Modeling and Simulation of Capacitance Vortex Flow Sensor

The structural characteristics of one kind of the capacitor vortex flowmeter was introduced for raising up its survey performance. According to elaborately expounding the vortex survey theory, the mathematical relation between the variations of vortex force and capacitor was studied. The mathematical model of vortex flow survey was established and simulated and the simulated results were carefully analyzed. The author comes to conclusion that the measures of decreasing the natural frequency of testing component, increasing the width of capacitor and electrodes are of value to raising up the sensibility of the capacitor vortex flowmeter. Carrying out mathematical modeling and simulation to the capacitance vortex flow sensor can bring further comprehension to the system. And the method is effective to the design and consummation of the capacitance vortex flowmeter.
