流量或压力调节系统排污前，应先将自动切换到手动，保证调节阀的开度不变。对于差压变送器，排污前先将三阀组正负取压阀关死。排污阀下放置容器，慢慢打开正负导压管排污阀，使物料和污物进入容器，防止物料直接排入地沟，否则，一来污染环境，二来造成浪费。由于阀门质量差，排污阀门开关几次以后会出现关不死的问题，应急措施是加盲板，保证排污阀处于不泄漏，以免影响测量度。开启三阀组正负取压阀，拧松差压变送器本体上排污（排气）螺丝进行排污，排污完成拧紧螺丝。


一般每个传感器将会有两个温度范围，分别是工作范围和补偿范围。补偿范围包含在工作范围之内。工作范围是指在这个范围内，传感器通电后可以暴露在介质中而不会发生损坏。这并不表示当处于补偿范围以外的时候其性能也能达到标称的规格(温度系数)。补偿范围一般是在工作范围之内的一段更狭窄的范围。在这个范围内，传感器确保可以达到标称的规格。温度的改变通过两种方法影响传感器，其一是造成零点漂移，其二是影响整个量程的输出。



不锈钢反应釜以其优良的耐腐蚀性能和较低的价格，赢得越来越多客户的喜爱和信赖；因此在搅拌与反应釜结合处的密封的选择对于密封效果、使用安全、节约成本等都显得特别重要，现对如何选择合适的密封形式做出如下建议：1.首先要明确密封选择的依据：是釜内的工作压力，第二是工作物料的性质。还有一个就是设备的工作温度。其次要明确不锈钢反应釜所用密封的类别：反应釜所用密封即通常所说的轴封有两类，是填料密封，第二是机械密封，机械密封又分为单机封（即单端面机械密封）和双机封（即双端面机械密封），单机封全套还包括水夹套，双机封则较为复杂，除水夹套（必须有循环冷却水）外，还包括配套的支架、平衡罐等。如何选择合适的密封：在常温常压，物料没有挥发性也不易燃易爆的使用条件下，要选择填料密封；在压力小于4公斤，物料的易挥发性和易燃易爆性一般的使用条件下，就要选择单机封；在工作压力超过4公斤（但要小于1公斤），物料的易挥发性和易燃易爆性很强的使用条件下，则必须选择双机封。各种密封的优缺点：填料密封价格便宜，但只适合普通的使用条件和物料；单机封价格适中，可以在大多数使用条件下通用；双机封价格贵，但在苛刻的工作条件下必须使用。
