Red-y smart Mass flow controller with pressure measurement

Mass flow controller with pressure measurement / pressure controller with mass flow measurement

Vögtlin's digital pressure regulator has three different functions. It can be used either as a pressure regulator, as a pressure regulator with mass flow measurement or as a mass flow regulator with pressure measurement. Thanks to its features, it is excellently suited for various testing applications.

RED-Y smart:

Vögtlin gas mass flow controllers and meters use a CMOS sensor, which makes the measurement and control response time very fast (with a controller of 150ms and a meter of 50ms). In addition, the measurement is very accurate up to ± 0.3% of full range + ± 0.5% of reading and turndown 1: 100. The warm-up time of the CMOS sensor is also short (less than 1s), so the sensor reaches full accuracy very quickly. The Smart series has both analog and digital communication and RS485 and Modbus RTU as standard, so the controller is easy to control directly from a computer. The controller uses a tightly closing control valve with a leakage value of less than 1x10-6mbar l / s He. The controller is also available with a local display as well as a display with pushbuttons with which the setpoint can be changed locally. Each meter is calibrated separately with the gas used in the application. One meter can be calibrated with up to ten different gases. Get red-y software is available free of charge for mass flow controllers and meters.


  • Accurate measurement and adjustment in the standard model ± 1% of the total range (turn down 1:50) or High performance model ± 0.3% of the full range + 0.5% of the measurement reading (turn down 1: 100).
  • Output signal: (analog) 0-20mA, 4-20mA, 0-5V, 1-5V, 0-10V or 2-10V
  • Output (digital) RS485 Modbus RTU, Lab View-Vls, Profibus DP-V0, DP-V1
  • Variations in pressure and temperature do not significantly affect the measurement
  • The real gas used for calibration
