LEAK DETECTOR Abstract of the Disclosure A leak detection system and a method of detecting leaks are disclosed for detecting a leak in a system. including A pump, a dispenser, a conduit communicating the pump and the dispenser, and a valve in the conduit. The valve includes an electronic flow measurement device for detecting leaks in the system downstream of the device. The system may be operated by a control circuitry, which indicates a predetermined flow of fluid indicating a leak. The present invention is also directed to a method of detecting a leak in a system having a fluid pump, a dispenser, a conduit connecting the pump and the dispenser, a valve in the conduit, and an electronic flow detection system in the valve. The valve is provided with an orifice communicating the conduit with the electronic flow detection system. The method includes the steps of activating the pump and opening the dispenser to dispense a fluid, and then closing the dispenser while continuing the activation of the pump thereby increasing fluid pressure in the conduit. The increase in fluid pressure causes the valve to close, thus isolating the pump from the dispenser except for the orifice in the valve. The electronic fluid detection system senses the flow of fluid through the orifice.
