Flow meters | What is How it Works

May 10, 2019· A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. When choosing flowmeters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site.

Flowmeter Selection Guide: Types For Application ColeParmer

Mar 31, 2021· The capillary includes two external heatersensor coils, one downstream from the other. Gas flow carries heat from the upstream coil to the downstream coil. The resultant temperaturedependent resistance differential at each coil is then measured. The gradient at the coils is linearly proportional to the instantaneous flow rate.

PRESSURE OR AIRFLOW SENSORS?

or absence of a gas flow path. For a mass flow sensor to operate properly, gas must be able to flow through it. Any restriction in the flow path, such as dirt or liquid, will change the pneumatic resistance and therefore the output. In contrast, a pressure sensor is ‘dead ended’. The only gas flow in its tubing system is the small amount ...
