FIELD: measuring equipment.
SUBSTANCE: not less than one calibrating member made of the plastic material is made a component of the construction of the pig. Not less than one bending resistor is mounted on the calibrating member. In another version of the invention, not less than one bending resistor is installed in the elastic member, which is attached to the calibrating member from the pressure delivery side in the pipeline. The recording equipment unit, which makes measurements and mounted resistors indication record, is also inserted into the pig. The calibrating member bends while passing the narrowing. The bending resistor (s) also bend (s). The bending resistor (s) change (s) its resistance in consequence of the bend, which is registered by the equipment. The received data are analyzed after the removal of the pig.
EFFECT: device operational characteristics enhancement, its performance reliability growth.
