Mass air flow sensor air nitrogen argon thermal mass flow meter
Description
VA500 for flow measurement of compressed air and gases,optionally with display for flow in m3/h and total flow in m3.Contrary to the previously used bridge circuit the newly devel-oped evaluation electronics records all measured values digitally. This leads to a better accuracy also in case of large measuring spans of 1:1000.
Features
RS 485 interface, Modbus-RTU as a standard
Incl. temperature measurement
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
