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 series now 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

The instruments offer IP67 / NEMA 6 protection against solid particles and water

ATEX Certification

red-y industrial devices come along with ATEX certification (Category 3 / Zone 2 & 22)

Multiple Connections

The red-y industrial series is available with different connection types: Cable gland with compression fitting or optional M12 plug on top

Setup Tool get red-y

Efficient device setup with the free get red-y software:

  • Service tool for remote maintenance
