A filter system of the type having a pressure vessel having an annular filter media therein with a filter wiper piston moved by an air or hydraulic piston actuator. An electrically operated drain valve purges wiped contaminants from the filter media. Pressure sensors provide a signal to a controller of vessel inlet and outlet pressure. Position detectors provide signals to the controller of the drain valve position and filter actuation position. The controller has a computer which computes from the sensor inputs parameters representative, in real time, of entry fluid condition, relative amount of filter contamination, relative amount of filter wear, and relative amount of contaminant removal, and provides signals of the representation to indicators providing visual display thereof.
