Numerical Simulation and Verification of Weight Function of Electromagnetic Flow Meter with Non-insulation Pipe Wall
نویسنده
چکیده
Weight function distributions for an electromagnetic flow meter with a non-insulating pipe are numerically simulated and verified. The weight function distribution is very important for solution of flow velocity of distribution. In this paper, a finite element method (FEM) is used for solving the weight function distribution for this novel electromagnetic flow meter. First of all, a numerical simulation model of an electromagnetic flow meter with non-insulating pipe wall is built by the Comsol Multiphysics software. The Boundary condition of weight function is researched. Secondly, weight values for different kinds of ‘noninsulating pipe electromagnetic flow meters’ are analyzed. These non-insulating pipe electromagnetic flow meters have pipes with different conductivities and thicknesses. At lastly, inducted electromotive force between the pair of electrodes of the novel EMFM is researched in this paper. The result of distribution of virtual current is the same as weight value distribution has been proved under situation of uniform magnetic field. This method can be used in analysis different weight functions in other fields like prolusion of surface pipes and electrode poles of electromagnetic flow meter. It is very meaningful in medical and industrial field. Copyright © 2014 IFSA Publishing, S. L.
