Explanation of the device code

GFC17A-ABCD-EF-GAS-FLOW

  • A = type of seal
  • B = fitting size (connection)
  • C = display (L = including display, N = no display)
  • D = power supply (2 = 12VDC, 4 = 24VDC for GFC 57, 67 and 77, 6 = 12 to 26 VDC for GFC 17, 47 and 47)
  • E = output (A = 0 to 5 VDC, B = 4 to 20 mA – local, C = 0 to 5 VDC / 0 to 5 VDC, D = 0 to 5 VDC / 4 to 20 mA, E = 4 to 20 mA / 4 up to 20mA, F = 4 to 20mA / 0 to 5 VDC)
  • F = digital output (always = 0)
