The paper presents results of the first stage of experimental verification of the theoretical concept published in the two first preceding communications concerning the flow of liquid in a continuous nonideal mixer and, namely, the smoothing effect of such a mixer on a passing stationary random concentration signal. In a sufficiently wide range of experimental conditions it has been proven that stochastic fluctuations of the distribution of the residence time of liquid in the mixer do not contribute significantly to the variance of the outlet random signal of the mixer. Further, a good agreement has been proven between the experimental data and the model relationship for the smoothing effect of the mixer based on the application of the gamma distribution of the residence time.
