Abstract: A conductive fluid leakage sensor capable of detecting a leak from a first electrically conductive or non-conductive container with a conductive liquid disposed therein, has a second or outer electrically conductive coating surrounding a first conducting or non-conducting inner container. An electrical connection is made between the outer member and to the conductive fluid disposed within the container, so that conductive fluid leaking from the container that comes into contact with the outer electrically conductive coating creates a pulse, which may be sensed by a sensing apparatus providing an indication thereof.

Abstract: A water leakage protector apparatus for appliances subject to leakage includes a first device for detecting water leakage from the water supply line coupled to the appliance and a second device for detecting water leaking from the appliance itself. A control apparatus is coupled to a valve, affixed to the water supply line, is connected to a source of electrical power, and controls the water flowing to the appliance. The appliance is connected to the control apparatus to obtain electrical power for operation. The first and second sensing devices are coupled to the control apparatus so that when a water leak is detected by either the first or the second detecting device the control apparatus stops the water from flowing in the water supply line and interrupts electrical power to the appliance.
