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