Documented Cases
The
Acoustic Leak Locator (ALL™) has been in service since 1991, with the original
installation at Alabama Power Company’s Gaston Station. Since then, over 90 different
locations in 10 countries have installed the ALL™ system, with over 2,000 sensors in
service.

Main steam line leak detected before penthouse was damaged
STEAM LINE MONITORING
Internal valve leak discovered 3 months prior to any audible/visible warning
Valve repaired during scheduled outage – saved on replacement power

FEEDWATER HEATERS
CISE (Italy)
Experience has shown that monitored FW heaters have only 1 or 2 leaking tubes
