在石油、化工系统大量使用流量计。自从在开封、遵义分别召开有汞流量计改造经验交流会以后,全国各地许多厂矿都先后开展了这一工作。各单位在总结介绍经验时,多半偏重于结构和调校方面,而缺少理论分析。许多单位在绕制弹簧时,完全采用试的办法,往往很难奏效。这主要是因为弹簧钢丝的直径及弹簧参数的选择完全采用试验办法来确定,缺乏理论指导,没有定量的分析。现将我 Massive use of flowmeters in petroleum and chemical systems. Since Kaifeng, Zunyi have convened a exchange of mercury flow meter experience exchange, many factories and mines across the country have carried out this work. When summarizing and introducing experience, most units focused on structure and adjustment, but lacked theoretical analysis. When many units are wound around springs, they are often difficult to test because they are fully tested. This is mainly because the selection of the diameter of the spring wire and the spring parameter is entirely determined by the experimental method, lacking of theoretical guidance and without quantitative analysis. Now I am
