る水位センサ。 In a water level sensor, a water level sensor has a plurality of electrodes installed vertically from above the water surface in a manner perpendicular to the water surface and whose lower end positions differ from each other, and which detects the water level by changes in the resistance value between the electrodes. When both the lower end of the common electrode and the other electrodes are submerged in water, power is supplied to the electrodes so that electricity is passed through the water between the two electrodes, and the current is maintained between the two electrodes. A water level sensor is provided with a control circuit that recursively repeats an operation of stopping power supply to an electrode for a predetermined period of time when a certain condition is detected.
