GFM
GFM low priced aluminum or stainless steel thermal mass flow meters
Downloads
GFM are compact mass flow meters designed to measure flow rates of gases. Using thermal mass flow metering, these meters offers accuracy and high cost efficiency.
Each of these meters is equipped with an advanced “U”-shape tube sensor in conjunction with flow passage elements constructed of aluminum and brass for non-corrosive gases or 316 stainless steel for corrosive applications.
The LCD readout built into the top of the transducer is tiltable over 90 degrees to provide optimal reading comfort. It is connected to the transducer by a standard modular plug, and is readily removable for remote reading installations. Transducers without LCD readout are offered for OEM applications.
GFM mass flow meters can be configured for flow ranges from 10 smL/min to 1000 sL/min N2. the meters can by connected to the process 1/4”, 3/8”, 1/2” compression fittings and 3/4” FNPT fittings. Optional fittings are available. They can be used as benchtop units or mounted with screws in the base.
GFM can be upgraded with a TIO to add digital communication, Up to 47 different volumetric and mass flow engineering units and Totalizer.
