A method for signal processing of measurement signals of a vortex flow transducer for measuring flow of a medium through a measuring tube. The method is characterized by low needs as regards computing power and memory space. The transducer includes a bluff body arranged in the measuring tube and a sensor for registering pressure fluctuations arising at the bluff body and for converting such pressure fluctuations into an electrical measurement signal. In the method, at least a portion of the measurement signal is sampled and digitized, an autocorrelation of the digitized measurement signal is calculated, and the flow is derived on the basis of at least one characteristic of the autocorrelation.
