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
