d·flux Multi Series 2
Downloads
- Small | Compact Design
- Alarm Warning & Diagnostics
- High Flow Rates
The d-flux multi series 2 is high performance fast and reliable multi-parameter mass flow meter and controller 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.
This unique meter is also designed for optimum performance across a wide dynamic Min/Max flow range of up to 1000:1 (Available for meter only)
The d-flux meter / controller is also designed for installations with minimal upstream downstream piping installations
Features of the d·flux multi series 2:
- The unit is available as meter or with a integrated control valve (Controller)
- Flow rates up to 1400 ln/min (2900 ln/min Hydrogen)
- Multiple pre-programmed gases
- State-of-the-art communication
- Wide application scope IP54
- Wireless device access with the free Vögtlin Connect app(Android)
- Alarm, warning and diagnostic features
- High accuracy, sample rate and fast response
- Minimum Inlet required
- Custom application profiles
