Method and apparatus for identifying and locating a leak in the inner liner of a vessel having a laminated wall structure

Abstract From the Canadian patent

A vessel for containing an electro-conductive fluid the vessel having a laminated wall structure and including an outer structural shell, an inner corrosion-resistant lining made of electrically non-conductive material constituting a barrier between the structural shell and electro-conductive fluid in the vessel. An electrically resistive medium is mounted between the structural shell and the corrosion-resistant lining, the resistive medium carrying an array of electrodes mounted in spaced apart relationship at fixed and known locations. A main electrode is mounted in the vessel extending into the electro-conductive fluid which forms an electric path between the main electrode and the …
