Well, my AQ flow meter has started reporting 0 gpm flow rate. The water definitely still flows fine. If I drop the pumps extremely low, and manually zero out the pumps, its possible to get a raw value of approximately 8.
It's probably going to take a few days for AQ to get back to me. In the mean time is there anything I can do to try to revive the meter? Maybe, cut the power to the pumps to try reseting the zero point? (auto zeroing during stand by doesn't seem to be happening)
