This article presents use of the classical spectral analysis to identify a type of flow in investigation of gas transportation by liquid with a measurement of gamma radiation absorption. During numerous experiments it was found that a magnitude of the cross-spectral density distribution of recording signals reveals type of air-water mixture flow in a horizontal pipeline. As an example, some results of laboratory measurements equipped in 241Am radiation source and scintillation probes with of NaI(Tl) crystals are presented. Moreover attached figures facilitate interpretation of observed results and in details illustrating the proposed method.
