EL-FLOW Prestige Series, Mass Flow Meters and Controllers

EL-FLOW Prestige Series, Mass Flow Meters and Controllers

Product Overview

EL-FLOW Prestige Series is the latest generation of thermal mass flow meters and controllers for gases, representing 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. 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:

  • Lowest range 0.014…0.7 mln/min
  • Highest range 2…100 ln/min

Why choose pressure insensitive gas mass flow controllers?
External factors can have 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.

Applications

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. 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: 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.
