METHOD OF DETERMINING LEAKAGE SITE IN PIPELINES Russian patent published in 2004 - IPC

Abstract RU 2234637 C1

FIELD: protection and supervision of pipe-line systems.

SUBSTANCE: method includes recording time of coming two shock waves of lowered pressure generating at the moment of the local breaking down of a pipe line, calculating the time difference of the coming shock waves, determining the site of leakage, generating high-frequency oscillation at the moment of the local breaking down, control of its phase with a modulating code, which comprises information on the number of emergency pipeline segment, and, thus, generating the alarm signal.

EFFECT: enhanced reliability.
