Abstract
Abstract A method and apparatus are described for determining the weight of a moisture-free, compressible material in a given volume of fluid suspension. The given volume of the suspension is confined and the material in the confined suspension is compressed with a movable porous surface at a predetermined pressure to form a mat of the material. The thickness of the mat thus formed is measured and the weight of the material is determined therefrom from a known relationship. The apparatus may be flushed out by movement of a lower non-porous piston which retracts to open an outlet from the chamber.

A method for determining the weight of a moisture-free, compressible material in a given volume of fluid suspension, comprising, confining the volume of the fluid suspension, compressing the material in the confined fluid suspension with a porous surface at a predetermined pressure to form a mat of the material, measuring the thickness of the mat thus formed after a predetermined first time interval after compressing the material, said thickness being measured over a predetermined second-time interval, and determining the weight of the material from a known relationship thereof to the mat thickness.
