An automated technique to measure the settling velocity of particle su
spensions has been developed. The technique relies on the measurement
of conductance as solids settle through a conductivity cell. The cell
consists of two electrodes mounted flush with the wall of a cylinder a
nd separated by a set distance. The technique is illustrated by determ
ining settling velocities for single and mixed sizes of silica, and as
means of detecting particle agglomeration. (C) 1997 Elsevier Science
