摘要
针对均速管流量计的总压及背压检测孔的数量和位置 ,检测杆的剖面形状等问题进行了讨论。详细介绍了均速管的几种结构形式 ,给出了实用流量测量的计算公式。分析了各种因素对测量精度的影响 。
Some issues pointing to the quantity and location of the detecting holes of the total and back pressures and the form of the profile of the detecting stem of the mean velocity tube flowmeter have been discussed.Several structure forms are presented in detail.The practical flow measurement calculation formula is proposed.Several factors effecting on the precission of measurement are analyzed.A proposal for developing this product is put forward finally.
