How to Pick the Right Gas Flow Meter

Share:

There are many reasons to invest in a flow meter for your gas application. By constantly monitoring the flow of gas at your facility, you are able to detect leaks and reduce wastage. By checking the flow, you are able to enhance safety and also increase efficiency in the delivery of the flow to the required points. Gas meters are used in industrial, commercial and residential settings where this product is used.

Whatever your application, measuring the accuracy of gas flow is crucial and if you are shopping for a flow meter to help in this, you need to get more insight on the same. There are different types of flow meters including mass flow, velocity, differential pressure meters and positive displacement flow meters. With the right information, it becomes easier to buy a flow meter that is suitable for accurately measuring gas flow.

Differential pressure flow meters –This type of gas flow meter relies on Bernoulli’s principle where the measurement of gas flow is equated to a pressure drop over an obstruction on the path of the gas flow. They include the orifice plate and averaging pilot tube.

Velocity flow meters – These flow meters measure velocity of the gas flow at one point or more points and then work out the flow velocity over the area. They include turbine flow meters, ultrasonic flow meters and vortex flow meter.

Mass flow meters –These determine the mass of the gas flowing through the flow meter. They include the coriolis flowmeters and thermal mass flow meters.

Positive Displacement –These include the Reciprocating Piston Meter, Nutating Disc and Rotary Vane Meter.

It is important to get the specification on the flow meter you choose in order to determine whether it will suit your unique application. It is advisable to choose a fast response flow meter and check the accuracy of the device. A trigger alarm will also come in handy in gas measurement and control and this should be a component of the flow switch you buy.

Buying the Best Gas Flow Meters

It is important to start your flow meter shopping process by determining what you need for your application. For instance, determine the type of flow you have as this will determine the type of flow meter you will buy. Once you have determined your needs, including the unique application requirement flow rate and any other needs, it is now time to go to the market.

As a rule of thumb, you should not be guided by cost alone. Instead, you should consider the brand reputation and read reviews for the flow meter you want to buy. It is important to go for the widest turndown which is defined as the ratio of the maximum and minimum flow rates a flowmeter can measure within its specified accuracy range.

Other factors to consider include ease of installation and maintenance. Go for a low-maintenance appliance which will not require regular maintenance and repairs. You should also ensure the supplier will offer necessary support if need be. A warranty will also come in handy to assure you that the flow meter is highly functional.
