ã€Detection principle and method】
Principles of sounding, direction finding, and sounding The transmitter sends a specific electromagnetic wave signal to the underground pipeline, and determines its position, direction, and depth by detecting the magnetic field of the underground pipeline.
Leak detection principle: the transmitter sends a specific electromagnetic wave signal to the underground pipeline, forms a loop with the ground at the damaged point of the underground pipeline anticorrosion layer, and radiates to the ground, the radiation signal is strongest directly above the damaged point, and the pipeline is found according to this principle Damaged point of anti-corrosion layer.
Leak detection method: We use the "human body capacitance" method. It uses the human body as the sensing element of the detector to detect along the pipeline. When the inspector walks near the leakage point, the detector starts to respond. When it walks directly above the leakage point, the sound in the horn is the loudest and the value shows the largest. , So as to find the leakage point accurately.
