Water supply control and leak detection device - switches off water supply to equipment when leak occurs by using water-detecting electrodes to operate relay closing solenoid valve

摘要

The device has a water-sensitive detector acting on an electrical device that operates an electromagnetic valve in the water supply line. The detector operates a relay in the valve circuit and is located at the lowest point in the room in which the equipment is situated or in the equipment itself. The detector consists of two metal electrodes sandwiching a material porous to water. The electrodes are coaxial tubes. The porous material is porous paper or cotton like material. The detector turns on a transistor switch that operates the relay.
