GFM-2144 Series GFM Gas Mass Flow Meter, Stainless Steel, Range 0-500 LPM. Specified flow range is for an equivalent flow of nitrogen at 70°F (21°C) @ 760 mm Hg, 1/2" compression fitting.

Flow Range Up to 1000 L/min, Pressures Up to 500 psi, NIST Traceable

Series GFM Gas Mass Flow Meters 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.
