More Information
Summary:A method for measuring liquid flow, comprising the steps of delivering the liquid into a measuring cell having a measuring slot with at least one isolated electrode and at least two non-isolated electrodes, inducing fluctuations in the liquid flowing in the measuring slot, measuring electrical capacitance and electrical phase shifts correlated with the fluctuations, as well as a conductivity of the liquid, and obtaining flow parameters of the liquid from the electrical parameters. An apparatus for measuring the properties of a flowing liquid, comprising at least one measuring cell having at least one measuring slot, means for inducing flow fluctuations in the flowing liquid, and measuring means used to obtain liquid properties from the flow fluctuations.
