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.

Greatly decrease functional costs-

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.

Get instantaneous information

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.

Get information from things that moves with high speed-

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.

Easily integrate information into other systems-

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.

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.

Different types of wireless telemetry systems:

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.

Check out at the measurement end...

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

Multiple types of channel input:

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.

Single or separate packages:

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.

Streaming or Logging:

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...

Single node or multi-node:

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.

You get numerous benefits from using electromagnetic flowmeters to achieve fluid flow measurements. But at the same time a decrease in flowmeter pressure is also generally not larger than that of an equivalent reducing, pipe length and the piping costs.

There are some problems causing from the use of the magnetic flow meter which found within the factory.

Most peoples view that the accuracy level in the magnetic flow meter is quite good. But the truth regarding this is the amount of precision involved the wise magnetic flow meter is quite well enough. However for the relatively high accuracy, it is observed in many cases that the improper use of the flow meter cause the measurement deviation of the data. This inaccuracy is the result of the information which is caused by the failure of the gear. Therefore you should take care of all the thing in a more stricter to avoid the data losing. These high technical instruments should be used in a proper manner to get optimum result.

Therefore let’s dig into the matter that what are the causes of the failure of a magnetic flowmeter. So it is very important to investigate the reasons behind this disappointment and to solve it.

The initial issue which need the requirement to focus to is the fact that suspended solid phase or the unwanted dirt object should be kept away from the flow meter while the magnetic flow meter is working inside the measurement approach. If proper care will not be taken then those dirt will significantly enhance the possibility of failure in the inner wall of the magnetic flow meter.

Furthermore, a magnetic flow meter can only be installed in a place having adequate current interference or powerful magnetic flow. The external magnetic power produced an impact towards the sensor. The lightning strike which appears around the line down the magnetic flow meter is also really dreadful, measure are to be taken to avoid those kind of things.

Another point is dealing with the measurement procedure. In the event of changing the liquid bubble, you can take is as the result of using the electrode material and also be aware of the chemical reaction which occurs among the liquid medium and the electrodes as well. This chemical reaction produced in the process will straightway influence the regular measurement of the magnetic flow meters.

There are lots of reasons which will prove that you should pay proper consideration to numerous cases and never let things go outdoors and a have the direct impact around the measurement in the magnetic flow meter.

The most crucial thing as we all know, the regular maintenance of a magnetic flow meter is very critical. A lot of diligence and care is needed to keep the flow meter in a very good functioning condition. So this is the way that you should follow to keep magnetic flow meter in the normal work condition.

The ultrasonic flowmeter is a single-path flow meter for the transit time as it is widely popular among the people due to its recognized characteristics such as flexibility, accuracy and cost effectiveness.

As per the need and requirement of the user they go for different types of flowmeter basing upon the applications they do. One should keep in keep in mind the following things while making a proper choice of a flow meter.

1. Firstly you have to see whether the pipe is full or not because all the every ultrasonic flowmeters need the pipes being attached to it should be full of liquid. So if you are not aware of the things please take the help of a factory trained technician or the manufacturer who have expert knowledge on this to make sure that everything is well. A few effective approaches are there to workarounds for working with partially-full pipes.

2. The liquid level must have particles above 200ppm and the size of the particle should be larger than 75um depending on different manufacturers. Then you can go for using the Doppler principle.

3. Make sure that whether the liquid temperature in mostly high heat applications is falling into the transducer temperature range.

4. If you are going to choose a wetted transducer press range in the pipe.

5. Keep an eye to know the desired level of measurement accuracy. In common, the multi-path gives a more accurate measurement than in case of single path transducers, Thus the flow cell is better than insertion, while insertion is better than clamp-on. But, if you have an on-site calibration facility, it is good.

6. The flow meter should be portable that can easily move from one place to another. It should possess the capability like clamp-on solution.

7. Be careful about choosing a right type of output signals; make sure whether it is an analogue one or digital or RS232.

8. Make sure about all the security measures, safety requirements as well as considerations. All the flowmeters cannot meet the specific safety requirements for all applications, so be sure while selecting the best one or else consult with the manufacturer or a factory trained technician.

9. Always look the pipe size range, pipe material, lining and Age. These are the important things to be considered.

10. Another important aspect is the flow rate range.

11. A straight pipe length works well. To avail a desired accuracy, it is usually suggested to have straight pipe must equal to 15 times your pipe diameter at the measuring site.

12. However the budget part is also quite important. So you have to make a proper choice depending upon the requirement and budget as well. So that you can get effective benefit of your money utilized.

Almost every flowmeter available in the market must have more or less standard technologies and principles. Moreover, there are a large variety of brands exist in the market, and almost all flowmeter vendors deliver some level of good application expertise and professional services. Therefore a considerate combination of quality, accuracy and cost should be the measuring criteria of your selection.
