ABSTRACT:
A method and apparatus for measuring a parameter of a wet gas flow is provided, wherein the apparatus includes a differential pressure based flow meter configured to determine a first volumetric flow rate of the wet gas flow. Additionally, the apparatus includes a sonar based flow meter configured to determine a second volumetric flow rate of the wet gas flow. Furthermore, the apparatus includes a processing device communicated with at least one of the differential pressure base flow meter and the sonar based flow meter, wherein the processing device is configured to determine the parameter (e.g., wetness, volumetric gas flow rate, and volumetric liquid flow rate) of the wet gas flow using the first and second volumetric flow rates.
