Abstract

A method and a device for the measurement of fluid-mechanically effective parameters of a fluid, with a fluid pump which comprises a delivery element (2) which is mounted in a magnet bearing (10, 10a, 11, 11a), according to the invention, envisages the delivery element (2) of the fluid pump being excited into an oscillation by way of an excitation device (16, 44), wherein the oscillation parameters as well as, as the case may be, the oscillation behaviour is measured, and parameters of the fluid are determined from this.
