Is there any way to get a live gpm reading other than re-doing calibration?
I ask because I’m debugging fluctuations in my irrigation (e.g., periodic low-flow warnings) and if I go to re-run a zone manually because I had a low-flow, I have no idea what the flow of that run actually is.
Fwiw I suspect that my water pressure is lower in the morning because I seem to get low-flow warnings whenever it runs automatically, but if I run manually it seems fine. Then again without re-running calibration I cannot be certain every time.
My other hypothesis is because I use drip lines, the hoses may be more pliable in the day than at 4am, which is pretty much the coldest point in the day. That might cause them to emit less, though I’m getting a reduction of 2/3 to 3/4 of the expected flow, which is more than I’d expect.
