Reliable technology and industry standard interfaces make the red-y smart series thermal mass flow meters (MFM) and mass flow controllers (MFC) particularly suitable for measurement and control in gas delivery systems and plant engineering applications.
Core Features
Accurate Measurement
The massflow devices offer high accuracy and a wide dynamic range with 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 mass flow meters and controllers of the red-y smart series make use of the latest MEMS technology and have a digital (Modbus RTU) and analog interface as standard.
Profibus interface is available as option (Profibus DP-V0/DP-V1).
A wide range of cable and power supply accessories is available
Operating Status Indication
The measurement and control instruments offer a built-in LED status indication
Safe & Fast Control
The red-y smart controller uses a tightly sealed control valve with a leak rate of less than 1×10-6 mbar l/s He. Response times of approx. 150 msec for very fast set point control
