We’ve had a rainy winter in the SF Bay Area. This morning was the first time the sprinklers ran in months. It was also the first time they ran since I installed two wireless flow meters.
The run was short lived as the zone shutdown with a high-flow. When I tried the zone manually, I saw no problems. It shutdown because:
“We detected a flow rate of 4.8 gpm, which is above your set threshold of 3.4 gpm.”
I recalibrated the zone and all the other zones. All recorded as higher. Only one, 8.0 -> 8.1, was a very small change.
I suppose the water pressure could be higher than when I first tested. I also suppose I could relax the alarm from 110% of flow to something higher.
The pressing issue I have is what I saw when I calibrated. During calibration for every zone (which means zones in two separate flow meters), the rate shown alternates between 0.0 and the actual flow. The two attached photos illustrate the issue. These two photos are in zones controlled by separate flow meters. (Sorry about that volume display in the second photo.)
Are others seeing this behavior when calibrating? I can’t compare to when I calibrated in late December as I believe there was no continuous readout of flow in the app back then.
