Abstract: A leak detection system capable of automatically detecting a leak in a pressurized piping system. A pressure decay test is utilized to test for leaks in the piping system. Disruption to users of the piping system is reduced by only performing the pressure decay test when there is no user demand on the piping system. Thus, a leakage test is performed by first determining whether there is user demand on the piping system and proceeding with a pressure decay test only if there is no user demand present. If user demand is initiated during the performance of a pressure decay test, the system detects the user demand and halts the pressure decay test until the user demand stops.

Abstract: The present invention provides a system and method for detecting changes in the properties of a polymeric material. A frame is hand held against the outside surface of a curved polymeric test specimen, e.g., fluid tank. A transmitting probe attached to the frame emits critically refracted ultrasonic waves that travel longitudinally across the chord of said curved test specimen and are detected by at least one receiving probe attached to the frame. A data processing system measures the travel time of the ultrasonic waves from the transmitting probe to the receiving probe and compares this measured travel time to an expected travel time. Variations in material properties along the penetration path of the ultrasonic waves can be detected from deviation in the measure travel time of the waves from the expected control values. Measuring the temperature of the polymeric specimen allows adjustment of the measured travel time of the waves to account for temperature effects on the polymeric material.

Abstract: An acoustic energy-based, non-contact or contact testing approach provides low cost, highly accurate, and reliable information to (a) identify flaws and anomalies and (b) assess the integrity of a particular material.
