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.
Claims9
A collecting conduit for leakage monitoring and leakage location at an installation, the collecting conduit comprising:
- a support pipe having openings, an outer surface, an interior and a longitudinal direction;
- a layer being permeable to a substance to be monitored and allowing the substance to pass into said interior of said support pipe through said openings, said layer covering said outer surface of said support pipe, at least on a segment extending in said longitudinal direction of said support pipe;
- and
- an electrically conductive layer into which the substance can at least penetrate, said electrically conductive layer extending in said longitudinal direction and having an ohmic resistance depending on the substance penetrating into said electrically conductive layer.
