The paper presents principles of fractal analysis of measurement signals. The application of such indicators as autocorrelation function. Hurst exponent, the largest Lapunow exponent, correlation dimension. Kołmogorow entropy for the measuring signal analysis are discussed. The fractal analysis of experimental data was used to analyse the results of registration of local changes of gas void fraction in the flow of water-air mixture crosswise to the tube bundle in the shell-side space. The occurrence of low dimensional attractors of correlation dimensions close to D₂=1.1 and D₂=3.9 was found.
