Pressure tapping points on either side of the seat provide the means for flow measurement.

压力变送器应尽量安装在温度梯度和温度波动小的测压点上，同时避免强振动和冲击。
It is suggested the pressure transmitter be mounted on measuring point with lower temperature gradient and temperature fluctuation, meanwhile avoid vibration and impact.

风洞顶壁上最佳测压点非定常压力迟滞环方向与风洞底壁上对应最佳测压点非定常压力迟滞方向相反。
The hysteresis direction at the optimum measuring pressure point on top wall is opposite to that on bottom wall.
