Compact Gas Flowmeter: GFMc-150

INTRODUCTION

                      The GFMc-150 flow meter is applicable for measuring flow rates of Bio-gas, LPG, Compressed air and other compressed gases in closed conduits. It is best suited for applications where affordability, reliability and ruggedness are of prime concerns.

In conventional system of measurement, the differential pressure generated by orifice plate is measured by DP transmitter. The output from DP transmitter after square rooting is accepted as proportional to flow rate. This assumption is true only when the density is constant.

Unfortunately density of compressible fluid is never constant. The density of compressible fluid changes with line pressure and line temperature. Thus, introducing errors in flow rate measurement.

PRINCIPLE OF OPERATION:  

As per BS 1042 / ISO: 5167 standard, the equation for mass flow when measured with orifice states:                       

       

Qm ∝ √ρ. √ ∆P

Where, 

                                                                                    

Qm = mass flow rate.                                                        

ρ     = instantaneous density.

∆P  = differential pressure.
