RS 485 interface, Modbus RTU, 4...20 mA analogue output for m³/h, Pulse output for m³.
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
