W artykule omówiono wybrane metody analizy sygnałów stosowane w radioizotopowych absorpcyjnych pomiarach parametrów przepływów dwufazowych: metodę korelacji wzajemnej i metodę fazy wzajemnej gęstości widmowej mocy. Na wybranych przykładach pokazano wykorzystanie obydwu metod do pomiaru prędkości przepływu fazy gazowej w mieszaninie woda-powietrze transportowanej rurociągiem poziomym. Wyznaczono i porównano niepewności wyników pomiarów prędkości uzyskane przy zastosowaniu prezentowanych metod.The paper presents gamma absorption methods applied to two-phase flow evaluation by advanced statistical analysis of the recorded stochastic signals. Two selected methods based on the cross-correlation function and the phase of the cross-spectral densit...
