Part Number : GFM-1102

A restrictor flow element and a straight tube sensor are combined in the Model GFM-1102 Gas Mass Flow Meter to offer excellent accuracy and repeatability. Temperature and pressure changes almost never have an impact on flow rates. Measured gas flow is shown on a 3-1/2 digit, 90° tiltable LCD readout in engineering units. When totalization is needed, units can be utilized with the Series GFT Flow Totalizer. comes with a traceable NIST certificate.
