VA 500 - Flow sensor for compressed air and gases

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
