Based on the oil-water flow rate and density obtained with a double-U Coriolis flow meter, and by the help of Support Vector Machine, a direct prediction method of the oil-water respective mass flow rate was developed to avoid the need of study on the complex relation between the slip velocity, water hold up and water fraction.

以双U型Coriolis流量计得到的油水混合物的质量流量和密度为基础，提出了基于支持向量机油水分相质量流量的直接预测方法，避开了直接对滑脱速度、持水率与含水率等之间复杂关系的研究。
