摘要：A water level controller for a tank has control circuitry and multiple

conductance terminals connected to the control circuitry and located at different heightsfrom the other. By such an arrangement, the water level can be determined when the

conductance of the water measured by corresponding conductance terminals becomeszero. The water inlet can be controlled to add to the tank by the control circuitry as theconductance measured by two of the corresponding terminals becomes practicallynegligible. Consequently, the water level in the tank can be accurately controlled, andthe controller can be used with pure water so as to enlarge the useful scope of thecontroller.
