PCT No. PCT/SE85/00073 Sec. 371 Date Oct. 15, 1985 Sec. 102(e) Date Oct. 15, 1985 PCT Filed Feb. 13, 1985 PCT Pub. No. WO85/03774 PCT Pub. Date Aug. 29, 1985.A measuring device by which it is possible to measure individually the content of each type of substance in a suspension with at least two types of suspended substances provided the density of the substance in each type is approximately equal and the densities of the substances included in the individual types are known. The measuring device comprises a density meter (10) known per se arranged to measure the density of the suspension and the density of the liquid in which the substances are suspended in order to determine the difference in density. Moreover, the measuring device comprises an apparatus (12) known per se and intended for measurement of particle concentration, which is arranged to measure the ratio of the volume of the suspended substances to the volume of the liquid. Finally, the measuring device also comprises a calculating unit (26) electrically connected to the density meter and the apparatus for measurement of particle concentration. The calculating unit is arranged to combine signals received from the density meter (10) and said apparatus (12) in order to calculate the concentrations of each of the substance types on the basis thereof.
