Abstract
A centrifugal filter element is inserted into a pipeline to provide a dry oil stream for analysis. A moisture sensing probe is inserted along the central axis of the centrifugal filter to sense the properties of the dry oil stream therein. A second probe is inserted into the pipeline to sense the properties of the undried oil. Comparison of the output of the two probes reveals the water content of the oil in the pipeline.
