Abstract
The present invention relates to a method and system for measuring characteristics of a multiphase flow from structural vibration signals. In this sense, the objectives of the invention are achieved by means of a method for measuring characteristics of a multiphase flow from structural vibration signals which comprises: obtaining, by means of acceleration sensors (V, V, T) externally fixed to a pipeline, signals based on pipeline internal flow vibration; processing, by means of a processing device, the obtained signals; and determining a dispersion curve fitting coefficient to determine the void fraction of the mixture.
