EL-FLOW® Prestige Mass Flow Meters / Controllers for gases

The High Performance MFM / MFC That Adapts To Your Process

EL-FLOW® Prestige, the latest generation thermal mass flow meters and controllers for gases, represents a truly ground-breaking shift in versatility and user-friendliness. Its principal customer benefits are based upon further advance in flow-signal processing and a highly stable flow control regime that is virtually impervious to process fluctuations.

Furthermore the Prestige is equipped with an advanced control valve design and an on-board gas conversion model. Other improvements are a significantly reduced power consumption and a user configurable device with a multitude of additional features and benefits.

  • Lowest range 0,014...0,7 mln/min
  • Highest range 2...100 ln/min

The Mass Flow Meter/Controller that adapts to your process

The control performance of EL-FLOW Prestige Mass Flow Controllers is factory adjusted to swiftly respond to setpoint changes, without overshoot. Moreover, the controllers are highly resistant to mechanical shocks and pressure fluctuations, which may be caused by other devices consuming gas from the same source. As an option the MFCs can be tuned for extra fast response (settling times t98% down to 500 msec) or extra smooth control, depending on the requirements of the user’s process. The dynamic behaviour can also be tuned on site easily, by adjusting the controller speed settings via FlowTune™, or by using our software tool FlowPlot™. This free tool can also be used for device diagnostics or alarm and counter settings.

Select the I/O options of your preference

Numerous input/output options can be offered through the programmable sub-D 9-pin connector. In addition to the various analog signal options and the standard RS232 communication, there are such options as RS485 communication, digital frequency/pulse output, alarm output/reset, valve purge/close and analog valve output. Furthermore Bronkhorst offers various integrated fieldbus options: DeviceNet™, PROFIBUS DP, PROFINET, Modbus RTU/ASCII, EtherCAT® and FLOW-BUS. The latter is an RS485 based fieldbus, specifically designed by Bronkhorst for their mass flow metering and control solutions. For the convenience of customers working with LabVIEW™ (graphical software by National Instruments) Bronkhorst provides a certified plug & play instrument driver for instruments with FLOW-BUS™ interface.

Reduce your cost of ownership

EL-FLOW Prestige offers high flexibility due to the Multi Gas / Multi Range (MG/MR) functionality. This functionality, now extended to 25 gases, is easily accessible via the FlowTune software or PLC; there is no need to disconnect the instrument from your system. For additional gas types the user can calculate accurate fluid properties for conversion by means of our free, online software tool Fluidat® on the Net. Users of EL-FLOW Prestige instruments can rescale their instruments on site, saving time and money for dismounting and recalibration. Furthermore, original equipment manufacturers (OEMs) are able to drastically reduce the variety of spare instruments kept on stock and thus reduce the cost of ownership.

Customized Input/Output configurations

Besides the obvious I/O-options for measured and setpoint values via analog signals, RS232 or fieldbus communication, EL-FLOW Prestige features a programmable pin (pin 5) at the 9-pin sub-D connector for customized I/O configurations. This functionality can be used for advanced operations such as digital frequency/pulse output, alarm output/reset, processing an external setpoint signal, valve purge/close and analog valve output. Some options are specified in the model number identification, however, numerous other settings can be programmed on request.
