Description

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.
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 IP54
Wireless 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
Alarm, 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

*available for meter only

More gases can be added as options.²
	¹ Unless clearly stated, the specified flow ranges are for an equivalent flow of air at 1013.25 mbar a (760 mmHg) and 0 °C (32 °F). Other common flow, temperature and pressure units can be selected through the Vögtlin Connect app or the digital communication interface. More information available in the d·flux multi operating instructions. ² Additional gases or gas mixtures can be added to the above standard list. Maximum you can store up to 15 gases per unit. Stored gases can be replaced by another gas or gas mixture (except for air). Programmed gases/mixtures can be selected through the Vögtlin Connect app or the digital communication interface. For other gases, gas mixtures and reference conditions please contact the factory. Only suitable for dry and clean gases.
