GFC Analog Mass Flow Controller

The GFC Series Compact Thermal Mass Flow Controllers are self-contained instruments engineered to precisely indicate and control gas flow rates with exceptional stability and repeatability. Combining rugged metallic construction with instrumentation-grade accuracy, the GFC delivers reliable mass flow measurement and closed-loop control in a compact, economical package. Advanced thermal sensing technology, an integrated electromagnetic control valve, and multiple output and display options make the GFC an ideal solution for both laboratory and industrial gas flow applications, even where temperature and pressure variations are present. Available in aluminum/brass construction for non-corrosive gases or 316 stainless steel for corrosive applications. Features a tiltable, built-in LCD readout with selectable engineering units or 0–100% display for easy local monitoring. Controllers are calibrated for nitrogen (N2); models calibrated for other gases can be special-ordered; contact us for a quote. Transducer power supply ports are fuse and polarity-protected. Power supply sold separately: 97764-97771 and 97775-97782 have universal 12VDC to 26VDC power requirements, while 97772-97774 and 97783-97785 have 12VDC power requirements.
