Abstract
The results of an experimental investigation into the influence of the cross-sectional bluff body (shedder) shape on the performance of an electrostatic vortex shedding flowmeter are presented. This flowmeter uses the modulated signal of the electrostatic charge deposited on an electrode as a means of registering vortex shedding frequency. In this study, the dimensionless signal to noise ratio was used to assess the performance of each bluff body and various electrode configurations. The results indicate that the meter incorporating a rectangular electrode positioned on the front face of a T-shaped shedder produces the best signal quality and best meter performance.
