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 a further advance in flow-signal processing and a highly stable flow control regime that is virtually impervious to process fluctuations.
EL-FLOW Prestige is equipped with an on-board gas conversion model, including a gas database for 100 unique, customer selectable gases. Flow ranges, based on N2 :
and many more!
Fast response to improve performance
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.
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: CANopen®, 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 100 gases, is easily accessible via the FlowTune™ software or PLC; there is no need to disconnect the instrument from your system. 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.
Why choose the option of pressure insensitive gas mass flow controllers?
External factors can have an influence on the measurement accuracy and control stability of mass flow controllers (MFCs). EL-FLOW Prestige instruments feature accurate temperature compensation, correcting the flow measurement for temperature changes. Compensation of pressure changes can be achieved by using the new ‘Pressure Insensitive’ option instead of using an external pressure transmitter.
