Method for operating a vortex flowmeter device for measuring the flow of a fluid that flows through a measuring tube in which a baffle is arranged for producing eddies in the fluid. A signal-processing device processes signals of first and sensors produced by pressure fluctuations. A first signal is obtained by multiplication of the signal of the first sensor with a correction factor, and the second signal is obtained by multiplication of the signal of the second sensor with another correction factor such that a wanted signal is obtained from the deviation between the first signal and second signals, and a sum signal is formed from the sum of the first and second signals. A correlation between the wanted signal and the sum signal is determined and the correlation is minimized by variation of the correction factors, whereby same-phase interfering signals superimposed on anti-phase sensor signals are at least minimized.
