Summary:A filtering apparatus and method of operating a filtering device are disclosed. The apparatus includes a housing having an inlet and an outlet and at least first and second cavities that are coupled to the inlet and outlet, respectively, where an input fluid within the first cavity has an input pressure and an output fluid within the second cavity has an output pressure. The apparatus additionally includes a filter supported within the housing, where at least a portion of the filter extends along an axis within the housing, and the filter at least partly separates the cavities from one another. The apparatus further includes a device capable of determining whether the input pressure exceeds the output pressure by an amount and providing an indication thereof, the device being supported by the housing and extending into the housing along the axis and at least partly into a void within the filter.
