Abstract: A method for determining a shape of particles in a distribution with reduced measuring and analyzing complexity includes detecting the number of particles, measuring and storing a particle chord length for each particle as a measurement for particle size and measuring at least first and second distributions of the particle size from the particle chord length measured for each particle. The first distribution is based on a first quantity type, the second distribution is based on a second quantity type and the quantity types correspond to different powers of the particle size.

Abstract: A method and an apparatus for determining the particle content of a particle stream using a source of light and two receivers arranged offset from one another in the flow direction of the particle stream. The receivers provide an electrical signal to an evaluation unit as a function of the radiation intensity which they receive, and this signal makes possible a determination of the flow velocity and particle size. Coincident passage of two particles is indicated by a pulse occurring in the signal due to a “roof collapse” in the pulse caused by a weakening of the radiation intensity as the particles pass a receiver.
