摘要
介绍了利用热线热膜风速计测量其空气校准器出口的速度分布,经过曲线拟合和积分,可以得出其平均速度和流量。空气校准器被改造成一台标准的气体流量计并成功地应用于其它小量程气体流量计的校准。
A measuring method of the velocity distribution at air calibrator exit of HWFA was introduced. The mean velocity and rate of flow can be obtained by curve fit and integral. The air calibrator was reformed as a standard air flowmeter, and it was used to calibrate other small range air flowmeter.
