質量流量控制器使用注意問題

發布日期:2022-05-29 點擊率:36

  大家知道質量流量控制器在使用中要注意哪些問題呢?下面給大家介紹下。

  1、測量氣體流量時必須保持恒定的比定壓熱容,因此不能用于測量成分變化的氣體。

  2、被測量的氣體必須是干燥的,質量流量控制器測量時的氣體工況不要接近臨界點,以免引起液化相變等不穩定狀態。

  3、測量易汽化液體應注意流量計的加熱對被測液體的影響,必要時選擇有制冷元件(負加熱元件)的質量流量控制器。

  4、液體中不能混入氣泡,不能用于混相流或可能產生相變的流體。

  5、應用于含有煙霧和塵埃氣體的管線,必要時在儀表裝分離器或過濾器。

  注意了以上這些事項,可降低質量流量控制器的測量誤差,測量結果更準確。
