Principles of Operaton
Two aluminum foil pads are glued to each tank.
A small high frequency
alternating voltage is passed to one of the pads.
A radio sig _
capacitivity coupled to the other pad.
The radio signal is passed back up
toPthe panel where it is electronically converted to a direct voltage w i
drives the LED readout.
That is the mechanism by which water level is sensed through the walls of
thetaL
The radio signal (and the readout) is proportional to the area of
the aluminum foil pads" covered by water (on the other side of the tank
wall).
Therefore, if the pads are installed correctly the lead
proportional to the water level in the tank.
