ABSTRACT:
A method and apparatus for detecting and locating fluid leaks, particularly liquid leaks, and determining whether the leaking liquid being detected is a non-conductive liquid such as a hydrocarbon or a conductive liquid such as water utilizes a composite detection cable having a pair of insulated conductors and a pair of uninsulated conductors. Pulses are applied to the insulated conductors and leaks are detected and located utilizing time domain reflectometry (TDR) techniques. The resistance between the uninsulated conductors is measured to determine whether or not the leak is conductive.
