Abstract
A pipeline tool includes a body, a magnet disposed at the body, one or more sensors disposed at the body, and a controller disposed at the body. The one or more sensors measure at least one force of attraction generated between the magnet and a ferromagnetic material of a tubular conduit. The controller performs operations which include determining, based on the force of attraction, a position of the pipeline tool within a cross-section of the tubular conduit relative to a wall of the tubular conduit within the cross-section.
