An alternative analysis method for evaluating electromagnetic flowmeter performance

The weight function method (WFM) is compared with the magnetohydrodynamics (MHDs) coupled solver approach for single‐point and multipoint magnetic flowmeters downstream of a distorted flow created by a long radius 90‐degree elbow. A review of the literature appears to indicate that researchers who are interested in magnetic flowmeter accuracy and performance either have been unaware of or not capable of analyzing magnetic flowmeters using the WFM. The study examines whether any differences are apparent between modeling the single‐point electrodes and omitting the electrodes from the model. The results of the study indicate differences less than 0.50% between the WFM and the MHD approach. The results also demonstrate that for single‐point flowmeters, modeling the electrodes is not necessary. This research eliminates the barrier of deriving a weight function to model magnetic flowmeters.
