FIELD: technological processes.
SUBSTANCE: application: in methods and devices for determination of clogged areas in pipeline. Method consists in the fact that time of change of measured pressure and temperature values to border values is measured both during pumping of working substance from device of working substance supply and in case of its cessation. Distance to clogged area is defined from mathematic dependence. Device comprises device for working substance pumping and pressure detectors. This device also has temperature detectors and control unit, which provides for reading of pressure values and working substance temperature values, and also measurement of time of pressure and temperature variation both during pumping of working substance and in case of its cessation.
EFFECT: increased accuracy of clogged area detection in pipeline.
