The new VA 500 for flow measurement of compressed air and gases

Contrary to the previously used bridge circuit the newly developed evaluation electronics 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
  • 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 via keys at the display: Gas type, reference conditions, °C and mbar, 4...20 mA scaling, pulse weight
