Digital Flow Meter VA-500/520

Monitor and control compressed air usages and wastage.

What is the digital flow meter.?
Digital flow meter is easy way to monitor compressed air consumption and waste. The digital display show the exact amount of compressed air being used, making it easy to identify costly leaks or inefficient air products. Many companies install the Digital flow meter on each major leg of their air distribution system to constantly monitor and bench compressed air usage.

Flow meter work according to the calorimetric measuring principle. This means, while measuring the thermal mass flow or standard volume flow, no additional temperature and pressure compensation is necessary. The standard volume is a common volumetric unit used to compare gas quantities at different pressures and temperatures. In order to meet various standards, the reference conditions can be set directly on the display of each flow meter. Thus, our reliable flow meters provide consumption and flow measurement within the individual standard our customers wish to use them.

Flow sensor for compressed air and gas:
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 11000.

Special features of flow sensor:

  • RS 485 interface, Modbus-RTU as a standard
  • Option integrated display for m³h and m³
  • Usable from 12“ to 12“ (DN 300)
  • Easy installation under pressure
  • 4…20 mA analogue output for m³h resp. m³min
  • 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
