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
