Abstract : The patent relates to a circuit for detecting the level of oil in an oil-collecting chamber containing oil floating on water. A pair of electrodes are disposed in the oil-collecting chamber for detecting the presence of oil therein. A sensing circuit, connected between the electrodes and an amplifier, contains a sensing current when water or air surrounds the electrodes. The amplified sensing current switches a transistor on transmitting a d-c voltage to an open type solenoid valve located in an outlet tube thereby closing the valve.
