  • Acoustic leak detection system
    Patent number: 5231866
    Abstract: An acoustic leak detection system comprises a sensor array, data acquisition unit, and computer analysis of detected leak signals. Sensors are arranged in a small array about the base of the storage tank and provide signals to the data acquisition module which are digitized and analyzed to compute spherical coordinates of detected signals for all permutations of sensor positions and signal arrival times for forming a vector indicative of the signal path.
