摘要
在用出口侧管道进行风机性能试验时 ,常采用皮托管测流量。本文根据总压管和均速管原理设计了一种新型流量测量装置 。
Pitot tube is often used to measure airflow rate while fan performance test is carried out by the outlet test duct. A new type of device for measuring airflow rate is designed according to the principal of total pressure tube and the averaging velocity tube in this paper and its advantage in practical application is confirmed by a test.
