| Abstract: | Based on the principle of flow-induced cavity resonance,a type of flow rate measuring device with simple structure and no moving parts is proposed.This measuring device has the advantages of low pressure loss,fast transient response.Furthermore,an energy harvesting method based on the effects of flow-induced cavity resonance and piezoelectric conversion is proposed to supply electricity for the signal measurement,data process,and data transmission. |
