PIPELINE CONDITION MONITORING SYSTEM Russian patent published in 2017 - IPC F17D5/00 

FIELD: transport; valves production.

SUBSTANCE: invention relates to pipeline transport protection, intended for observation, detection and localisation of leakages, including from unauthorized tie-ins, as well as hydrate or paraffin plugs, and can be used in various branches of national economy. Pipeline condition monitoring system includes analogue-to-digital converter, to which are connected personal computer, hydraulic pulse generator as pulse excitation source located at beginning of controlled pipeline section, and intelligent pressure transducers in form of strain-gauge pressure transducers with built-in temperature converter, in which data from sensors in analogue-to-digital converter are converted into digital form with resolution to 0.001 MPa and sampling frequency to 1,024 Hz.

EFFECT: technical result consists in unauthorized pressure pulses improvement of accuracy and faster location, reduced time of detection and accuracy leakage point determining, as well as hydrated or paraffin plug in automatic cutting off broken down pipeline section, without waiting for dispatcher command.
