This paper analyzes the problem of multiphase flow metering in the oil and gas industry. The main types of multiphase flow meters, their advantages and disadvantages are considered. A schematic diagram of a multiphase flow meter is proposed, which includes a mixture homogenizer, a Coriolis flow meter, an IR fraction meter and is based on the concept of intelligent measuring systems. An experimental pouring stand has been developed for conducting studies of the absorption of near-infrared radiation in a gas-liquid mixture stream. Studies have been carried out on the absorption of near-infrared radiation in a multiphase flow for a volumetric gas content of 5 and 10% in the range of liquid moisture content from 10 to 90% in increments of 20%. Based on the results of the study, a generalized correlation dependence is obtained. A computational and experimental method is proposed for determining the volumetric ratio of phases in a flow using the parameters of absorption of near-infrared radiation, which can be applied to various ranges of gas content.
