Documented Cases – The Acoustic Leak Locator

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.
