風扇及送風機市場上台灣亦在全世界上佔有一席之地，以2004年台灣的建準每年就有4500千台之電腦風扇之產量，因此在驗證其風扇流量之要求不得不有一個非常標準之裝置才能取得可信任之依據。
AMCA風洞普遍用在IT產業之CPU等散熱風扇性能測試用，一般氣體流量計之校正，不外乎送至國家標準檢驗局或以乾溼流量計校正，但其都有體積笨重，單價太高等之缺點。
此論文研究探討可行的流量校正方法並自製開發校正儀器設備。在小流量時，以氣體壓縮因子(compressibility factor)理論(PV=ZmRT)作出AMCA 風洞流量集氣校正桶，設計機械式氣體流量計之校正設備。為了精確計算量測通過風洞的氣體總流量，校正風洞中的流量計，將設計一圓筒型儲槽，氣體通過單位時間後，流經風洞的氣體將完全被收集儲存於儲槽中，於儲槽旁連接U型管利用管內液體高度差計算得到儲槽內之壓力，再利用理想氣體方程式計算單位時間內流經風洞之氣體流量。；在較高流量時，則以風速計與其他流量計校正。以理想氣體方程式為理論基礎，推算預測流量並與風洞顯示流量比較相對誤差。除此之外，風洞壓力測試點的位置以及針對尺寸更小的微型風扇測試是否會影響實驗結果也是一項課題，這些測試靈敏度分析都將在本文詳加討論。

Taiwan plays an important role in the whole world on the fan and forced draught blower market. Taiwan must set the standard for its flow of fan to make the dependable basis. AMCA wind-tunnel generally used in such fan function tests of heat dissipation as CPU of IT industry,etc. the correcting of the flow meter usually send to Inspection Bureau of the national standard but there are some disadvantages in high cost.
This thesis studies the feasible method to correct instrument and equipment.
In the small flow, we use the device with the compressibility factor Theory (PV =ZmRT) to correct the amount of air flow.
In order to calculate the total amount of air through wind tunnel, we precisely,we design a tank. After a while, the air passing through wind tunnel is selected into the tank. We observe the difference of height in water level in U monometer and calculate the pressure in the tank; In higher flow, we find other methods ,for example, wind velocity meter.
In base of ideal gas equation, we calculate error between the flow of predicting and the flow measured by the wind-tunnel. Finally, we discuss the pressure difference in different point.
