It is used to detect pipeline passing ability before pipeline deformation detection or pipeline magnetic flux leakage internal detection, so as to prevent blockage and detection safety accidents of magnetic flux leakage internal detector.

Function:Ultra high definition detection capability exceeding 10m/s, accurate quantification of pipeline defect characteristics.

Configuration：Power section, detection section, mileage section, battery, low-frequency transmitter, receiver, inertial navigation system (optional), and internal stress detection (optional).
