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.
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.
