“…Although the diverter reduces the sensitivity of TFM to the concentration profile to a certain extent, due to the large difference in density and viscosity between gas and liquid, there will still be interphase slippage and local uneven distribution of concentration and velocity. Hence, it is necessary to combine other sensors to explore the TFM measurement model of the two-phase flows after passing through the diverter [17,18].…”

Although turbine flow meters (TFM) have made good progress in measuring flow with accurate response characteristics in single-phase flow, TFM combined with other sensors to measure two-phase flow is still a difficult and hot issue. Due to the leakage after the collection, the flow state change and slippage between the gas and liquid phases in the pipeline after the diversion are complicated, and all these factors have a significant impact on the TFM modelling. Therefore, the meter factor models of the TFM with diverter in twophase flows have not been thoroughly solved. Thus, this study mainly investigates the performance of TFM in gas-liquid two-phase flows combined with the rotating electric field conductance sensor (REFCS). Among them, the gas holdup is implemented through the REFCS. We examine three two-phase flows TFM models including mass model, momentum model and torque model, and analyse slip ratio, an essential parameter in the meter factor models. Subsequently, based on model tests, the evaluation finds that the Chisholm slip ratio model combined with the torque model achieved the best accuracy. Consequently, the average absolute deviation (AAD) and average absolute percentage deviation (AAPD) of total flow rate are 1.23 m 3 /d and 7.69%.
