VA 500

Flow meter for compressed air and gases

Flow sensor for compressed air and gas – VA 500

Contrary to the previously used bridge circuit the newly developed evaluation electronics of our flow sensor records all measured values digitally. This leads to a better accuracy also in case of large measuring spans of 1:1000.

Special features of flow sensor VA 500:

  • RS 485 interface, Modbus-RTU as a standard
  • Option integrated display for m³/h and m³
  • Usable from 1/2“ to 12“ (DN 300)
  • Easy installation under pressure
  • 4…20 mA analogue output for m³/h resp. m³/min
  • Pulse output for m³
  • Inner diameter adjustable via keypad
  • Consumption counter resettable
  • Adjustable values at the display of the flow sensor: Reference conditions, °C and mbar, 4…20 mA scaling, pulse weight
