All flow charts and scales shall be 0 -10 square root unless process requires linearization or linearization is a standard feature of the instrument. 原油计量是 质量流量计 ,可质量流量计的特性是线性的,在这里整出了个流量特性和量程是 0-10的平方根 ,我都晕了,大多数 流量仪表 是线性的,差压流量是特殊外,难道中石油这帮家伙在拷贝仪表要求,把控制阀的要求考到 流量计 上面了?还是我孤陋寡闻,欢迎大家讨论,共同提高,谢谢! 查看更多1个回答 . 4人已关注
