1. A system for determining at least one flow rate of a phase of an N-phase fluid mixture flowing in a conduit, comprising:

  • a speed of sound meter along the conduit for determining the speed of sound in the mixture;

    at least N−

    1 additional sensors along the conduit for providing at least N−

    1 first parameters indicative of the mixture; and

    a computer containing a multiphase flow model which receives the speed of sound and the at least N−

    1 first parameters to compute a flow rate of a phase of the fluid mixture.
