I don't know that that eventuality is likely enough that one should go to so much trouble. What if someone overfills? What's the worst that happens? A puddle on the floor. You mop it up and are more careful next time. (Okay, maybe someone has a priceless Strad on the floor under the piano and it gets ruined. Lots of things are conceivable, but hardly likely). Of course, if the indicator were a light instead of an audible (which presumably would give off only one or a short series of beeps), the light would say it was full until the level fell below the probes.
