How to make sure the measurement of flowmeter is right?
As with a majority of other instruments that present measurements of liquid flows, you are supposed to make sure that your gas flow meter is able to settle on flow rate according to inference. Thus, it requires to measure velocity of the fluid and even changes in the fluid's kinetic energy.
The viscosity and the density of the liquid can be the important factors to affect the readings presented by this type of meter. Sometimes, you would even be advised to buy a gas flowmeter that is completed with gas sensors and flow sensors.
The electromagnetic flowmeter is another kind of meter that is widely used. This kind of meter is third only to the differential pressure as well as positive displacement flowmeters is. In such a flow meters, a magnetic field gets applied to a tube.
