Abstract
A collecting conduit for leakage monitoring and leakage location at an installation, includes a support pipe having openings. An outer surface of the support pipe is covered by a layer being permeable to a substance to be monitored, at least on a segment extending in longitudinal direction of the support pipe. An electrically conductive layer extends in longitudinal direction. The substance (L) can at least penetrate into the electrically conductive layer and the electrically conductive layer has an ohmic resistance dependent on the substance penetrating into it. An apparatus and a method for leakage monitoring and leakage location are also provided.
