Abstract: The invention proposed here discloses an instrumented PIG that uses a sufficient number of sensors for detecting the NORM of the scales, variation in the thickness of the scale deposit, internal diameter and detection of the internal position of the beginning and ending of these along the piping. The modular form of the NORM instrumented PIG (1) provides enough flexibility to the invention to allow the passage in curves and ability to tolerate variations in diameters. The system has a mechanical design in which the sensors are mounted on rubber modules, interconnected with each other, forming a mechanically flexible assembly.
