3D approach to designing the excitation coil of an electromagnetic flowmeter

This paper presents 3D hybrid numerical model of electromagnetic flowmeter. Compared to the 2D model used before it is advantageous for the quality of computer simulation, but at the cost of computational burden. Our aim was to compare characteristics of the flowmeter obtained from 2D and 3D simulations to check if faster 2D models can be used for computer aided design of the device. The results of research show that 3D model must be used for optimal design of some parameters of the coil.
