摘要(Abstract)：

为解决因风道布置不合理引起的流场紊乱和难以准确测量风量的问题,对一次风量测量装置进行改造,将混风道测量装置由热导式气体流量计改为多点差压,冷、热风道采用热导式测量,取得了较好的效果。
Improvement of primary air flow meter is performed in order to solve the problem of flow field disorder and the difficulty in air flow measurement caused by unreasonable layout of air duct.Multipoint differential pressure flow meter is used for mixed air duct instead of thermal conduction flow meter and thermal conduction flow meter for cold and hot air ducts.And desired effect is achieved.
