Valve monitoring system and method
First Claim
1. A valve monitoring system including an alert generation system and a memory, the memory encoding baseline acoustic emission data on the valve for a predetermined period of operation, the alert generation system being arranged to receive acoustic emission data for the valve, compare the received acoustic emission data for the valve with the baseline acoustic emission data encoded in the memory and identify valve anomalies in dependence on differences in the received acoustic emission data and the baseline acoustic emission data.

Abstract
A valve monitoring system includes an alert generation system and a memory. The memory encodes baseline acoustic emission data on the valve for a predetermined period of operation. The alert generation system is arranged to receive acoustic emission data for the valve, compare the received acoustic emission data for the valve with the baseline acoustic emission data encoded in the memory and identify valve anomalies in dependence on differences in the received acoustic emission data and the baseline acoustic emission data.

15. In a valve monitoring system, a method for monitoring valves comprises:
-
obtaining a baseline acoustic emission signal for a valve for a predetermined period of operation;
obtaining a further acoustic emission signal for the valve for the predetermined period of operation;
comparing the baseline acoustic emission signal with the further acoustic emission signal;
identifying valve anomalies in dependence on differences between the baseline acoustic emission signal and the further acoustic emission signal. - View Dependent Claims (16, 17, 18, 19, 20)
