Watering Dampp-Chaser Systems in University Pianos

[Ed Sutton]

For institutional use, why not just have a humidifier pan with the tube
leaving the bottom, then connect the tube to a filler/gauge cup which is
attached to the outside of the piano with its lip at the same level as the
rim of the pan? No electronics at all.  Fill until the water level reaches
the top of the cup and the pan is also full.
This would also lower the cost of practice room systems by the cost of the
electronic monitor lights and feelers.
