LEAK DETECTOR FOR PROCESS VALVE

摘要

A leak detection system (300) is described for detecting a leak through a closed valve disposed between an upstream pipe and a downstream pipe of an industrial process. An insertable plate (302) is coupled to the valve in the pipe in-line with the fluid flow. A sensor (316) couples to the flow and provides a signature output. A leak detector (324) is coupled to the sensor (16) and adapted to detect a leak through the valve based upon the signature output.
