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.

Method and system for measuring the characteristics of a multiphase flow

An electronic system is capable of assuming the role of master module before the proprietary module of the manufacturer of the SCP system, in the absence of a response to the first request from the supervisory system, or when the proposed module detects that the original module is inappropriately carrying out the PCM signal decoding. The system is further capable of monitoring new variables available at the bottomhole, regardless of the limited set of variables provided by the original module of the SCP system.
