ABSTRACT:
The density r of a fluid, e.g. dispersion or suspension, is measured in a plurality of steps and by calculating the same according to the formula r=c.times.dG/dV, wherein c is a constant value and dG/dV is the differential of the weight measuring value dG to the volume measuring value dV. In this way some measuring inaccuracies of the measuring instruments can be avoided.
