    Abstract: The demand for multiphase flow measurement is widespread in petrochemical and other fields. Due to its small size, easy maintenance, and no moving parts, electromagnetic flowmeters are widely used in single fluid measurement. With the increasing application of traditional electromagnetic flowmeters in petrochemical and other fields, the problems of traditional electromagnetic flowmeters in multiphase flow measurement applications have been discovered. How to optimize the structure of the electromagnetic flowmeter and how to improve the measurement accuracy has become a new research focus. On the basis of a large number of literature studies, this research is based on the finite element method, and systematically studies the influence of multiphase flow on the weight function of electromagnetic flowmeters. Firstly, modeling the existence of non-conductive objects in the electromagnetic flowmeter. Secondly, analyze the weight function characteristics of the non-conductive objects on the electromagnetic flowmeter from two angles of different radii and different positions. The conclusions of this study can provide a certain reference basis for the electromagnetic flowmeter in the measurement of multiphase flow.

    Abstract: Standard flow facility is a platform for performance test of flowmeters. Flow diverter is an essential component of liquid flow facility based on flying start-and-stop method, and is also a key equipment deciding the uncertainty of flow facility. In order to improve the accuracy of large flow facilities, the effects of acceleration performance and liquid shock force on the uncertainty of the flow diverter with large flow rate is analyzed. The actuation structure using servo motor and reducer to drive the flow diverter is put forward. The effect of step motor and servo motor on the uncertainty of the flow diverter is verified by real-flow test. The results of experiment indicate that servo motor driven flow diverter has faster transfer acceleration and more stable transfer process. The test results of transition time difference method show that the uncertainty of servo motor driven flow diverter is less than 0.003%.
