Abstract: The present disclosure relates to a method for operating a magnetoinductive flowmeter in which, during a constant phase having a constant magnetic field, a plurality of raw measured values of the raw measurement voltage are determined, the raw measurement voltage including a flow-dependent component, an interference component and a noise component, wherein each raw measured value assigned a flow measured value and an interference voltage value, wherein a raw measured value from a preceding first constant phase and a raw measured value from a second constant phase following the first constant phase are used to calculate a second flow measured value and a second interference voltage value of the interference component, wherein first flow measured values from the first constant phase and/or second constant phase are corrected using the knowledge of the second flow measured value and the calculated second interference voltage value.
