Details

  • Measuring the mass flow, direct output of the Standarized volume flow
  • Highly accurate for both small and large flows
  • Pressure and temperature-compensated thanks to the thermal mass flow principle
  • Easy installation and removal of the sensor, the integrated measuring section can remain in the pipe for cleaning or recalibration of the sensor and can simply be closed with a cap
  • No moving parts, therefore Low maintenance
  • Disappearingly low pressure loss due to extremely low blockage of the diameter
  • Can be used for Compressed air and non-corrosive gases such as Nitrogen, Oxygen, Argon, Helium, etc.
  • 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 Measuring
  • Pressure range up to 40 bar
  • Temperature range from -30 to 80°C
  • Protection class IP65
  • Integrated display for showing the Measured values
  • Can be used from DN 8 to DN 80
  • Settings can be adjusted using the buttons on the display
  • Main counter reading can be reset via the Display
  • For Velocities up to 224 Nm/s
  • Highly accurate with an Accuracy of ± 1.5% or ± 1% of the Measured value and ± 0.3% of the final value
