1. A method for measuring characteristics of a multiphase flow from structural vibration signals, the method comprising:
obtaining, by means of acceleration sensors fixed externally to a pipeline, signals based on the pipeline internal flow vibration;
processing, by means of a processing device, the obtained signals;
determining a dispersion curve fitting coefficient to determine the void fraction of the mixture; and
controlling a flowrate of a pump, by the processing device, based at least in part on the determined void fraction of the mixture.
