Detection principle

The detector in the water supply pipeline is a powerful helper for the investigation and detection of the water pipeline. Using high-sensitivity hydrophone and high-definition camera unit, it can effectively detect various abnormal situations such as small leakage, damage, tube tumor, bubble, impurity deposition, etc., and transmit the detection situation back to the ground control unit in real time through the photoelectric composite cable connected to the tail. At the same time, with the help of the ground beacon system, accurate positioning of abnormal situations can be realized. Some pipelines are missing routing information due to their age, and this product can also be applied to achieve routing reconfiguration.

Other testing equipment

pipe spherical inner detector

The pipe spherical inner detector can detect and accurately locate the small leakage of the pipe. After the detector is put into the pipeline, it can roll along the pipeline with the flow of liquid. The sensor mounted inside it can collect the sound, acceleration, magnetic signal and other information along the pipeline, and effectively capture the pipeline leakage signal when the sphere passes through the leakage point. After the detector is recovered, relevant information such as pipeline leakage and pipeline direction can be extracted through the data analysis system, and the location of the leakage can be accurately located and the leakage magnitude can be estimated.
