摘要

Process for determining a leak in a pipe (4) for an electrically conducting fluid (6) comprises applying a first insulating layer (1) followed by a conducting layer (3) and a second insulating layer (2) on the inner wall of the pipe, and measuring the resistance between an electrode (7) in contact with the fluid and the conducting layer during the operation of the pipe. An Independent claim is also included for a measuring device for carrying out the process in the form of a Wheatstone bridge.
