Details

All wetted parts are made of stainless steel, especially for applications with high demands on cleanliness and surface quality
Robust aluminium housing enables use in harsh industrial environments
Recommended for flammable gases such as Natural gas, hydrogen, Biogas, etc. due to ATEX or DVGW approval
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
Quick and easy installation via a standard ½'' Ball valve
No moving parts, therefore Low maintenance
Disappearingly low pressure loss, as the blockage of the diameter is negligible

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 50 bar, special version up to 100 bar
Media temperature range up to 180 °C (ATEX version up to 120 °C)
Protection class IP 67 (IP 64 for ATEX II 2D Ex tb IIIC T90°C Db)
Integrated display for showing the Measured values
Suitable as insertion version for 3/4" to DN 1000
Simple installation under pressure
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 - As well as ± 0.3 % of the final value
