ABSTRACT:
A measuring cell (22) in a fiber sample analysis system (10) contains housing member (76) which removably supports a transparent flow tube (82) and an optical device (26) which projects a beam (124) across the tube for detecting and measuring individual fibers in a dilute sample fluid which flows through the tube at a constant velocity. The tube includes a gradually narrowing transition portion (86) leading to a measurement portion (88) situated at the optical device and having a flow diameter in the range of about 1.0 to 3.0 mm.
