan to limit their energy usage during peak hours. This can be difficult and tough. You also have the option of forgetting about a smart meter and working with your electrical provider to reduce your energy costs, but more often than not, providers have highly restrictive contracts, which can be cumbersome.

The good news is you can save money when you use a smart meter. With a little bit of foresight and ingenuity you can make your home more energy efficient. Here are some tips to cut your energy costs with a smart meter.

The U.S. Department of Energy states that heating and cooling forms about 54 percent of an average American household’s energy costs. If you adopt a smart meter, this is one cost you definitely would like to reduce. During the warm summer months, you should set the thermostat at a standard 77-degree Fahrenheit and ensure you switch off the air conditioner when you are leaving home. During peak hours, try using a fan to cool yourself down instead of using air conditioning.

The ideal way to save money on heating is to set the water heater at a lower temperature and lower the thermostat at nights. You also have the option of switching to a more energy efficient heating system by going into for a Energy Star rated boiler. Although an expensive investment, this will save you a lot of money in the long run.

Opt for kitchen appliance that are Energy Star rated. These appliances will use up to 54 percent less energy compared to your older appliances, according to Washington Post. In fact, if you opt for a refrigerator that has an Energy Star label you could end up saving as much as $100 a month on your electricity bill.

There are many other ways to save money on energy in your kitchen. Some of them are highlighted below:

• Use pans and pots that fit precisely over the burner. If your pans and pots are too small, it is a waste of heat
• Try and use a dishwasher to wash dishes, as most dishwashers are designed to save water. You also can use the "Economy" mode on the dishwasher to save even more water.
• If you have a trash compactor, use it at nights once in for all rather than using it several times during the day.

If you have incandescent light bulbs in your house, your home is not energy efficient. So switch to CFL light bulbs, which not only use 75 percent less energy compared to incandescent light bulbs, but also tend to last much longer.

These are some of the ways you can cut your energy costs with a smart meter and enjoy savings. These simple but valuable tips will not restrict your daily life and you will not have to schedule a tight daily power usage.

What is a magnetic flow meter, and how it works?

As the name suggest it is a measuring instrument, used for determining the flow of any liquid in a pipe. Since, it is based on the Law of Electromagnetic Induction as incepted by Faraday; it is referred to as Magnetic or Mag Flow Meter. It generates a magnetic field and channels it into the liquid flowing through the pipe.

The flow of liquid creates voltage signals that are sensible for the electrodes integrated on the tube walls. When the flow of conductive liquid increases, it will instantly result in greater voltage, which also justifies the Faraday's law that says generated voltage is directly proportional to the speed of flowing liquid. Then there is an electronic transmitter also, which is integrated with the instrument to process the voltage signals for determination of liquid flow in a quantitative manner.

One can easily measure the velocity of any fluidic substance like water, caustic, slurries, acids etc by using Magnetic flow meter. However it should be a conductive liquid having electric conductive of more than 5 EC. On the other hand, liquids with lower electric conductivity, like hydrocarbons, de-ionized water, and boiler feed water should be used with a lot of care. Because of low conductivity, the flow meter can get turned off or show zero flow with these types of liquids.

There is an advantage with magnetic flow meter that you can use it to measure pure, corrosive, dirty, as well as abrasive liquids, because it doesn't offer any obstruction in the flow. However, if you are looking to use it with gases and hydrocarbon liquids, then it is totally worthless, as they are non-conductive in nature.

Mag flow meter can be mounted in the short meter run, as it doesn't require a great deal of upstream or downstream straight run. From the plane of electrodes, 3 to 5 times of dia. of up-stream and 0 to 3 times of dia. of down-stream straight run is enough for this instrument.

Usually, this flow meter is used, where the liquid is fed in the tube by the use of gravity. You have to make sure that the orientation of magnetic flow meter is managed in such a way that the instrument is completely filled with the liquid. In case, you failed to ensure these two important things, you must be ready to deal with inaccurate readings from the flow meter.

You have to be more attentive, while using the magnetic flow meter in the vacuum services. There are more possibilities of instrument collapse in such circumstances. If the instrument got sucked in the pipe during vacuum service it can easily cause catastrophic damaging of the flow meter. On the other hand, if the instrument is working with excessive temperature of the liquid, then there are very high chances of permanent damaging in the magnetic flow meter.

• Magnetic flow meter is a volumetric measuring instrument; that's why you must ensure its proper placement, before using it.
• Make sure about the conductivity of liquid whose flow has to be determined. The meter will not work with DE-ionized water and hydrocarbons, as it is compatible with liquids having conductivity of 5 EC or more.
• Allowance should be given for the change in composition of liquid.
• In typical cases the maximum flow measurable with this instrument is 2 or 3 m/sec. it’s essential to consider the points, which differential pressure restraints, as well as, states of flow-tube that can make the application of common guideline unacceptable.

As energy bills are soaring around the world customers are looking for solutions to cut down on the power bills and use energy more efficiently. Energy efficient lighting solutions, heating solutions and appliances do help but you still have to use energy judiciously to cut down on your energy consumption. Smart Meters have offered some respite to the consumers as it allows them detailed information about their energy usage and helps conserve energy. These meters have many advantages over the traditional electric meters that we have used for decades. In fact traditional meters did nothing more than keeping track of how much energy you have consumed. Let us now take a look at some of the advantages that these Smart Meters have over the traditional electric meters.

• Smart Tracking

Firstly they track our energy consumption smartly and give us insights into our energy consumption. These insights help us know our usual habits (which many of us aren't aware of) with energy consumption and help us in using this precious resource much more efficiently.

• Prevents Overload

Overload was one of the major problems that all of us would have faced when using multiple electrical devices in our homes. Smart Meters come fitted with a kill switch that limits our energy consumption to the maximum amount of power that we are contracted for. This prevents overloading and damaging our expensive electrical appliances.

• Fairer Bills

With these meters installed you will pay only for what you use. These meters directly communicate with our energy suppliers and give us real-time data on our energy consumption.

• Preserve Privacy

There is no need for the service provider to visit your house and take the reading as your bills are calculated automatically based on your energy consumption. This helps is preserving privacy which is important for many consumers.

• Efficient Usage Option

Another great advantage of using smart meters is that it provides you with greater control over your energy consumption. There are some suppliers who offer you time-based rates (peak and off-peak). This give you more options in managing your electricity consumption and bills.

• Instant Alerts

On many occasions your energy consumptions soar as you aren't aware of how much electricity you are consuming. Suppliers are coming out with instant alerts via messages and email which will offer you intelligence on your energy consumption thus helping you use energy judiciously and cut down on consumption.

• Inactive Consumption

There are some appliances which can actually consume a huge amount of electricity even when they are in inactive mode. Most of us weren't even aware of the energy consumption in such inactive mode but with Smart Meters we can be aware of such consumption and cut down on them.

These are some of the advantages that Smart Meters offer us over traditional electric meters. Engineers around the world are working on many more innovative solutions which will help customers cut down on the wastage of energy give respite to their pockets as well as to the environment.

Our energy needs and dependence on electricity and gas has increased many folds in the last few decades. We depend on appliances for most of our daily chores. Energy bills and gas bills account for a major spending every month for households. Technically it is very difficult to cut down on energy usage but we can definitely reduce the bills by adopting smarter solutions. One of the easiest ways to do so is by using Smart Meters. These meters give us more control over our energy consumption allowing us to cut down on energy consumption substantially by avoiding wastage of energy.

It has been estimated that every household spends about 54% of the energy for heating and cooling alone and most of the energy wastage occurs in running these appliances. Thus one of the ways to consume lesser energy would be to ensure that our air conditioners and water heaters are used more efficiently. Smart Meters help us in consuming energy efficiently.

Why Are Smart Meters Smart?

The traditional household meters charge us based on the total energy consumption per month. What such meters cannot tell us is how much energy we are consuming during particular phases of a day for instance during the peak hours. Smart meters on the other hand the fees on a per-hour basis. They directly communicate with your energy supplier and ensure that the bills are more accurate helping you pay only for what you use. Let us now take a look at some of the advantages that these meters offer and how we can cut down on the energy consumption in our daily lives.

• These meters give us near real-time information on energy use that is expressed in pounds and pence. When you are armed with this information you can easily cut down on the energy consumption during peak hours when some suppliers charge you a higher tariff.
• Such meters have the ability to manage energy use. All the energy that comes from the supplier to our house in used in a much more efficient way by preventing any leakage. This means that you can save money and reduce emissions for a better future.
• As we have discussed earlier Smarter Meters are bringing an end to estimated billing. The supplier doesn't need to come to your home to get the reading as the meter constantly communicates the same to your supplier. Thus you pay only for what you use.

However switching to Smart Meters alone won't help you reduce energy consumption as you need to adopt more energy efficient appliances and lighting solutions in your home. For example traditional halogen bulbs waste about 80% of the energy as heat and convert only 20% energy into light. Switching to CFLs and LED lights you can cut down on the consumption by about 75%. Maintaining your air conditioners at 77°F/25°C and turning them off before leaving home can also reduce the consumption of energy. You can also alternate between a fan and an AC to reduce energy consumption.

Various types of industries require measuring the flow of a liquid or gas. Several technological upgrades over the years have helped in efficient measurement of the same. For instance, a water flow meter is useful in measuring the flow of water in residential premises as well as in industries. This helps in accurate distribution of water in homes, industries and commercial establishments. In addition, it is quite useful in determining water leaks as well.

There are two major types of flow meters, which are specified below:

1. Positive Displacement Meter
2. Velocity Water Flow Meter

Positive Displacement Meter: The Positive Displacement Meter is perfect for low usage, such as in homes and apartments. This type of meter compares the flow of water by comparing the current amount of water held in the chamber with the previous quantity. It provides a fair idea of the total quantity of water consumed.

Velocity Flow Meter: The Velocity Flow Meter makes use of the velocity of water flow to determine the quantity of water consumed. Intricate mechanisms are made use of in measuring the velocity of water. Various types of velocity meters are used in different industries. The most common ones include multi-jet meters, venture meters, orifice meters, ultrasonic meters, magnetic meters and turbine meters.

The Velocity Flow Meters are perfect for measuring huge quantities of water accurately. Hence these are preferred in heavy industries where there is a substantial consumption of water daily. Certain industries make use of flaw detectors as well for accurate measurement of the water flow. One can choose among multiple varieties of water flow meters. These meters are capable of measuring even a small trickle of water accurately. In this way, accurate measurements can be obtained for billing purposes.

A Digital Water Meter is worth mentioning here. It measures the quantity of water consumed in cubic meters or cubic feet. Owing to its high accuracy, it is preferred for installation in homes and offices. Installing it is pretty easy and it has loads of interesting features. It makes use of high end technology to measure water flow accurately and display the reading in real time with an attractive digital meter that can be configured in myriad ways.

Water leakage at any point in the supply line can prove to be dangerous. If the problem is not addressed immediately, it can lead to severe accidents. High end water flow meters available in markets these days can indicate water leakage and pin point to the exact location. This essentially helps in fixing the issue well before it can cause severe structural damage and cause loss of life and property. When shopping for water meters, make it a point to discuss this aspect with your vendor.

Make sure that you spend sufficient time and effort in locating a water flow meter supplier that satisfies your requirements completely. If needed, check out the feedback given to it by its previous clients on various Internet portals. You would want to be completely sure about its quality to ensure accurate measurement of water flow.

When does the need of measuring the velocity of a liquid arise? Well, there are several such scenarios in which this may be needed. For instance, a big manufacturing industry may need continuous flow of water for cooling purpose. In addition, a chemical manufacturing company will need to measure the flow of a chemical in the liquid form to ensure that just the final product has just the right mix of ingredients. Ultrasonic flow meters happen to be extremely useful in such scenarios.

Another industry that needs water flow measurement is the waste water processing industry, where it is necessary to determine the flow of water accurately. Incorrect measurement of the water flow can lead to huge losses that can jeopardize its operating margins. An ultrasonic flow meter is perfect for usage in a wide variety of industries owing to the several benefits that it provides, including absence of moving parts and high accuracy.

Measuring the flow of liquids having high turbidity is extremely difficult owing to the fact that the moving parts cannot cut through them. Besides that, chemical compatibility is another important issue to address when measuring the flow of highly reactive liquids such as acids. These liquids can react with the material of the flow meter and eat it up in due course of time. On the other hand, there is absolutely no moving part in ultrasonic flow meters and hence there is no risk of destruction of the flow meter hardware.

Way of operation

Ultrasonic flow meters have an interesting way of operation. These meters make use of ultrasonic waves that are broadcast towards the moving liquid. When these waves strike anything, these return back. The speed with which these waves return to the transmitter/ receiver happens to indicate the flow of the liquid in question.

There are three main types of ultrasonic flow meters available in the market:

1. Transmission Flow Meters
2. Doppler Flow Meters
3. Open Channel Flow Meters

Transmission Flow Meters: Transmission flow meters can be further classified as clamp-on (non intrusive) and in-line (intrusive) transmission flow meters. These meters work by measuring the rate at which ultrasonic beam is returned after hitting a particle.

Doppler Flow Meters: Doppler Flow Meters make use of Doppler Shift that emanates due to the reflection of an ultrasonic beam when it hits sonically reflective materials. These flow meters are perfect for measuring the flow of slurries, gases that have sound reflecting particles and liquids with bubbles. These meters can also be used for measuring the flow of blood. These meters, however, are not suitable for measuring the flow of clear drinking water.

Given the several advantages of these meters and the fact that there are no components that can get corroded after long time usage, these meters are perfect for usage in a variety of industries. These meters have an exceptionally long life and hence help in significant cost savings as well. If you are looking forward to installation of splendid quality meters for measuring flow of any liquid, consider the ultrasonic flow meters!

Nowadays, flow meters have become a common sight at houses as well as industries. A flow meter is basically used for measuring the flow rate of gas or liquids. The different flow rates which can be read with the help of these devices are - linear, non linear, volumetric and mass flow rates.

Flow meters are available in many varieties to meet different purposes. Of them, gas flow meters are very common and crucial devices. Gas flow meter measures and regulates the quantity of gas that needs to be used for heating, cutting, welding and several other such purposes, industrially as well as residentially.

Why Flow Meters are Widely Used?

Everyone is aware of the fact that fuel prices are going up day by day because resources are drying up. It is our responsibility and liability to save these resources for the generations to come. This makes it essential that we have a controlled usage of fuel; and for this, proper measurement device is required to manage it. Flow meters exactly serve this purpose in a customized way. For instance, the fuel flow meter acts as an indicator to show the amount of fuel left in the storage and expected duration of usage etc. These meters are also helpful in identifying any potential hazards like a possible leakage of gas or low / high flow rates.

The users of flow meters certify to the fact that these devices have helped them save gas and in turn cut down their utility bills up to a significant extent. Going by the rate of increase in fuel usage and the scarcity of the availability, soon we can expect regulatory enactment in place to mandate the use of flow meters at all places where fuel energy is utilized.

Things to Know about Usage of Flow Meters

There are many types of flow meters available in the market. However, you have to make sure that you purchase and use only high-quality devices. Always check for the quality certification as well as the credibility of the manufacturer while purchasing flow meters. Do keep in mind that if the meters are tampered by any sources, it will not only just lead to increasing your utility bill, but can also cause severe safety hazards for your house or company.

The flow meters are expected to meet certain standardized specifications mentioned by the regulating authorities in order to be sold in the market. However, there are some improper channels which release several low-quality imitations in market from time to time. To make your purchase safe, remember that the original devices are equipped with a push fit box that is sealed to offer complete protection; and the box cannot be opened or manipulated unless you break it.

The flow meters are delicate instruments and may need some changes or corrections in a couple of years or three years' time. Hence, if you suspect any malfunctioning, submit it for proper servicing at an authorized service center. Do not try to repair it yourself or ignore the need for servicing, which may lead to dangerous after effects.

Measuring the flow of liquid or gases is essentially critical for the functioning of certain industries. It is immensely important for them to measure the flow accurately, otherwise that can result in significant losses for them. Even a slight error in this regard can prove to be immensely costly. Ultra sonic meters that provide highly accurate measurement of liquid flow are immensely useful in this regard. Here are some advantages of these meters over other traditional meters.

The ultra sonic meters send ultrasonic signals through the fluid, which get reflected when any discontinuity like a bubble is encountered. The time lapse after which the signal is received back helps in determining the speed of the liquid. Some of the important advantages of the ultra sonic meters include the following:

1. Useful in a variety of industries
2. Ability to be operated remotely
3. Measure flow of different gases and liquids
4. Eco friendly and Low Maintenance Costs

Useful in a variety of industries: The ultra sonic meters are useful in a variety of industrial applications. These can be used by chemical industries, waste water management companies, and other heavy industries that need to monitor the flow of all sorts of fluids round the clock. The traditional types of meters are not suited for a number of such industries owing to their inherent limitations.

Ability to be operated remotely: Operators can operate these meters from a remote location pretty easily. These are highly advanced meters and can be controlled using a control panel that can be situated at a sizeable distance from the system being monitored. Hence, one needs not to work in a hazardous situation where there is a significant risk of getting injured owing to pipe burst or any other such accident.

Measure flow of different gases and liquids: The ability to measure the flow of various gases and liquids is essentially the biggest advantage of the ultra sonic meters. These are perfect for measuring flow of even those fluids that are pretty difficult to control. For instance, due to its high pressure and temperature, the flow of steam becomes incredibly difficult to measure, while doing that is critical for operation of power plants and certain heavy industries. The task can be completed easily using these meters.

In addition, it is not feasible to use the traditional meters for measuring the flow of drinking water and clear liquids as that can lead to quality issues. On the other hand, this task can be completed with ease using ultra sonic meters. One can go on counting the types of industries in which these meters are replacing the traditional meters for this very reason.

Eco Friendly and Low Maintenance Costs

The ultra sonic meters are quite eco friendly for the fact that these do not result in environmental pollution or sound pollution in any way. Since these meters make use of ultra sonic waves for tracking the flow, there is little or no maintenance required for them. Once installed, these can go on and on for several years without failing.

Choosing a flowmeter can be a challenging task because it comes in many varieties. Adding to this, there are several factors also which have to be closely observed while selecting the one. Hence, to help you buy the best flow system for your application quickly, some tips are being shared below.

Tips to Choose the Best Flowmeter

If you just want to note the flow of a liquid or gas in a pipeline, then buying a simple flow indicator makes sense. A flowmeter indicator for this purpose can be obtained at cost-effective rates from a reputed vendor. You can install these flow indicators easily as these don't need any external power. In fact, you can very well do without a flowmeter if the flow which needs to be measured is limited to the rate of 10%. But for convenience, you can always go with a simplified version of this system.

Cost should not be the driving factor behind your purchase of flowmeter. A flowmeter bought at cheap prices can give you only short-term advantages. If you buy a flowmeter at the expense of technical support from the supplier, then it's not worth considering. Because a cost-effective solution is one which comes with technical back-up, test facilities, and product guarantee, etc.

In order to find the perfect flowmeter for your application, you have to understand the behavior of liquid or gas passing through the pipeline. This can be defined in terms of viscosity. You have to check the resistance of liquid or gas to flow as this can affect their flow speed or velocity in the pipeline.

To be precise, in order to choose the most suitable option, you have to analyze the Reynolds number of your application, which can be done by noting down its minimum and maximum viscosity and flow rate. Once the number is calculated, you can compare it with the Reynolds range of a flowmeter to determine your selection.

Turndown ratio indicates flowmeter's ability to measure the maximum and minimum flow rates of a liquid or gas within an accurate range. Since it is difficult to ascertain the exact range of flows to be gauged, experts recommend users to opt for a flowmeter that provides wide turndown ratio for all the different types of flow variations. Choose on the basis of application:

You have to pick a flowmeter that goes well with your application. For instance, if you want to measure widest flow range, then electromagnetic meters are good. For maximum short-term repeatability, turbine meters are suitable. For viscous substances, you can opt for the relatively expensive Coriolis mass flowmeters.

In addition to all these factors, you also have to see where and how your flowmeter can be positioned for best performance. The accuracy and repeatability of your flowmeter may get affected if the area near pipeline is not clear. To ensure the flowmeter is well installed, do look for manufacturer's assistance. Another thing is that your flowmetering system should consist of compatible components such as a meter, a flow computer or such other output device. For this, you have to make sure that you buy the whole system from one supplier in order to stick to the same standards.

When it comes to measuring the flow of water, specifically the wastewater, a portable ultrasonic flow meter is the most considered gadget for the job. The gadget uses ultrasonic waves in water to calculate water circulation. Portable ultrasonic flow meters have given the upper hand compared to the mainstream physical meters simply because they are easy to maintain and because of their simple mechanical layout, they are durable. Ultrasonic meters are also ideal for measuring highly corrosive fluids where material compatibility may be an issue. Ultrasonic flow meters are installed from outside fluid pipes and use the ultrasonic transit time technique to determine the rate of flow.

If the need arises for measuring amounts of muddy fluids on a regular basis, then these volumetric circulation meters come in handy. It is of the essence to note that these gadgets only function in waters with particulates. The recommended size of the particulates should be at least 100 microns with no bubbles in the water. The flow of murky water with particles should be at least 100 particles per minute. The volumetric circulation meters will not perform accurately if the wastewater has heavy coagulated. Dense particles will definitely prevent the ultrasound dunes from moving through the fluid.

In order to achieve maximum efficiency from the ultrasonic movement meter, one needs to decide on an excellent performing machine. With various industrial firms manufacturing the gadgets, there are still many of them are bringing less worthy devices to the market. Therefore, the following factors must be considered when selecting portable ultrasonic flow meters:

A handheld monitor is considered for measuring dimensions from time to time.

• A steady process monitor is a fixed type and is needed when you have to constantly check for water flow for a widespread period.
• The maximum and minimum rates of flow also need to be considered. The same goes for process force and process heat that the meter will have to measure.
• The size of the fluid tube is also an important element to consider
• You also have a choice to select between analogue and digital results.

Selecting the appropriate ultrasonic flow meter is a factor to consider as the same goes for its usage. It is extremely important to purchase ultrasonic flow meter from a trusted supplier to ensure that you benefit from aftermarket services such as spares and repairs. Ultrasonic flow meters are intended to be used for long term basis hence the aftermarket support is very vital. The organization that you intend to buy the meters from should also offer you the range of meters to select from so that you choose the kind that suits your needs and requirements. Specifications of the ultrasonic meters may differ with intended use. The chosen supplier should educate and advise clients on capacities, efficiency and usage of the variety of meters. This will automatically lead to informed consent from the client.

The rapid growth of science and technology has led to the consequent inventions of different types of measuring instruments, which include water flow meter, air flow meter and gas flow meter. The flow meters are tools, which are used for measuring the flow of liquid, gas or air. Water flow meter is used to measure the amount of water consumed and it is used for domestic and industrial purposes. There are visually many benefits of using these flow meters. In addition to obtaining an accurate measurement of the amount of water used in homes, industries and public places, these flow meters are also beneficial in identifying water leaks. Thus, it helps to conserve water and prevents water shortages with the various types of flow meters.

There are two types of gas flow meter for measuring the amount of water used. The positive displacement meter and the velocity water flow meter. The positive displacement meters are found in most of the homes and apartments as it measures low flow accurately. In these meters, the mechanism involves measuring of the flow in comparison to the previous volume of water, which is held in the chamber.

The total number of times this particular chamber is filled and emptied account for the amount of water used. In the velocity water flow meter, the velocity of the flow calculates the volume of water used. These meters use various mechanisms to calculate the volume of water by measuring the velocity. Some of the common velocity meters include the magnetic meters, turbine meters, orifice meters, ultrasonic meters, multi jet meters and the venture meters. The velocity meters are appropriate for measuring huge volumes of water and are therefore used in huge industries, which utilise large volumes of water.

Water flow meter is available in huge varieties though most of them are based on the two mechanisms mentioned above. Some of the flow meters can even measure the smallest trickle of water and thereby provide accurate measurements for billing purposes. Among the different varieties, include the digital flow meter, which measures the volume of water used in cubic meters or feet. The digital flow meters are installed in most of the homes, apartments and offices, as it is perceived to be more accurate. These flow meters are quite easy to install and have a number of attractive features.

The water flow meter is also beneficial in increasing the power of water supply to the source with less power consumption. It is also manufactured with additional features such as ability to withstand different types of weather, rust and scratch. There are a number of Indian exporters who supply a huge variety of flow meters such as electronic flow meter, temperature flow meter, pressure flow meter, industrial flow meter and digital flow meter. The use of a water flow meter is greatly beneficial as it prevents unnecessary wastage of water which is later utilised for other useful purposes. It also helps to provide adequate water during summers and prevents extravagant usage of water.

Magnetic flow meters are rapidly taking the place of traditional mechanical flow meter designs. While they both measure the flow of a liquid in a pipe, they do so in different ways. You will find that the magnetic flow meter has many advantages over the mechanical flow meter. Though it is more costly, the value it gives its owner is better and reliable than that of the mechanical flow meter. But this is not to say that it does not have its own disadvantages. The most common mechanical flow meters are inserted into a pipe and use a turbine, wheel or paddle to measure the velocity of the fluid or gas flowing in the pipe and then calculate volumetric flow by knowing the cross section area of the pipe in which they are installed. The most common type of the above listed mechanical flow meters utilizes a turbine that rotates as the flow of water applies a force to the blades. The rotation of the turbine is proportional to the velocity of the fluid moving past it. Once the velocity is known, the flow can be calculated.

Other mechanical meters use the same basic mechanical principles to measure flow. They operate most effectively when used in a full pipe and in an area with stable flow and little-to-no turbulence. Mechanical flow meters will operate in all types of liquids, but are prone to clogging and deteriorating performance due to solids accumulating on the turbine blades. They also obstruct a portion of the flow and require regular maintenance of the gears and moving parts. This will in long term incur a lot of money spent on its maintenance and constant changing of worn out parts.

Magnetic flow meters calculate the velocity of a moving substance using Faraday's Law. The meter body consists of a coil system, which is external to the process, but encapsulated in the meter body wrapping around the outside of the internal pipe wall, and operate by creating a magnetic field across the section of pipe. As the fluid or gas flows through the magnetic field, conductive particles in the fluid or gas create changes in voltage across the magnetic field.

This variation can be measured and used to calculate the velocity of the material flowing through the pipe. Like a mechanical flow meters, magnetic flow meters operate effectively only if the pipe is full and in areas where the flow pattern is stable. Magnetic flow meters are effective when used with any concentration of wastewater such as slurry from factories and with other water-based liquids. However, magnetic flow meters are not designed for use in distilled water, oil and other hydrocarbons, and most non-water based substances.

Magnetic flow meters are superior to mechanical flow meters because they don't impede flow, don't become clogged with solids and have no moving parts to maintain or replace. They also support a variety of liners that allow them to be used for a range of specific applications like sanitary liners for hygienic applications and inert liners for corrosive liquids.

An ultrasonic flow meter is a type of a flow meter that measures the velocity of a fluid with ultrasound enabling it to calculate the volume flow. Using ultrasonic transducers, which convert a signal in one form of energy to another form of energy, the flow meter can measure the average velocity along the path of an emitted beam of an ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow or by measuring the frequency shift from the theory of the Doppler effect, which works the same way as a moving car with a siren.

Ultrasonic flow meters are affected by the acoustic properties of the fluid, can be impacted by temperature, density, viscosity, and suspended particles depending on the exact flow meter. They vary greatly in purchase price but are often inexpensive to use and maintain because they do not use moving parts, unlike the mechanical flow meters.

The ultrasonic flow meter is a best option to use since it is easy to install on existing pipelines (there exists clamp-on versions) hence no need to buy new pipelines so as to measure flow. In addition, because it is non-invasive and there are no moving parts make it very long lasting considering that there will be no wearing off. Hence, the owner will not have to think about added costs of maintenance and frequent replacement of worn out parts.

In medical applications, doctors can avoid bleeding of patients while trying to measure their blood flow. They simply need to apply coupling gel on the skin then place a sensor pad, which will produce blood pulsation in the arteries and veins with great detail for diagnosis required by the doctor. The ultrasonic can also be used to measure the flow of slurries accurately than any other meter. Slurry by its very nature has a very high concentration of particles. The sound velocity of the particles also differs sufficiently from that of the carrier medium. The flow meter is often used to provide a signal when the velocity drops below the critical level.

The penetration depth of the ultrasonic beam, which depends on the concentration of the slurry, and the flow profile, tends to cause considerable errors of measurement. They can also be used to measure gases, which do not apply to many other flow meters. Apart from tube wall and sonic windows, no parts are in contact with the flowing gas therefore, there will not be any hazards. However, sound cannot be transmitted in a vacuum. So transmission of sound between the sensors requires that the gas have a defined minimum density.

The ultrasonic flow meters are also redundant. The signal converter activates an alarm in the event of a sensor-measuring measuring path) failure. The flow meter, however, remains operating within its specified accuracy because the remaining beams are not affected and continue to work accurately. This makes the ultrasonic flow meter much more reliable than other flow meters.

Whichever the digital flow meter one chooses to purchase, one must have valid reasons and numerable considerations to how well it will serve you.

1. Reason why you want the flow meter: Many people just want to know the rate at which a fluid or gas is getting used up but go on to purchase a digital flow meter which, in their case is not necessary. A simple flow indicator and not a digital flow meter will suffice for this reason. Simple and easy to install and requiring no external power, a flow indicator can be used to provide a local indication of flow.
2. Cost over efficiency: Same case applies here. You will find a number of people choosing a digital flow meter by considering the cost alone. The cheapest does not mean it is the best. Although it might seem the best way to save money in the short term at the moment of purchase, opting for the lowest cost solution may potentially result in many problems later down the line that one could have avoided. These problems might even be more costly than the original price of the flow meter.
3. Profile the flow you want to measure: One should know the flow of the fluid or gas they want to measure first before purchasing a digital flow meter. This helps narrow down the choices of digital flow meters that suit one’s interest.
4. Widest turn-down ratio: Turn-down ratio is a flow measurement term that indicates the range of a specific flow meter, or meter type, is able to measure with acceptable accuracy. It is virtually impossible to know in advance the exact range of flows to be measured, therefore selecting one with the widest turn-down ratio helps.
5. Best accuracy: it's obvious. The reason one requires a digital flow meter is accurate. So directly, choose the one with the best accuracy.
6. Calibration: Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one flow meter and another measurement made in as similar a way as possible with a second flow meter. One should choose a flow meter that can be recalibrated to suit your application rather than the manufacturer’s application.
7. Alarms and alerts: A digital flow meter that is connected to a telemetry network can send you an alarm if anything goes wrong, giving you confidence that the flow meter is installed, working, and measuring correctly. Some flow meters can also tell you the amount of sediment so you know when it is time to give them a clean to maintain high flows with low head loss.
 
8. Tolerance to silt and sediment: Deposited silt changes the cross-sectional area of the flow meter and this generally causes the flow meter to over read. Best to consult your supplier if silt will be an issue beforehand.
9. Head loss: this is loss of energy as a fluid moves through a flow meter. The owner should first consider if they can afford a head loss before purchase.
10. Future proofing: Look for flow meters that have an upgrade path, that are modular and allow components to be added or replaced when technologies change or your budget allows. Avoid something that limits your options.

An outstanding wireless telemetry device should be simple to set up. Ask the provider about how doing this and evaluate whether you can do it yourself, or whether you need to hire someone to do the set up and installation for you. An outstanding manufacturer will consider how an item is going to be used and set up, as an aspect of the design, and also provide outstanding guidelines that make set-up easy and uncomplicated.

There will be an antenna at each end and these may vary from a small inbuilt integrated antenna, for a short range performance, up to high-gain Yagis with many components, just like a TV aerial. Yagis concentrates the transmitting and are used for transmitting over more time tracks. They need to be set up on the outside of a building, or perhaps on a rod. If you do not have enough transmission, go higher. If you happen to own a satellite TV, a huge parabolic plate may suit you better. However, at the remote end, take a close look at how the manufacturer suggests you do the installation (or other device), to the transferring component, supposing they are individual models.

How does the battery power connect? Is it rechargeable? If so, how does it get charged? For example, does it come with a solar charger?

At the base place, there may be special applied that you fill onto a PC. The recipient is likely to link straight to a USB outlet on the PC via a standard USB wire. It does not come simpler than this, but make sure the USB edition (USB 1, 2 or 3) of the WI-Fi telemetry system receive component is suitable to that of the PC, or the connection may not work effectively. Check that the specifications of the PC satisfy the minimum specifications of the application, so that it will run properly.

The WI-Fi telemetry system remote must be strong enough to endure in the surroundings you want it to function in. If it’s cool, hot, wet, oily or dirty, then consider what level of Ingress Security (IP) the Wireless Telemetry System will need. If you will be using the sensor/transmitter outside, in the dirt and rainfall, then make sure the IP ranking should be at least IP66. Otherwise you will need to offer a fence to secure it.

Also, consider any get in touch with with oil or substances, and… If there is any opportunity that the digital program will have to endure in a condensed atmosphere, take a close look at the IP ranking. Consider an IP68 ranking with the producer’s suggestions for the particular item. Contact the maker straight for guidance if you are uncertain about this. They should know more about their own item than anyone else.

Consider the heat temperature range of the surroundings that you will be using the WI-Fi telemetry remote device in. Make sure to look at the extreme conditions. If it has to perform in sub-zero heat range ranges, then make sure that its requirements assures it will continue to perform down there. If it has to perform at raised heat range, make sure you choose a product that is assured to perform at a higher heat range than the highest possible.

Wireless Telemetry allows you evaluate factors at a distant range, without having to be there, even if they're shifting. It can decrease functional expenses, allows you avoid risky locations and allow you to get details almost as soon as it happens... from distant or in -accessible locations, without having to go there to gather the details yourself.

There's nothing as interesting as like being able to look in on events and activities, as they are occurring, to provide you the assurance that factors are OK, and to know that you could be notified instantly if something changes and isn't OK any longer.

And wireless telemetry can preserve resources... to suit your personal needs or for the company you work for and the globe.

Think of enough efforts and journey expenses that you could preserve by changing guide statistic with a computerized electronic process that may mean that you wouldn't have to journey at all. This wireless technology can improve the performance of some procedures by an incredible rate.

Don’t spend your money permanently going to evaluate or obtain information. Getting information from distant or not reachable places comes at a cost, but wireless telemetry can decrease this e.g., If your selling machines had WI-fi telemetry they could instantly tell you when to restock.

You don’t have to be held at. You can see what exactly is occurring, immediately, as it happens.

For example; Sports activities, such as the The united states' Cup luxury boat regatta, telemeter position, speed, wind circumstances and other details to help produce the design that show competition improvement on TV, in near real-time.

Telemetering users in a health care center, or at a house, can give early caution of serious changes in their health care problem, enabling fast reaction from the health care team. Telemetry Medical is a growing area of improved individual care.

This type of tracking allows users to go back house from the health care center early… a win-win situation for everyone and especially helpful if the effects of drugs have to be supervised careful.

Because most telemetry uses stereo, it makes no difference if what your calculation is shifting, as long as it remains within stereo range.

For example; You can telemeter the crucial factors of rushing vehicles or vessels during a competition.

• Or the twisting of a quickly spinning generator base.
• Or track creatures.
• Or get information about environmental circumstances from a climate increase.

Being in digital form, information can quickly, and often instantly, be integrated into other techniques.

For example; Household power meters may be telemetered and the calculated amount of electric energy used at each location instantly fed into a data source, ready for payments.

Evaluate factors that may be destroyed

Wireless telemetry is a fantastic way to get details during a analyze, when the factor you are examining might end up being damaged.

For example, dangerous examining is often used to confirm the boundaries of developing components or automobiles and details sent back, just before the factor of devastation, provides useful details for changing the style.

The Water Flow Meters as all of us know that accurately measure the flowing rate of slurries or conducting liquids through the closed pipes. These resist voltage fluctuations and enable to give accurate readings. These easy to use meters are available in the market in various configurations and are designed as per the requirement of the client. Thus it is intended to gauge the amount of water being used by the people both for both domestic and commercial uses.

A telemetry system helps you in delivering information from different locations, even from a very distant place, moving and dangerous for where it is difficult for you to collect the data. It also delivers you the useful results in a very inexpensive manner just right to the comfort of your home.

If for any reason you need to measure something in a difficult place then don’t hesitate to take the help of a telemetry system. Moreover if you are not comfortable with the wires associated with it then you can go for the wireless ones. However the system is trustworthy if you follow a few simple guidelines. The best way of doing things is to avoid the risk from the very beginning.

This new technology of wireless telemetry system product is easy to install. You can install it by your own or else can take the help of an expert person in doing the same.

There are various types of wireless telemetry system exist which we are going to discuss below with the available options, benefits and issues associated with the products.

Some product shares only one channel, whereas the others have several.

Here generally you have the choice of digital, analogue, serial digital or a mix of these. Always make sure that the input to the network should be well-suited to the output derived from the sensor or any other device attached to the process.

Certain wireless telemetry systems use a single integrated module for sensing and transmitting the functions. Just like an instance of a wireless accelerometer if you need one sensor channel then you can have the advantages of doing everything in the one module. And if you need several channels, then you’ll need numerous items such as the transmit unit plus the sensors.

Other types of wireless telemetry systems will able to transmit a continuous flow of a stream of data from the measurement site. This kind of system is effective in some telemetering operations like monitoring race cars and other which require fast retrieval of information, while need to be regulated in real time. However as it deals in a continuous process it need more power than ever before. Check out at the processing ends...

If your measurements need the data from one single location then you can go for a single node wireless telemetry system. If on the contrary you need to receive measurement information from several different locations, just select multi-node wireless telemetry system having the capacity of handling that number of nodes.

Good wireless telemetry systems should also deliver information about the condition of the power supply at the measurement end. The important issue here is that you need to know the status of the power supply voltage as you can intervene before any miss happening takes place.
