FIELD: metrology.SUBSTANCE: invention relates to metrology, in particular, to methods for measuring transmission parameters of oscillations along a fluid path. Method for determining the parameters of oscillations transmission along a liquid path of elements of pipeline systems is, that the transmission parameters are determined by measuring the vibrational pressure of a sound field generated by an exciter device in a working environment with two or more acoustic loading modes, in three sections for each of the two measuring nozzles installed before and after the element, taking into account the frequency dependences of the attenuation and the speed of sound in a working environment.EFFECT: technical result is the increased accuracy of measurements.1 cl, 1 dwg
