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
