五孔球测量流场时，传统方法是采用液柱法测孔压．文中介绍采用压力（差压）传感器测了孔压并通过计算机进行数据采集和数据处理的方法．使用情况表明，此方法较传统方法提高了测量精度，加快了测量速度，省人力，并能方便快捷地进行数据处理． Five-hole ball measuring flow field, the traditional method is to use liquid column method to measure pore pressure. This paper describes the use of pressure (differential pressure) sensor measured pore pressure and computer data acquisition and data processing methods. The usage shows that this method improves the measurement accuracy, accelerates the measurement speed and saves manpower compared with the traditional method, and can process the data conveniently and quickly.
