'Detection principle and method'
Positioning sounding principle: the use of electromagnetic induction principle, through the detection of underground metal pipeline magnetic field distribution to determine the exact location of the underground pipeline, direction and depth.
Anti-corrosion layer leak detection principle: through the transmitter to the underground metal pipeline to send an electromagnetic signal, when the underground pipeline corrosion insulation layer there is a break point, where the short circuit with the earth, resulting in leakage current to the surrounding radiation, and above the radiation point of damage Strong, according to this principle to find the pipeline corrosion insulation layer of the damaged point.
