The Standard Flow Board is designed to fully simulate a dual pulse, custody transfer meter.  Some of its many features include:
  • Installable on standard DIN Rail
  • 24 VDC operation
  • All connections via plug and header, not terminals
  • Eight Frequency Ranges (0-63, 0-125, 0-188, 0-250, 0-1000, 0-2000, 0-3000 and 0-4000 Hz)
  • Two current-sourcing, output pulse trains, 90 degrees phase displaced
  • 4-20 mA input for Flow Control Valve signal
  • Can be configured for Reverse-acting Flow Control Valves (4 mA = Open)
  • Manual mode of operation for manually adjustable frequency output over the selected range
  • Either pulse output can be turned off via the DIP Switch
  • LEDs show overall health of the board (1/2 second flashing) and output status.
  • Red LED flashes as a faster rate when pulse output is disabled due to a low signal (< 4.06 mA)
