PROBLEM TO BE SOLVED: To disclose a pressure relief valve monitoring system and method. SOLUTION: The online pressure relief valve monitoring system 100 includes at least one acoustic sensor 130 located about a pressure relief valve 105 that obtains ultrasonic measurements therefrom. One or more temperature sensors 120, 125 located about the pressure relief valve 105 obtain temperature measurements therefrom. A data acquisition system 135 receives the ultrasonic measurements from the at least one acoustic sensor 130 and the temperature measurements from the one or more temperature sensors 120, 125. An online monitor monitors the measurements received with the data acquisition system 135 for detection of a leak about the pressure relief valve 105. The online monitor 145 detects the presence of the leak as a function of the ultrasonic measurements and temperature measurements. COPYRIGHT: (C)2010,JPO&INPIT |
