Provided herein are a pipeline inspection system for effectively managing a pipeline by inspecting a state of the pipeline while moving along the pipeline. Moreover, the pipeline inspection system and the maintenance method using the same can improve scale removal efficiency by removing scale accumulated on the inner wall of the pipeline with ultrasonic vibrations, and prevent water leakage due to the corrosion of the inner wall of the pipeline.

An apparatus for measuring a position according to an embodiment includes a light source emitting light to an inner surface of a pipe, a first lens receiving reflected light from which light emitted by the light source is reflected by the inner surface and converting the reflected light into parallel light parallel to an optical axis, a second lens disposed on an optical path of the parallel light and converting the parallel light into a convergent refracted light, an image sensor disposed on an optical path of the refracted light, one or more elastic members disposed between the first lens and the second lens, and a plurality of wheels that are coupled to a side surface of the first lens and are in close contact with the inner surface to be rotated by movement of the moving body.

Systems and methods of the present disclosure relate to non-intrusive tracking or locating of objects in a conduit from a single location. A system comprises a vessel comprising a pressurized fluid, a valve positioned to control a flow of the pressurized fluid into the conduit to induce at least one pressure wave directed at the object, a pressure transducer in fluid communication with the conduit, the pressure transducer positioned to measure at least one pressure response in the conduit due to contact of the at least one pressure wave with the object, and a system controller operable to: receive pressure data from the pressure transducer, wherein the pressure data includes the at least one pressure response and determines a distance of the object in the conduit, relative to a reference point, based on the at least one pressure response.

Disclosed herein is a submersible having one or more sensors configured to collect a signal from an interior area of a liquid carrying channel, and a processor configured to obtain the signal from the one or more sensors, calculate a diameter and a circumference of the liquid carrying channel according to the signal. determine whether an irregularity is present on an inner surface of the liquid carrying channel according to the diameter and the circumference, and generate a notification to notify an irregularity has been detected on the inner surface.
