The MISTRAS Triple 5's Acoustic Monitoring System (AMS™) provides early tube leak detection on pressurized vessels such as gas fired power boilers, recovery boilers and feedwater heaters. The AMS™ technology has been used in conventional power boilers for more than 25 years and provides 24-7, real-time data that detects and tracks the progression of tube leaks. AMS™ listen for changes in normal boiler background noise, a rise in which indicates a leak. Those acoustic monitoring capabilities via the AMS™ provide early indication of tube leaks well before traditional plant methods, which reduces secondary damage and informs plant personnel in making any number of operational, market, and outage decisions.
