<p>The invention relates to a method of determining the rate of flow of a two-phase fluid flowing in a pipe, the method comprising:- constructing (E1) a three-dimensional space (emoy, fmoy, Rdb) in which various two-phase fluid flow speed domains (Dsr, Dsv, Db, Di) are identified, the three dimensions in space being, respectively, the mean spatial position, the mean frequency position and the mean spatial and frequency spread of a flow rate, - calculating (E2), from measurement signals (ms), parameters (emoy p, fmoy p, Rdb p) representative of the two-phase flow rate that is to be determined, and - positioning (E3) the two-phase flow rate that is to be determined in the three-dimensional space (emoy, fmoy, Rdb) on the basis of the calculated parameters.</p> |
