Use our GFM series flow meter for measuring flow rates of bio-gas, LPG, compressed air, steam (saturated & superheated) in closed pipes. The flow meter is suited for wide range of applications where affordability, reliability and ruggedness are of prime importance.
In conventional system of measurement, the differential pressure generated by orifice plate is measured by D.P. transmitter. The output from D.P. transmitter after square rooting is accepted as proportional to flow - rate. This assumption is true only when density is constant.
Unfortunately, density of compressible fluid is never constant. The density of compressible fluid changes with line pressure & line temperature. Thus, introducing errors in flow rate measurement.
