PRECISION GAS FLOW METERS & GAS FLOW CONTROLLERS

Multi-Parameter Mass Flow Meters & Mass Flow Controllers 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.

Meter and Controller

The unit is available as meter or with a strong integrated control valve as controller

Flow rates up to 1400 ln/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

State-of-the-art communication

The devices offer advanced Modbus communication & analog output.
