Abstract (en)

[origin: WO2007131918A1] The invention describes a method for processing measurement signals (U<SUB>S</SUB>) from a vortex velocity flow sensor for measuring a flow of a medium through a measuring tube (1), said flow sensor having an accumulator body (3) which is arranged in the measuring tube (1) and a sensor (5) for detecting pressure fluctuations which occur in the region of the accumulator body (3) and for converting these pressure fluctuations into an electrical measurement signal (U<SUB>S</SUB>), with a small demand for computing power and storage space, in which at least part of the measurement signal (U<SUB>S</SUB>) is sampled and digitized, an autocorrelation (AK(T)) of the digitized measurement signal (U<SUB>S</SUB>) is calculated, and the flow is derived using at least one property of the autocorrelation (AK(T)).
