it is desc.pi.bed a method of measurement of the volume V D of the flow-rate of electrically conductive liquids the conductivity of which is at least codetermined by at least one parameter p, wherein the liquid flows through a vessel having a predetermined shape, and wherein the respective filling volume V o is determined by at least one measured value x, which is measured by an electrical conductivity measuring device comprising electrodes, wherein the vessel is filled in succession and then is emptied through its outlet, through which the filling heights h are constantly changing. At least one reference table comprising calibration measured values X R and filling volumes V o belonging to them is constructed by means of calibration measurements using several liquid samples, which have different p-values and different filling heights h in the vessel. The measured values x are measured in time intervals and the respective filling volumes V o are determined by comparison of the respective measured values x with values X R of the table, and the volume V D of the rate of flow is determined from the filling volumes V o over a time period. The measuring device (10) for the determination of the volume V D of flow rate of electrically conductive liquids through a vessel (5) comprises at least two measuring electrodes (22, 24).
