Patent ID: 7707897

Claim:
A method of estimating multi-phase fluid flow through a two stage flow meter comprising: a. measuring fluid conditions within the flow meter and the flow meter exit; b. calculating an initial estimated value of total fluid flow (q m, old ) through the flow meter c. calculating a differential pressure measurement correction factor based on the initial estimated value of total fluid flow; d. calculating a new estimated value of total fluid flow (q m, new ) through the flow meter using the differential pressure measurement correction factor; e. calculating a new correction factor based on q m, new and setting q m, old equal to q m, new , f. comparing the values of q m, old with q m, new and repeating steps (c) through (e) if q m, old and q m, new are not equal; and g. calculating a corrected value of total fluid flow when q m, old and q m, new are equal.
