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

D-flux Multi Series

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.

  • Suitable for most common gases.
  • Flow up to 1400 In/min (Air).
  • Pressure up to 14 bar.
  • Options: All stainless-steel, high accuracy, gold plated sensor for hydrogen.
  • Vögtlin Connect App: can works with Bluetooth®


Flow rates up to 1400 In/min

  • The unit is available in 4 ranges (0-500, 0-700, 0-1000 and 0-1400 ln/min for air). Each range can be reduced by the user by 30% without any loss in accuracy (rate for air, other gases according to conversion)

Multiple pre-programmed gases

  • The d⋅flux multi series mass flow instruments can contain up to 15 programmed gases. More gases can be added at any time.


  • The devices offer advanced Modbus communication & analog output.
  • Optional Profinet or EtherCAT interface available (Ethernet IP available soon)

Wireless device access with the free Vögtlin Connect app

  • The Vögtlin Connect app can be used with any Android phones and lets you easily and securely (password protected) connect to your d·flux device. Vögtlin Connect is a user-friendly configuration software and offers the adjustment of many device parameters.
