【国际原子能机构国际核情报系统报告INIS-mf-5940报道】气体流量仪在诸如化工和核工艺中通常用来控制和调节生产过程,但在某些方面的应用,它们还存在一些缺点,特别是在连续生产过程中。例如,浮子流量计,其精确度取决于浮子所在的管道的清洁程度。在极端情况下,这种流量计可能完全失效,而其清洗工作却是十分复杂的。有些流量计测量的结果只能在流量计本 [International Atomic Energy Agency Nuclear Information System Report INIS-mf-5940] Gas flow meters are commonly used to control and regulate manufacturing processes, such as in chemical and nuclear processes, but they have some drawbacks in certain applications, particularly In the continuous production process. For example, a float flowmeter whose accuracy depends on the cleanliness of the pipe on which the float is located. In extreme cases, this flowmeter may be completely ineffective, and its cleaning is very complicated. Some flowmeter measurement results only in the flow meter
