When the light stops flashing, that is the point at which the tank is exactly one full watering can low. Stop filling, go fill the watering can back up to the fill line and finish filling the tank. Fool proof. No digital sensing devices needed. Of course, right now, I only have the units in teaching studios and the profs will fill the tanks as soon as the lights come on because under the bass edge of the keyboard the flashing lights are distracting to the player. (and even in these high humidity summers the tanks need filling more often than every two weeks -- more like a week to 10 days.)
