Series GFC Gas Mass Flow Controller (Model GFC-2110)
Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable.
* (Range 0-10 LPM) Specified flow range is for an equivalent flow of nitrogen at 70°F (21°C) @ 760 mm Hg, 1/4" compression fitting.
The SERIES GFC Gas Mass Flow Controllers combine a straight tube sensor with a restrictor flow element. It is available for flow ranges up to 1000 L/min and offered in aluminum or 316 SS in 1/4", 3/8", 1/2" and 3/4" sizes.

- Provides high accuracy and repeatability
- Flow rates are virtually unaffected by temperature and pressure variations
- Utilizes an electromagnetic valve and PID electronics to maintain continuous control by comparing measured sensor signal set to flow rates
- Set points can be adjusted with local potentiometers or remotely via 0 to 5 VDC or 4 to 20 mA analog signal
- Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout
- Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
- NIST traceable certificate included
