Overview
Details for GFM-1108
Gas mass flow meter | range 0-2 LPM. Specified flow range is for an equivalent flow of nitrogen at 70┬°F (21┬°C) @ 760 mm Hg | 1/4" compression fitting.
Series GFM Gas Mass Flow Meter
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.
Note: These units require a cable, see GFM-CBL4 or GFM-CBL5, depending on your needs.
