TS-GD200SThe pipeline sonar detection system is mainly used for detection of water-containing pipes (full of water or a water level greater than 2/3), inspection wells or underground cavities, automatic analysis and extraction of inner wall contours to establish three-dimensional models for quantitative analysis. When used for pipeline detection, it can accurately identify most structural defects (rupture, deformation, dark connection of branch pipe, disconnection, etc.) and functional defects (sedimentation, obstacle, residual wall, dam root, etc.), automatically measure the siltation volume and generate longitudinal section diagram of the sedimentation state of pipe bottom. By matching expansion parts, the system can be combined with CCTV for comprehensive detection (abovewater and underwater). The sonar probe has a rotatable ultrasonic transducer that projects acoustic waves onto the wall of the pipe and receives the echoes. The transducer can complete 360-degree continuous scanning within 1 second; each 360-degree scan will have 400 transmitting/receiving cycles with a field angle of 0.9o, and each transmitting/receiving cycle samples 250 points.
