德国恩德斯豪斯E+H旗下产品，使用比较广，全国各地都有用到，所以我们要了解下E+H产品的一些知识，今天，我们给大家介绍的是E+H涡街流量计安装应注意的10个要点，希望能对客户朋友们有所帮助。
E+H涡街流量计安装注意的要点：
1、合理选择安装场所和环境。
避开强电力设备，高频设备，强电源开关设备；避开高温热源和辐射源的影响，避开强烈震动场所和强腐蚀环境等，同时要考虑安装维修方便。
2、上下游必须有足够的直管段。
若传感器安装点的上游在同一平面上有二个90。弯头，则：上游直管段≥25D，下游直管段≥5D。
若传感器安装点的上游在不同平面上有二个90。弯头，则：上游直管段≥40D，下游直管段≥5D。
调节阀应安装在传感器的下游5D以外处，若必须安装在传感器的上游，传感器上游直管段应不小于50D，下游应有不小于5D。
3、安装点上下游的配管应与传感器同心，同轴偏差应不小于0.5DN。
4、管道采取减振动措施。
传感器尽量避免安装在振动较强的管道上，特别是横向振动。若不得已要安装时，必须采取减振措施，在传感器的上下游2D处分别设置管道紧固装置，并加防振垫。
5．在水平管道上安装是流量传感器Z常用的安装方式。
测量气体流量时，若被测气体中含有少量的液体，传感器应安装在管线的较高处。
测量液体流量时，若被测液体中含有少量的气体，传感器应安装在管线的较低处。
6．传感器在垂直管道的安装。
测量气体流量时，传感器可以安装在垂直管道上，流向不限。若被测气体中含有少量的液体，气体流向应由下向上。
测量液体流量时，液体流向应由下向上：这样不会将液体重量额外附加在探头上。
7、传感器在水平管道的侧装。
无论测量何种流体，传感器可以在水平管道上侧装，特别是测量过热蒸汽，饱和蒸汽和低温液体，若条件允许Z好采用侧装，这样流体的温度对放大器的影响较小。
8．传感器在水平管道的倒装。
一般情况下不推荐用此安装方法。此安装方法不适用于测量一般气体、过热蒸汽。可用于测量饱和蒸汽，适用于测量高温液体或需经常清洗管道的情况。
9．传感器在有保温层管道上的安装。
测量高温蒸汽时，保温层Z多不能超过支架高度的三分之一。
10．测压点和测温点的选择。
根据测量的需要，需在传感器附近测量压力和温度时，测压点应在传感器下游的3-5D处，测温点应在传感器下游的6-8D
