So it’s clear, too many pulses and the flow count (2582 in my example?) is or may be off. I will experiment with a 10 to 1 frequency divider.
But what about the math:
First email: “Station XYZ closed. It ran for 2 minutes 0 seconds. Flow rate: 1363.91”
Second email: “Flow count: 2852, volume: 85.56”
Whether 2852 is wrong or not, where are 85.56 and 1363.91 coming from? Irrigation time was 120 seconds.
