Abstract Aiming at the problems of traditional near-infrared point-to-point probe sensor measurement blindness and low data accuracy, a gas-liquid two-phase flow phase content measurement device based on near-infrared surface source sensor was proposed and designed. The device effectively reduced the refraction and reflection of near-infrared light and improved the accuracy of the measurement. The flow state of the fluid in the pipeline was simulated by CFD fluid simulation software, and the structure of the device was simulated and optimized. Based on the single-phase flow experiment, the dynamic experiment of gas-liquid two-phase flow was carried out, and the relationship between the four-way near-infrared signal and the phase-containing ratio was obtained. The phase-containment rate measurement model was established, and the phase-inclusive rate measurement was obtained by data import correction model analysis. The relative error is within ±3.5%.
