FIELD: instrumentation.
SUBSTANCE: proposed instrument comprises interconnected power supply 1, locating and control unit 2 and set of magnetic pickups 3. Said set of magnetic pickups is composed of permanent magnets arranged radially in their crown to interact by their magnetic field with Hall transducer 302. Said instrument is displaced inside the pipeline, over its entire length, to control pipeline thickness and to detect whatever holes so that distance whereat detected holes are located starting from initial point is determined as well as their position in pipeline circumference. All measurements are a part of online process executed in instrument displacement inside said pipeline.
EFFECT: info can be loaded in computer to be available for use and decision making relative to pipeline integrity.
