A new flow velocity measurement method based on the ring electrostatic sensor

Abstract Gas-solid two phase flow widely lies in industry process, while its parameters measurement (flow velocity, the mass flowrate, particle sizes, et al.) is very difficult. This paper mainly studies solid velocity questions of gas-solid with ring electrostatic sensor. During study, a new mathematical model sensor established, and by simulating obtained spatial filter characteristics are obtained. By analysis sensor, method this paper. At last, some experiments accomplished laboratory line sand. The measuring effective these experiments. calibrated cross-correlation velocity. When sand less than 7m/s, repeatability error measured ± 10%.
