Page 11: Chapter 2 Principles Of Leak Noise Correlation
ADS Eureka Digital System User Manual C H A P T E R 2 Principles of Leak Noise Correlation Leak noise correlation is used to detect leaks in pipes with a positive internal pressure, where leaks allow a loss of flow to the outside. The movement of fluid through the leak causes rapid pressure changes around the site of the leak, establishing a noise source at the leak. -
Page 12: Methods For Locating Leaks
ADS Eureka Digital System User Manual Methods for Locating Leaks Previous methods of leak location relied on an initial detection of a noise, which was then traced along ground level to identify the location of the maximum noise. This location was assumed to be directly above the location of the leak. - Page 13 ADS Eureka Digital System User Manual pipe under investigation, ensuring the greatest accuracy in locating the leak.
-
Page 14: Sensor Position
ADS Eureka Digital System User Manual Sensor Position Correlator operation relies on the location of the leak existing between the two sensors. However, two contexts can prevent this from occurring. The solution requires moving one sensor before a successful correlation can be performed. -
