Granted: 1995-10-17
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). Microcom-puter (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 sllut-down are operated. Once the timed intervals and testing are concluded, microprocessor (23) reverts to a powerdown mode to con-serve power. Wake-up timer (29) resets microcomputer (23) at preselected intervals for additional pressure data collection and testing.

Granted: 1998-06-30
Abstract: To measure the level of contents in metallic tanks by means of short electromagnetic waves, it is proposed to mount the complete level measuring assembly, including the horn antenna, outside the tank. The transmitted waves are projected through an opening in the tank wall toward the surface of the medium whose level is to be measured. The opening is closed with a glass or ceramic plate. To distinguish the useful signal within the unwanted echos caused by multiple reflections of the electromagnetic waves at the glass or ceramic plate, a damping layer of a conventional damping material is interposed between the microwave coupling element and the surface of the glass or ceramic plate. To achieve an optimum signal-to-noise ratio, the damping coefficient is fixable and the distance between the level measuring assembly and the surface of the glass or ceramic plate is adjustable in the axial direction of the opening.
