Abstract: The present invention relates to a flexible tape (41;50) for use in detecting liquid leaks comprising an elongated substrate (44), having a length (L), a top surface (44a) and a bottom surface (44b), formed from a moisture absorbent material. The flexible tape further comprises at least one non-moisture absorbent electrically insulating material (45.46; 52) disposed on the top surface (44a), and first and second electrical conductors (47,48) spaced via the electrically insulating material (45,46; 52). The invention also relates to a leak detection system (80) and method for detecting a presence of an electrically conductive liquid.
