SGW gas turbine flow meter which assimilates the advanced turbine technology of flow meters digital for gas from China and overseas with optimum design, is a new generation of gas flow meter with high precision and reliability based on the theory of pneumatics, hydromechanics ,electro-magnetic etc. Turbine gas flow meter has excellent performance under both low and high pressure , various ways of signal output and low sensitivity to the fluid turbulence,. Thus gas turbine meter is widely applied to the measurement of gas flow, such as used as natural gas flow meter, n2 flow meter (Nitrogen flowmeter ) ,biogas flow meter, LPG gas flow meter or industrial air flow sensor. SILVER AUTOMATION INSTRUMENTS is reliable gas turbine flow meter China manufacturer.
