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

Vögtlin have released the dflux multi series mass flow meter for gases. The dflux  is a fast and reliable multi-parameter device 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.

Core Features:

Meter and Controller
The d⋅flux from Vögtlin is available as meter or with an integrated control valve as controllerFlow rates up to 1400 ln/min
The d⋅flux Flow Meter 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 timeState-of-the-art communication
The devices from Vögtlin offer advanced Modbus communication & analog output.
Modbus Interface for our Mass Flow Devices Profinet RT Interface for our Mass Flow DevicesEtherCAT Interface for our Mass Flow Devices
Optional Profinet or EtherCAT interface available (Ethernet IP available soon)Wide application scope IP54
The d⋅flux multi meters and controllers are suitable up to 14 bar a and from -20 to 60 °C.
The body is in stainless-steel 316L and environmental protection is IP54Wireless device access with the free Vögtlin Connect app
The Vögtlin Connect app can be used with any Android phones and let’s 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
d·flux multi series Mass Flow Meter for Gas with Connect AppAlarm, warning and diagnostic features
The d·flux multi series integrates advanced diagnostics, monitoring and reporting every part of its operation. The information is accessible via Vögtlin Connect app or Modbus

High accuracy, sample rate and fast response
Accuracy is ± 0.5% of customer full scale and ± 1% of measured value. Sample rate of 1 ms, updated data every 10 msec and a total response time of 90 msec (controller 2s)

Minimum Inlet required
Compact design, requires no long straight or special in and outlet sections

​Custom application profiles
The unit offers up to 15 application profiles which allow the storage of individual application details

Introducing Vögtlin Automated Dynamics VADy®
With the d·flux multi series, Vögtlin for the first time introduces an automatic real-time calculation of the optimum dynamic range*.

With this user selectable setting, the device dynamically adjusts the highest possible dynamic range under actual conditions. VADy® makes it easy to work with the different gases and applications and offers convenience with optimum device efficiency:

Default dynamic range 1 : 100
1 : 1000 dynamic with VADy® feature available
