Aalborg Instruments Low Cost Mass Controller GFC77A-VFDL2-A0

Model GFC thermal Mass Flow Controllers are designed to indicate and control set flow rates of gases. The GFC combines the characteristics and accuracy of conventional mass flow devices into a unique compact design at low costs previously unattainable. Each of these controllers incorporates an advanced straight tube sensor in conjunc- tion with flow passage elements constructed of aluminum and brass for non-corrosive gases or 316 stainless steel for corrosive applications. Zero and span adjustments are accessible from the outside of transmitters.
