Details

Measurement of mass flow rate, output of standard volume flow rate
High accuracy for both small and 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.

04...20 mA, pulse and a Modbus RTU (RS 485) interface as standard, optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
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 velocities 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
