Multi-Parameter Mass Flow Meters & Mass Flow Controllers for Gases

The Vögtlin dflux Multi Series is a fast and reliable multi-parameter mass flow meter for gases with measurement outputs for mass, volumetric and normalised 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.

Features of the dflux Multi Series:

  • The unit is available as meter or with a strong integrated control valve as controller
  • Flow rates up to 1400 ln/min
  • Multiple pre-programmed gases
  • State-of-the-art communication
  • Wide application scope IP54
  • Wireless device access with the free Vögtlin Connect app
  • Alarm, warning and diagnostic features
  • High accuracy, sample rate and fast response
  • Minimum Inlet required
  • Custom application profiles
  • Introducing Vögtlin Automated Dynamics VADy®
