To improve the wet gas metering accuracy by using a vortex flowmeter, aiming at the problems of low prediction accuracy and narrow application scope of the traditional meter overreading correlations, a meter overreading model based on flow parameters of the entrained droplets (entrainment fraction and droplet size) was proposed. To conduct experimental studies on different entrained droplet conditions, the annular mist flow loop based on atomizing mixing was developed, and the optical imaging system was built to measure the droplet diameter and distribution. The dimensionless scaling parameters were discovered by combining the annular mist flow pattern with the vortex meter overreading mechanism and taking into account the droplet-liquid film mass transfer and the droplet-vortex coupling mechanism. The meter overreading model was developed with liquid mass loading, Weber number and Stokes number, taking the effects of the entrained droplet parameters and the carried gas parameters (density and velocity) into consideration, thus, its application scope is expanded. Finally, the performance of other overreading correlations was evaluated and analyzed by the differences of the entrained droplet parameters in their experimental conditions and the model assumptions. The results indicate that the proposed model provides a uniform prediction for the meter overreading, the relative deviations are within ±1.0% error band, both the predicted accuracy and the model extensibility are greatly improved compared with other overreading correlations.
