A leak location measuring method and system for a fluid material pipeline, using a sensing delay of two points

摘要

A leak location measuring method and system for a fluid pipe are provided to estimate an accurate leakage location by using the measurement values of manometers and flowmeters installed in the fluid pipe. A leak location measuring method for a fluid pipe comprises a step in which a transfer constant according to the kind of fluid is input(S10), a step of estimating the density of fluid flowing in the fluid pipe and the location of the fluid according to kind(S20), a step of, when a leakage is detected at a spot, recording the leakage sensing time and senses a leakage at another spot(S40), and a step of, when the leakage is detected at another spot, estimating a leak location using the sensing time difference between the two spots and the transfer constant according to the kind of fluid(S50).
