Field of application:

  • Technical gases
  • Mixed gases
  • Compressed air in PET bottle production
  • CO2
  • LPG
  • Propane
  • Krypton

Advantages of the Vortex flow meter VU 570:

  • Precise measurement starting at 0.3 m/s
  • Suitable for unknown or changing gas compositions and mixed gases
  • Rough industrial applications can be realised due to robust aluminium housing
  • Measures operating volume flow and mass flow
  • Measurement of the standard volume flow through integrated pressure and temperature measurement
  • The innovative measuring principle guarantees precise flow measurement in different gases
  • Suitable for rapidly changing temperature and pressure changes as well as large mass flows
  • Larger measuring span than usual vortex flow sensors
  • No moving parts, therefore low maintenance effort
  • Negligible low pressure loss due to negligible low blockage of the diameter

Technical details of the Vortex flow meter VU 570:

  • 04…20 mA, pulse and a Modbus RTU (RS 485) interface as standard
  • Optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
  • Pressure range up to 40 bar
  • Protection class IP 67
  • Temperature range from -40°C to 100°C
  • Integrated display for showing the measured values
  • Available from DN15 to DN80
  • Settings adjustable via the buttons on the display
  • Main counter reading can be reset via the display
  • For velocities from 0.3 m/s to 30 m/s
  • High accuracy of 1% deviation of the measured value
