西门子电磁流量计/超声波流量计7ME系列
电磁流量计用于测量导电液体的体积流量，也适用于含或不含悬浮颗粒物的液体，或淤泥、浆料等粘稠的介质。
超声波流量计测量均匀的导电或非导电的液体和气体，高负荷热水区域供热的精确、高分辨率能量测量，即能量站，热交换站或传送网络。除了标准的体积流量，它还可以提供介质性质和温度等信息。
西门子压力测量仪表（压力变送器）7MF系列
SITRANS P 是全系列测量压力、差压和绝压的变送器。SITRANS P 全系列
变送器测量精度高，结构坚固。同时，模块化的设计更是保证了其简单易用，功能强大，具备完善的安全认证。简而言之，设计和实践证明其适用于各种应用场合。
西门子6DR5系列智能电气阀门定位器与常规产品相比，有许多独特而实用的优点，例如：
1、安装简单，自动初始化（零位和行程范围自动调整）
2、操作简便
3、使用三个按键和双行LCD 显示可实现简捷的操作和编程
4、通过SIMATIC PDM编程；高质量控制归功于在线自适应程序
5、稳态操作时耗气量可忽略
6、“紧密关闭”功能（确保对阀座的最大定位压力）
7、通过简单的组态可以实现众多功能（例如参量化和极限值）
8、用于阀和执行器的自诊断
9、直行程和角行程执行机构采用同一型号的阀门定位器
10、可动部件少，因此对振动不敏感
11、在极端的外界环境中，可以选择外部非接触式位置传感器
