Abstract

The spatial filter measurement principle of flow velocity is obtained by point charge mathematical model of the electrostatic sensor, and signal cut-off frequency is acquired with "3dB" principle during real-time measuring flow velocity. Experiments prove that the spatial filter measurement velocity principle of inducement probe is feasible, and experiments separately examine the flow velocity with this measurement priciple in range of 2-7m/s.
