Hi All, I am using 1214C S7-1200 PLC. I have paddlewheel flowmeter right now I am counting number of pulses with HSC(High speed counter) and dividing them by K Factor to get flowrate in GPM however the pulse duration from the Flow Meter changes constantly based on the flowrate what should I set my input filter value to (see attached) so that it can capture the the pulses for every flow rate. IP800 | Seametrics Please share some guidance How I can make this work. |

Go to your s7-1200 PLC's digital inputs. For the digital input used for wiring and connected to the HSC, change the filter settings on that DI to the fastest filter so you do not lose pulses. I *know* it should not matter, but it has always mattered for these HSC inputs ever since the first s7-1200 PLCs.
