Call for pricing

Record and reduce your energy costs and increase your sustainability with the VA 520. Monitor your consumption and analyze your leakages with a permanently installed flow meter in distribution stations, in front of individual departments or for billing purposes of individual consumers.


Special Features:

  • Measurement of mass flow rate, output of standard volume flow rate
  • Highly accurate at small as well as large flows
  • Pressure and temperature compensated by the thermal mass flow principle
  • Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
  • No moving parts, therefore low maintenance
  • Vanishingly low pressure loss due to vanishingly low blockage of the diameter
  • Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.


Technical details:

  • 04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
  • Optional: Bi-directional measurement
  • Pressure range up to 40 bar
  • Temperature range from -30 to 80°C
  • Protection class IP65
  • Integrated display to show the measured values
  • Can be used from DN 8 to DN 80
  • Settings adjustable via the keys of the display
  • Main counter reading can be reset via the display
  • For speeds up to 224 Nm/s
  • Highly accurate with an accuracy of ± 1.5% or ± 1% of the measured value - as well as ± 0.3% of the final value
