FIELD: measurement equipment.
SUBSTANCE: measuring method of volume VD of flow rate of conducting fluids, the conductivity of which is at least jointly determined at least with one parameter p; fluid flows through a vessel having the specified shape, and corresponding volume VD of filling is determined at least with one measured value x that is measured by the measuring device of electrical conductivity, which contains electrodes; the vessel is filled gradually, and then, it is emptied through an outlet connection pipe; as a result, height h of filling constantly varies. At least one reference table is composed, which contains measured calibration values xR and filling volumes VD referring to them by means of calibration measurements, thus using several fluid samples that have different values p and different heights h of filling in the vessel. Values x are measured at time interval, and corresponding filling volumes VD are determined by comparison of the corresponding measured values x with values xR of the table, and flow rate volume vD is determined based on filling volumes VD during the specified period of time. Measuring device (10) for determination of flow rate volume vD of conducting fluids through vessel (5) includes at least two measuring electrodes (22, 24).
EFFECT: creation of the method and the measuring device, which allow easier and more accurate measurement of volumetric flow rate of fluid through the vessel.
