  • Use as a meter, regulator, or switch
  • Measuring ranges from 25 mln/min up to 450 ln/min (27 SCCM – 480 SLPM)

Multi-Parameter Mass Flow Meter & Mass Flow Controller for Gases

The d·flux multi-series is a fast and reliable multi-parameter mass flow meter for gases with measurement outputs for mass, volumetric and normalized flow, pressure, and temperature. One of the many advantages of this laminar flow meter is the ability to easily switch to a different gas without a loss in accuracy.

  • Flow ranges from 0-350 to 0-1400 ln/min for air
  • Multi-parameter: measures 5 variables
  • Up to 15 gases/mixtures pre-programmed

  • Digital communication & analog signals
  • Advanced diagnostics & alarm output

Capillary Mass Flow Meters and Controllers (MFC) for Gases

The SmartTrak® thermal mass flow meters and mass flow controllers are true multi-gas digital MFC designed to deliver smooth, stable, accurate, and repeatable gas mass flow control you can rely on, every time.

  • Up to 0.5% full-scale accuracy
  • For corrosive and aggressive dry and clean gases
  • All wetted parts are stainless steel 316L
  • 10 pre-programmed gases, customer selectable
  • Operating pressure 35 bar
  • Measuring ranges from 4 mln/min up to 1000 ln/min

Thermal Mass Flow Meters and Controllers with IP67 & Ex Protection

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 are now available as IP67 / NEMA 6 version.

Pressure Controller for Gases with Integrated Flow Measurement

The electronic red-y smart pressure controller combines the reliable technology of our digital mass flow controllers with electronic pressure control. The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.

  • Pressure controller with flow measurement/limitation
  • Flow controller with pressure measurement
  • Pressure and back pressure devices
  • Analog and digital interface
