A fuel monitor assembly for use in testing the contamination level of a fuel sample is disclosed, including a housing having a fuel inlet and a fuel outlet, and a fuel filter capsule disposed within the housing. The filter capsule includes an inlet half and an outlet half, wherein the halves interfit to retain a membrane filter therebetween. The inlet half of the filter capsule is integrally formed with an inlet dispersion structure that radially disperses an incoming stream of fuel so as to equalize the pressure across the face of the membrane filter, thereby resulting in even distribution of contaminant particulates deposited on the membrane filter. The outlet half of the filter capsule is integrally formed with a recessed, radially symmetric grid configuration that channels fuel passing through the membrane filter to the fuel outlet, and also encourages equal pressure distribution across the face of the membrane filter.

A filter capsule assembly through which a fluid sample is passed in order to filter off particulates suspended therein, wherein the particulates are subsequently analyzed to determine the particulate contamination level of the fluid sample, comprising: an inlet half including an inlet bottom wall, a fluid inlet opening extending through said inlet bottom wall, and an inlet side wall extending upwardly from said inlet bottom wall, said fluid inlet opening extending along a longitudinal axis substantially normal to said inlet bottom wall and having along the axial length thereof a minimum transverse cross-sectional area; an outlet half including an outlet bottom wall, a fluid outlet opening extending through said outlet bottom wall, and a generally cylindrical outlet side wall extending upwardly from said outlet bottom wall, said inlet half and said outlet half being adapted to engage one another to define a filter chamber bounded by said inlet and outlet bottom walls and said inlet and outlet side walls; a filter element retained intermediate said inlet bottom wall and said outlet bottom wall within said filter chamber when said inlet half and said outlet half are engaged; and means for distributing said particulates on said element in a layer of substatially uniform thickness, including fluid dispersion means associated with said inlet half for radially dispersing a stream of fluid that would enter said filter chamber through said fluid inlet along said longitudinal axis, said fluid dispersion means comprising a fluid-contacting plate member and support means extending between said inlet bottom wall and the peripheral edge of said plate member for supporting said plate member in spaced relationship with said inlet bottom wall, said plate member having a fluid-contacting surface facing said inlet bottom wall in registry with said fluid inlet opening along said longitudinal axis, the area of said fluid-contacting surface being no greater than said minimum transverse cross-sectional area of said fluid inlet opening.
