FIELD: machine building.
SUBSTANCE: device refers to checking and measuring systems. The device consists of sensor 6 for determination of hydro-static pressure of liquid medium, also the sensor is mounted on a middle one out of three hinge-jointed pontoons, further, the device consists of snake line 4, and of control cable 7. Hydro-static pressure of water inside the pipeline is measured in specified intervals of pipeline length. Thus, there can be calculated vertical angles of a pipeline section and there can be plotted a lengthwise profile of the route.
EFFECT: possibility to measure vertical angles for determination of lengthwise profile of route of submerged underground pipeline.
