适用范围
Part 4 of the standard considers the corrosive and erosive industrial environment to which land-based and off-shore, industrial-process measurement and control systems or parts of systems may be exposed during operation, during periods when they are installed but inactive, during storage or transportation. Maintenance and repair conditions are excluded from this part. The environmental influences considered in this part are limited to those which may directly affect performance of process-measurement and control systems or parts of such systems. Effects of the specific environmental conditions on personnel are not within the scope of this part. The appropriate values of the physical or chemical parameters listed here as well as the qualitative descriptions of the environment should be used to define local environments in which equipment is expected to operate, be transported and stored. Only conditions as such are considered; the resulting effects of these conditions on instrument performance are specifically excluded. Many environmental conditions listed in this part are difficult to classify so that a qualitative description is used to characterize the environment.

液体密度计使用注意

进样泵可便捷地进行更新  液体密度计安装使用:  用在腐蚀性介质时,接液体部分需选择相应防腐材质。还需注意是,即使是不和介质直接接触部分,也要考虑到其是否会受周围腐蚀性气体或过程渗出物侵蚀。另外,还要考虑到填充液可能泄漏会造成介质污染,应选择介质相容填充液,同时选用填充液时,要充分考虑其在过程下可能产生气化反应。  ...
