摘要
一种设计成测量标尺随风流压力的变化而上下移动的风压测量装置,能同时测出风流的全压、动压和静压。与U型压力计相比,可减少测量时间70％。
A kind of ventilation pressure measuring device, its scale can move up-and-down in according with the change of ventilation pressure, can measure simultaneously the total pressure, dynamic pressure and static pressure. It spends only 30 persent of the time that a U type manometr needs
