Abstract
Method and apparatus for obtaining the average aspect ratio of non-spherical particles in suspension. The particles are caused to orient generally in one direction and the conductivity of the particles are measured in such direction while simultaneously measuring the conductivity of the particles in a traverse direction. The difference between the two conductivity measurements is indicative of the average aspect ratio of the particles in suspension.
