Abstract
It is described a method of measurement of the volume Vof 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 Vis 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 xand filling volumes Vbelonging 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 Vare determined by comparison of the respective measured values x with values xof the table, and the volume Vof the rate of flow is determined from the filling volumes Vover a time period. The measuring device for the determination of the volume Vof flow rate of electrically conductive liquids through a vessel comprises at least two measuring electrodes.
