ABSTRACT:
A contamination measurement apparatus for determining a level of particulate contamination in a fluid. The apparatus includes a filter for passing a fluid therethrough. A volume indicator produces movement of a test piston in response to the fluid passing through the filter. The flow decay characteristics of the fluid are determined in response to movement of the test piston. A back flush mechanism returns the fluid back through the filter by use of a back flush piston which reciprocates in a chamber between a first position wherein the back flush piston is engaged with the test piston, and a second position wherein the back flush piston is disengaged from the test piston so that the test piston is free to move in response to the fluid volume.
