Applications/Examples of results
●Example of I/O Options ■Control of Shut-off Valve →The ON/OFF output from pin 5 of the D-sub 9-pin connector can be used to operate the shut-off valve. ■Pulse Output →You can enable the function to output flow at a user-defined frequency to an external device from pin 5 of the D-sub 9-pin connector. The pulse output can be directly supplied to external integrators, digital indicators, control instruments, etc. ■Cumulative Flow Reset Function →The EL-FLOW Prestige comes standard with alarm and counter functions. If the cumulative flow is displayed on a local R/C module like BRIGHT, it needs to be reset via button operation on the display. Alternatively, if you assign the counter reset function to pin 5, it can be reset by an external signal. *For more details, please contact us or download the catalog.
