Thermal Mass Flow Meter with Fast Response to Improve Performance
The control performance of EL-FLOW Prestige Thermal Mass Flow Controllers is factory adjusted to swiftly respond to setpoint changes, without overshoot. Moreover, this low flow meter/controller 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.
