ABSTRACT:
In an apparatus for measuring the sizes of fibers, said fibers are diluted into a carrier liquid in a container. The liquid is circulated by means of a pump in a main pipe through a chamber in which a vortex flow exists. A part of the liquid in the chamber is derivated through a small diameter pipe towards a photo-electric analyzing equipment.
