Dwyer GFC Series 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


  • Gas flow measurement
  • Gas flow control
  • Operating pumps and valves
  • Process equipment
  • Vacuum processes
  • Glass and metal coating
  • Film deposition
