Abstract

The paper describes the dynamic characteristics of a flowmeter. When a usual rectangular wave excitation is adopted, the effect of an electric double layer at a boundary of fluid and metallic pipe wall cannot be neglected. Since is is difficult to analyze the distributed physics of the layer, a lumped equivalent circuit model which consists of parallel capacitance and resistance with series resistance is constructed and overall dynamics of the flowmeter is studied through computer simulations. Both results of the simulation and the experiment of the new circuit configuration show good performance and the suppression of the effects of the capacitance and the conductivity.
