Rough Environment Mass Flow Meters & Mass Flow Controllers for Gases

Rough Environment Mass Flow Meters & Mass Flow Controllers for Gases

Reliable technology and industry standard interfaces for rough environments: Our tried and tested thermal mass flow meters and controllers for gases of the red-y smart seriesnow available as IP67 / NEMA 6 version.


Accurate Measurement

The massflow devices offer high accuracy and a wide dynamic range with the 2 different instrument versions “Standard” and “Hi-Performance”:


Accuracy up to ± 0.3% of full scale + ±0.5% of reading
Turndown ratio 1 : 100 (extended turndown ratio on request)


Analog & Digital

The red-y industrial mass flow meters and controllers make use of the latest MEMS technology and have a digital (Modbus RTU) and analog interface as standard.


IP67 / NEMA 6 Protection
