摘要

Arrangement for measurement of particle content in a suspension with which it is possible to individually investigate the content in each type of substance in a suspension with at least two types of suspended matter and in which the density of each type of substance is essentially the same and the densities of the substances included in the individual types are known. The measurement arrangement includes a density meter 10, which is of a known type and is arranged to measure the density of the suspension and the density of the liquid in which the substance is suspended to determine the density difference. The measurement arrangement also includes a device 12 that is of the known type and which is intended to measure particle concentration, and which is arranged to measure the ratio between the volume of suspended substance and the volume of liquid. Finally, the measurement arrangement also includes a computer device 26 that is electrically connected to the density meter and to the meter for measuring particle concentration. The computing unit is arranged to combine the signals coming form the density meter 10 and from said device 12 to determine the concentration of each substance type based on this.
