'Detection principle and method'

Probing, direction finding, sounding principle
The transmitter sends a specific electromagnetic wave signal to the underground pipe and determines its position, direction and depth by detecting the magnetic field of the underground pipeline.
Leak detection principle: the transmitter to the underground pipeline to send a specific electromagnetic signal in the underground pipeline coating damage point and the earth to form a loop, and radiation to the ground, above the damage point is a strong radiation signal, according to this principle to find the pipeline Corrosion point of the coating.
Leak detection method: We use the 'human capacitance' method. It is to do with the human body sensor detector components along the pipeline to detect, when the detectors went near the leak, the detector began to react, Just above, the speaker of the sound, the value shows large, so as to accurately find the leakage point.
