Model VA 525

The newly developed VA 525 combines modern digital interfaces for connection to an energy monitoring system with a small, compact design. Due to its reasonable price and modern digital interfaces this compact in-line flow sensor is used when many machines (compressed air consumers) are to be integrated as easily as possible into an energy monitoring network.


  • Compact, small design – for use in machines, behind maintenance unit at the end user

  • Optionally with classic analogue signals(4…20 mA and pulse) or digital interfaces such as Modbus RTU, Ethernet (also PoE), M-Bus

  • All interfaces are programmable via the display

  • Current consumption in m³/h, l/min,…

  • Total consumption (meter reading) in m³, l, kg

  • Temperature measurement

  • Optional: pressure measurement

  • Easy installation in existing piping through integrated measuring block (suitable for 1/4 ̋, 1/2“, 3/4 ̋, 1“, 1 ¼ ̋, 1 ½“ or 2″ lines)

  • Display values can be rotated 180° in the display, e. g. when installing overhead
