Accurate and reliable thermal mass flow meters and controllers

Category: Tag:

Red-y smart series of thermal mass flow meters and controllers use reliable technology and standardized interfaces, and are particularly suitable for measurement and control in gas delivery systems and plant engineering applications.


Precise measurement

The device offers high accuracy and a wide measuring range

2 instrument types :

‹ Standard Type › and ‹ High Performance ›

Accuracy as high as ± 0.3% of full scale + ± 0.5% of reading

Range ratio 1:100

Please inquire for higher turndown requirements.


Analog & digital signals : 2 in 1

The flowmeter and controller adopt the latest CMOS technology , digital quantity (Modbus RTU) and analog signals integrated into one electrical interface


Safe and fast control

The controller adopts a firmly sealed control valve with a leakage rate of less than 1×10-6mbarl/s He , fast control response time is about 300 ms , significantly reducing the setting time.


Working status indication

The instrument has built-in LED status indicators



Built-in displayDisplays instantaneous flow , accumulated flow and measurement unit. Set a flow value ( controller only )
Various gasesOne flow meter or controller can be used to measure up to 10 gases or gas mixtures
ProfibusThe device has a Profibus interface : DP-V0 & DP-V1 Protocols
Industrial EthernetTwo industrial Ethernet protocols Profinet RT and EtherCAT optional
