Mass Flow Sensors - d.flux multi series

  • The unit is available as meter or with a strong integrated control valve as controller.
  • Rate for air, other gases according to conversion (for instance hydrogen: up to 2900 ln/min)
  • Up to 15 gases can be pre-programmed in the unit.
  • Advanced Modbus communication & analog output. Optional: Profinet or EtherCAT interface (EtherNet/IP™ available soon).
  • Suitable up to 14 bar a and from -20 to 60 °C.
  • Compact design, requires no long straight or special inlet and outlet sections.

Add to compare
  • The d·flux multi series is a fast and reliable multi-parameter mass flow device for gases with measurement outputs for mass, normalized and volumetric flow, pressure and temperature.
  • The instrument is based on differential pressure measurement over an internal advanced laminar flow element.
  • One of the many advantages of this laminar flow device is the ability to easily switch to a different gas without a loss in accuracy.

Use Cases

  • Typically used in hydrogen and related industrial applications

Capabilities

  • Gas mass flow measurement (and control for controller variants) using laminar flow technology
  • Operation across wide pressure (1–14 bar(a)) and temperature (−20 to +60 °C) ranges
  • Multigas operation with rapid gas switching without loss of accuracy
  • Digital and analog communication for industrial system integration
