ABSTRACT:
A device (10) for detecting irregular operation in a pressurized fluid vessel, such as leaks in a pipeline (20), includes a transducer (21) for measuring pipeline (20) instantaneous pressure, a microcomputer (23) and a wake-up timer (29). Microcomputer (23) performs several different tests upon the collected pressure data to reliably ascertain if a leak or break in pipeline (20) has occurred. The first test involves a comparison of rates of change of pressure at successive preselected timed intervals, referred to as timed interval comparisons. If any test is failed, an alarm (30) and/or actuator (31) for valve or system shut-down are operated. Once the timed intervals and testing are concluded, microprocessor (23) reverts to a powerdown mode to conserve power. Wake-up timer (29) resets microcomputer (23) at preselected intervals for additional pressure data collection and testing.
