This powerpoint presentation begins by providing a brief overview of correlation: bracket the leak with two sensors; the leak noise takes longer to arrive a point 1 thanpoint 2; and, correlator measures this difference and determinesthe exact leak location d=vt where v is the acousticwave velocity. A brief overview of trunk main leak detection is presented, along with recent case studies on large diameter truck mains.
