This paper is concerned with a newly developed measurement technique of particle flow-rate in gas-solids pipe flow based on the static electrification of particles. The method is found to be feasible to detect the flow-rate as small as 0.5g/s for large alumina particles of 0.3mm in mass median diameter. Here we investigated the effect of sensor vibration on the detection sensitivity to obtain the fundamental data for practical applications of the sensor in various particulate processes such as sand blasting. The jet tests with alumina particles were carried out using a vibration exciter at various frequencies and amplitudes. According to the experiments, it was found that the detection sensitivity increases with the vibration and the sensor can be applied even when the acceleration of vibration is as large as 30G. It was also found that the resonance of the sensor vibration has no significant influence on the measurement of particle flow-rate.
