ABSTRACT:
An instrumental measuring method for determining the size-distribution of grained material is described in which the material is evenly distributed in a fluid then the fluid is let in rest state when the materials gets sedimenting, and during sedimentation the hydrostatic pressure is continuously measured in at least two height regions of the fluid preferably by appropriate pressure sensitive transistors and the difference of the measured hydrostatic pressures is characteristic of the size-distribution of the grained material on the basis of the well-known Stokes' relation.
