1. A method for measuring the phase fraction of the constituents in a fluid mixture in a conduit, comprising:

  • displacing at least three sensors along the length of the conduit;

    measuring a naturally occurring pressure variation in the fluid at each of the sensors to produce a pressure variation signal; and

    computing the phase fractions of the constituents in the fluid mixture using the pressure variation signals.
