Filter life measurement
First Claim
1. A method of measuring remaining useful life of a filter comprising:
- flowing a particulate-laden fluid through a filter;
measuring a parameter of the flow during the flowing; and
producing, from the measurements of the parameter, measurements that indicate the remaining useful life of the filter in a way that varies generally linearly during the time that fluid is flowing through the filter, including storing in a store a previously measured correlation between the parameter and remaining useful life for a previous filter corresponding to the filter on flowing a particulate-laden fluid substantially corresponding to the particulate-laden fluid therethrough, the store receiving the measurements of the parameter and outputting measurements of the remaining useful life corresponding to the received measurements of the parameter and derived from the previously measured correlation for the previous filter.

Abstract
A method of measuring the remaining useful life of a filter may comprise flowing a particulate-laden fluid through a filter and measuring a parameter of the flow during the flowing. From the measurements of the parameter, measurements of the remaining useful life of the filter that vary linearly during the time in which the fluid is flowing through the filter may be produced. The method may include, storing in a store a previously measured correlation between the parameter and the remaining life for a trial filter corresponding to the filter on flowing the particulate-laden fluid therethrough. The store may receive the measurements of the parameter and output measurements of the remaining useful life corresponding to the received measurements of the parameter and derived from the previously measured correlation.
