METHOD OF WARNING ON BREAK IN PRODUCT LINE Russian patent published in 2004 - IPC

Abstract RU 2230252 C2

FIELD: monitoring and check of underwater and underground product lines. SUBSTANCE: proposed method includes supply of sounding signal and estimation of results of sounding ; used as sounding signal is optical pulse signal sent over at least one measuring channel isolated from surrounding medium; for forming such signal, envelope of product line is fastened with fibrous light guide; it is good practice to make is continuously over entire length of section under test; break is demonstrated by change in parameters of reflected optical signal at measuring channel input. EFFECT: possibility of monitoring product lines; enhanced efficiency. 2 cl, 1 dwg
