1. A method, comprising:
obtaining, by a computer processor and from a plurality of sensors, acquired sensor data regarding one or more multiphase flows in a multiphase flow meter that are sampled at a predetermined sampling frequency, wherein the acquired sensor data describes a plurality of transient signals that correspond to a plurality of gas droplets;
generating, by the computer processor and based on the acquired sensor data, a flow model for the multiphase flow meter;
updating, by the computer processor, the flow model to produce a first updated flow model using simulated flow data; and
updating, by the computer processor, the first updated flow model to produce a second updated flow model using simulated sensor data,
wherein the second updated flow model is used to determine one or more flow rates within a multiphase flow, and
wherein the predetermined sampling frequency corresponds to a frequency value greater than a ratio of a predetermined flow velocity to a size of a sensing electrode for an electromagnetic measurement of the one or more multiphase flows.
