摘要
本文介绍了弯头流量计的试验台,通过对八种不同曲率和节数的常见90°弯头的试验,绘出了弯头的压差-风量曲线;另外,局部管件对弯头流量计精度的影响也进行了试验研究.
The paper introduces the experimental equipment for the 90°-bend flow meter. The author conducted a large number of experiments on eight sorts of standard 90°-bends with different bend curvatures different section numbers. Calculation graphs have been constructed, based on the experiments. Influences of fittings of ducts on its accuracy surrounding it are also shown in the paper.
