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


Parameters: m³/h, l/min (1000 mbar, 20 °C) in case of compressed air resp. Nm³/h, Nl/min (1013 mbar, 0 °C) in case of gases 

Units adjustable via keys at display: m³/h, m³/min, l/min, l/s, ft/min, cfm, m/s, kg/h, kg/min, g/s, lb/min, lb/h 

Adjustable via keypad: Diameter for volume flow calculation, counter resettable

Sensor: Thermal mass flow sensor

Measuring medium Air, gases

Gas types are adjustable over CS service software or CS data logger: Air, nitrogen, argon, helium, CO2, oxygen, vacuum

Accuracy: (m.v.: of meas. value) (f.s.: of full scale) ± 1.5 % of m.v. ± 0.3 % of f.s. on request ± 1.0 % of m.v. ± 0.3 % of f.s.
