Series GFC Gas Mass Flow Controller

Brand: Dwyer Instruments, LLC
Add Product to My Catalog

Dwyer Gas Mass Flow Controller, Series GFC
The Series GFC Gas Mass Flow Controllers combines a straight tube sensor with a restrictor flow element.

It is available for flow ranges up to 1,000 L/min and offered in aluminum or 316 SS in 1/4", 3/8", 1/2" and 3/4" sizes.
Features
  • 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
