油水两相流相含量和流量的同时测量在过程工业中具有重要意义。提出了一种用于测量这两个参数的紧凑型流量计--电导环耦合圆锥流量计（CRCC），该流量计将用于测量流量的长腰圆锥流量计（LWC）和用于测量相分数的位于LWC环形通道处的一对电导环相结合。CRCC利用LWC和电导环的空间特性来实现对流量和相分数的更可靠的估计。LWC（直径比β和腰部长度L）和电导环（电极之间的间隔L-e）的尺寸考虑总压降和电感测场的灵敏度而联合优化。制作了一个β = 0.65，L = 50 mm，L-e = 15 mm的CRCC，用于静态标定和动态油水两相流测量试验。动态实验结果表明，建议CRCC是能够提供的相分数和个人流量的相关平均相对误差低于5%，经过简单的校准推断。
Simultaneous measurement on the phase fraction and flow rate of oil-water two-phase flow is of significance in process industries. A compact flow meter conductance ring coupled cone meter (CRCC) is presented to measure these two parameters by combining a long-waist cone meter (LWC) for flow rate measurement and a pair of conductance rings at the annular channel of the LWC for phase fraction measurement. The CRCC utilizes the spatial characteristics of LWC and conductance rings to achieve more reliable estimations on flow rate and phase fraction. The sizes of the LWC (diameter ratio beta and waist length L) and conductance rings (separation L-e between electrodes) are jointly optimized considering the overall pressure drop and sensitivity of electrical sensing field. A CRCC of beta = 0.65, L = 50 mm, and L-e = 15 mm is fabricated for static calibration and dynamic oil-water two-phase flow measurement tests. The dynamic experimental results demonstrate that the proposed CRCC is capable of delivering inferences on phase fraction and individual flow rate with an associated average relative error below 5% after easy calibration.
