Abstract

Abstract: The article discusses modeling procedures to capture the physical and chemical processes present in operational measurement with a high-precision inductive flowmeter. In this context, a theoretical model and a numerical solution are proposed. Exploiting the combined finite element method (FEM) and the finite volume method (FVM), we prepared numerical models of multiple variants of the flowmeter and computed the output voltage on the device's electrodes. The model joins together the magnetic, electric, and current fields; a flow field; and a physical-chemical nonlinear ion model. The results were obtained by means of the FEM/FVM in ANSYS software and verified via experimental testing. Highlights: We discuss and compare both the results obtained from the design of the classical combined model of the electromagnetic method and experimental flow measurement with its limits of the measured flow velocity. As a new design and testing of liquid flow measurement from the range of velocities v = 0.01 - 1 mm/s. Laboratory experiments and verification of the proposed models were performed.
