A leak location measuring method and system for a fluid material pipeline, using an intersection of pressure lines

摘要

A leak location measuring method and system are provided to estimate a leak location of a fluid pipe from pressure values easily by obtaining straight lines that the pressures measured at two sides of the leak position are extended and determining the intersection point of the straight lines as leak location. A leak location measuring method comprises a step of obtaining pressure correction values at A spot and B spot within a fluid pipe, a step in which pressure values are input from manometers installed at four spots when a leakage occurs between the A and B spots(S11), a step of searching for the location in which a straight line connecting the pressure of S spot and the pressure of A spot and a straight line connecting the pressure of D spot and the pressure of B spot meet(S12), and a step of determining the location as a leakage location(S13).
