Abstract
An optical flow cell includes a housing having an inlet coupled to an outlet through which a sample fluid material flows. A viewing assembly, carried by the housing, includes a pair of opposed plates having a gap therebetween which is in fluid communication between the inlet and the outlet. One of the plates extends outwardly from the housing for use as a reference point in a fluid sampling device. The flow cell is positioned between a light source and an imaging system to detect particle shape and size as the fluid passes through the viewing assembly.
