The application of a continuous leak detection system to pipelines and associated equipment

Abstract

An overview of classical leak detection systems is given and the engineering basis of a novel type of detector is examined. This system is a flexible hydrocarbon-sensing cable that can be installed along pipelines, in double-containment tanks and piping, or in trenches to detect and locate leaks of common industrial hydrocarbon solvents or fuels while ignoring the presence of water. The simple electrical circuit that locates and detects a leak anywhere along the length of the sensor is also described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
