Unless something has changed, the flow meters really just establish a baseline, then alert if current running rate thresholds do not meet. So it doesn’t matter if your meter is reading correct GPM. I’m not sure where the gallons/month comes from, but I thinking its from the baseline, not the actual readings multiplied by minutes ran. There certainly seems to be rounding errors, as when I run for like 20seconds, I get 1 minute of usage shown.
