| Abstract: | The operation principle,structure design and key technique of a flow velocity sensor are presented.Based on the Pitot tube principle,the flow velocity is measured,and the piezoresistive differential pressure sensor is used to measure the difference between the total hydro-pressure and the static pressure.The device has the characteristics of small size,light weight and portable measurement.From the practical measurement and application,it is shown that the measurement result of flow velocity is reliable and the accuracy is 0.5 %FS. |
