ABSTRACT:
A leak detection system 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 is coupled to the valve in the pipe in-line with the fluid flow. A sensor couples to the flow and provides a signature output. A leak detector is coupled to the sensor and adapted to detect a leak through the valve based upon the signature output.
