  • Apparatus and method for measuring liquid and gas flow rates in a stratified multi-phase flow
    Patent number: 8229686
    Abstract: A method and apparatus for measuring a flow rate of a component of a stratified two-phase fluid flow within a substantially horizontally extending pipe is provided. The method includes the steps of: a) determining a first fluid velocity value and a second fluid velocity value within the pipe section; b) determining a density of the fluid flow within the pipe section, and creating a measured fluid density value; c) determining a degree of fluid phase stratification of the fluid flow using at least one of the top and bottom fluid flow velocity values, and the measured fluid density value; and d) determining a flow rate value for at least one of a liquid component of the fluid flow and a gas component of the fluid flow within the pipe section.
