Dwyer GFM Series Gas Mass Flow Meter & Controllers


 

Dwyer GFM Series Gas Mass Flow Meter & Controllers combine 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 3-1/2 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. Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable.

Note: These units require a cable, see GFM-CBL4 or GFM-CBL5, depending on your needs.
