Abstract: A method and apparatus for determining a fluid level within an enclosed housing. The present invention provides an enclosed housing having a dynamic fluid level contained therein. The apparatus includes an electromagnetic radiation source for directing electromagnetic radiation rays toward the interior of the enclosed housing and an electromagnetic radiation detector for receiving and measuring reflected electromagnetic radiation rays. The electromagnetic radiation detector provides a detector output signal to a controller. The controller interprets the detector output signal to determine whether the fluid level has statically reached a desired level and then generates a controller output signal for indicating that the fluid level has statically reached the desired level. The method includes the steps of generating a logic signal in response to the measured electromagnetic radiation and analyzing the logic signals over a period of time to determine whether a predetermined fluid level has been reached.

Abstract: A method and apparatus for filtering pressurized fluids, wherein a fluid level provides a visual indicator as to the general condition of the filter element. The present invention provides a vertical housing having a fluid inlet for communicating the fluid into said housing and a fluid outlet for communicating the fluid downstream of the housing. A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. The volume of air within the vertical housing is specifically determined in order to maintain a level of fluid which will indicate the general condition of the filter element.
