Detector for measuring trajectory and depth of non-metallic pipes, buried under earth, comprises pipe, which flows liquid, and pipe is connected with generator of alternating current voltage

摘要

The detector comprises a pipe, which flows liquid, and the pipe is connected with a generator of alternating current voltage, where the generator is connected with earth and a magnetometer, and the magnetometer is movable on the surface of the earth. The magnetometer measures different points of magnetic field around the pipe.
