an easy fix? (blind) humidifier filling

[Mark Cramer]

It occurs to me there may be a simple(r) solution to "blind" filling of
humidifiers in grands with bottom covers, but I honestly need some feedback
from the tinkerers among us to know if it's worth pursueing:

Note that you can often hear the water "trickling" into the tank until the
level rises above the end of the hose.

Stop the flow of water before the hose-level is reached, and the "trickling"
stops.

While pouring until the hose is almost submurged, then stopping, will cause
a "gurgling" sound, as air enters.

Filling beyond this point is silent (until the tanks overflows) however,
when you lower the pitcher, the water-flow will reverse.

So it seems several "audible" indicators of water-level already exist,
without a need to "manually" check the tank.

One difficulty however seems to be "hearing" the trickling sound, and
noticing when it stops. The sound is often very faint.

I'm wondering if some really, really simple fixture could be added to the
end of the hose to make the "trickling" sound LOUDER, more distinct?

If so, our watering assistants could merely add water to EVERY piano, by
schedule, rather than demand.

They could add water until the "trickling" sound stops.

If the tanks were still full, there would be no "trickling" sound, and air
would "gurgle" back when they stopped pouring.

If over-filled, the pitcher could be lowered to siphon excess water back,
until the "gurgling" sound indicated capacity.

One point Becky Baldwin of Dampp-chaser mentions, is the need for the angled
slice at the end of the water hose, and that this be set precisely for
correct water-level. (sorry, I forget)

Anyhow, wouldn't it be nice to face the return of students in fall with this
deceptively simple problem solved?
