Abstract

A sensing system measures a potential gradient from a damaged location 11 of an anti-corrosion layer of a buried pipeline 10. The damaged location creates a field 12 which is measured by first and second probe rods 100, 200. The probe rods are connected together by a cable 300. The first probe rod measures a first AC and/or DC potential at a first location; the second probe rod measures a second AC and/or DC potential at a second location. The difference between the two potentials at each location is calculated to measure a gradient. The probe rods are moved (figure 3) along the pipeline to locate the damaged region. The probe rods also include positioning means, such as GPS. Data is transmitted from the probe rods to a remote mobile terminal. The invention uses just two probe rods to measure AC and DC gradients instead of separate devices for measuring AC and DC.
