Solving Weight Function for the Partially Filled Pipe Electromagnetic Flowmeter by Means of Finite Element Numerical Analysis

Abstract:

The weight function method that uses a known weight function has been a general tool for the signal analysis of the electromagnetic flowmeter(EMF). However, it is difficult to solve the voltage equation directly by analytical method in order to get weight function for the partially filled pipe electromagnetic flowmeter(EMF-PF). The finite element numerical analysis method is tried to solve the weight function for the EMF-PF in this paper. The results show that weight function for EMF-PF relates to fill height of liquid in partially filled pipes, and there is a nonlinear function relationship between weight function for EMF-PF and fullness degree of liquid in the pipe.
