C HAPTER 1 STAR ZONESCAN INSTALLATION Purpose & Scope This instruction outlines general practices and procedures for the installation of STAR ZoneScan leak detection MTUs.
Acoustic Leak Detection Overview Acoustic Leak Detection Overview Management of water leakage consists of four key activities which include: • measuring water loss • locating leaks • monitoring leakage • repairing leaks In order to understand leak noise, it is important to know the various sources of constant noise. Acoustic leak detection equipment collects and evaluates this noise to identify the probability of a leak.
STAR ZoneScan Installation STAR ZoneScan Leak Identification Process Data loggers are devices that continuously monitor and analyze leak noise in a water distribution system. They are attached to valve stems on water mains throughout the pipeline network. Each data logger is cable-connected to an Aclara STAR ZoneScan MTU that mounts on the underside of a non-metallic valve cover.
