ABSTRACT:
A multi-phase fluid flow measuring system for measuring the volumetric fractions of gas, water and oil including a centrifugal separator for conducting primary separation of gas from the liquid phase, a conduit section forming a closed chamber and a piston displaceable into the chamber to measure the increase in pressure of a liquid sample trapped in the chamber in relation to movement of the piston for determining the residual gas content of the liquid phase, a liquid phase flow meter and apparatus for measuring the microwave energy transmissivity through a sample of the liquid phase to determine the volumetric fraction of water and oil in the liquid phase. One embodiment of the system uses two apparatuses for measuring the microwave transmissivity at different pressures of the liquid phase to compare the transmissivity readings as a way of determining the residual gas content in the liquid phase. A method for measuring the residual gas content takes into consideration an increase in pressure in the sample of liquid being measured including elastic stretch of the measuring vessel as a result of the pressure increase, and compressibility of the liquid phase.
