ABSTRACT:
A method and apparatus or arrangement, for monitoring the operating characteristics of valves, principally to monitor for failure of a valve. The method including measuring a pressure differential across a valve1and comparing the measured differential with a required differential. If the measured differential is acceptable relative to the required differential, the valve is deemed to be operating acceptably. If the differential is not acceptable relative to the required differential, then further monitoring in the form of flow sensing takes place and is compared relative to required flow characteristics. The method employs a comparison of the pressure differential and the sensed flow characteristics to determine whether the valve is operating acceptably.
