Abstract
The invention is a kind of measuring device for the gas-liquid flow rate of multiphase fluids. The device includes a means for generating static slug flow and a means for measuring the flow rate by cross-correlation. These means are mounted on the pipe through which the multiphase fluids such as gas liquid flow. The device includes a multiphase fluid regulating means and a multiphase fluid fraction measuring means. These means are mounted on the pipe through which the multiphase fluids such as gas liquid flow by cross-correlation orderly. Said multiphase fluid regulating means lies in the downstream of said measuring means or said multiphase fluid fractions measuring means lies in the upstream of said generating means for static slug flow. The device also includes a means for data acquisition and data procession. The means is used for acquiring and processing the measuring data. The flow rate of each fraction is calculated from the multiphase fluid fractions measuring means and the measuring means for the flow rate by cross-correlation.
