Abstract
The invention relates to a method of measuring the flow parameters of a fluid, and to a device utilizing this method, in which the autocorrelation function of the signal transmitted back by a particle of the fluid in motion is calculated. The mean speed and the variance of the flow are calculated by calculating the derivations of orders 1 and 2 of this autocorrelation function.
