Abstract

The Rapid Sediment Analyzer provides information on the size distribution of a sample of finely divided particulate matter (e.g. sand) by monitoring the weight and the rate with which the particles fall through a column of liquid (e.g. water). A digital computer connected to the Analyzer reports the particle size distribution directly.
