Abstract:
A system for determining the volumetric flow rates of the oil/water/gas fractions of multiphase fluid flow in a fluid flow line at each location in a line perpendicular to the flow line parallel to a chord or diameter of said flow line, comprising:a continuous flow watercut monitor placed as a sidestream monitor having an inlet side and an outlet side disposed across an orifice plate in a multiphase fluid flow line, and capable of continuously measuring and providing three separate continuous output signals representative of the oil fraction, the gas fraction and the water fraction of fluid flow in said flow line; means for measuring continuous pressure drop over a constriction of the sample line; and means for moving the physical location of the entrance to said inlet side of said watercut monitor radially along a chord or diameter of a cross sectional plane of said flow line.
