I have a well with a 3/4 HP submersible, and the difference in current when under load and the "run dry" case is too small to allow a good set point to trip the controller. If I ever have to replace the pump, I'll size it correctly so the contrast between normal load and run dry is more reasonable. Right now, the difference is ~ .2 amps (from 6.5 -> 6.3).
Does anyone know of an existing device that works on the actual flow where once flow drops off, it signals a shutdown timer which keeps the pump turned off for the selected time delay? I can buy a flow meter, and build a circuit that does this, but would rather buy something off the shelf where others have already worked out any issues.
