GFM-1101 is a series GFM gas mass flow meter combines a straight tube sensor with a restrictor flow element to provide high accuracy and repeatability. Flow rates are virtually unaffected by temperature and pressure variations. Actual gas flow is displayed in engineering units on a 3-digit, 90° tiltable LCD readout. Units can be used with series GFT flow totalizer for applications requiring totalization. Series GFM includes a NIST traceable certificate.
