   涡街流量计可广泛用于大、中、小型各种管道给排水、工业循环、污水处理,油类及化学试剂以及压缩空气、饱和及过热蒸汽、天然气及各种介质流量的计量并可作为流量变送器应用于自动化控制系统中,使用寿命长。

 
  Vortex flowmeter can be widely used in large,medium and small pipeline water supply and drainage,industrial cycle,sewage treatment,oil and chemical reagents,as well as the flow measurement of compressed air,saturated and superheated steam,natural gas and various media.It can also be used as flow transmitter in automatic control system with long service life.
 
 
  涡街流量计安装注意的要点:
 
  Points for Attention in Installation of Vortex Flowmeter:
 
  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。
 
  1.Reasonable selection of installation site and environment.
  Avoid strong power equipment,high frequency equipment,strong power switch equipment,avoid the impact of high temperature heat and radiation sources,avoid strong vibration and strong corrosion environment,and consider the installation and maintenance convenience.
 
  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。
 
  2.The upstream and downstream must have enough straight pipe sections.
  If there are two 90 degree elbows in the upstream of the sensor installation point on the same plane,the upstream straight pipe section is more than 25D and the downstream straight pipe section is more than 5D.If the upstream of the sensor installation point has two 90 on different planes.Elbow,then:upstream straight section(>40D),downstream straight section(>5D).The regulating valve should be installed outside 5D downstream of the sensor.If it must be installed upstream of the sensor,the upstream straight pipe section of the sensor should be no less than 50D,and the downstream should be no less than 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。
 
  3.The downstream piping at the installation point should be concentric with the sensor,and the coaxial deviation should be no less than 0.5DN.
 
  4、管道采取减振动措施。
  涡街流量计的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。
 
  4.Vibration reduction measures should be taken for pipelines.
  The sensor of the vortex flowmeter should be installed in the pipeline with strong vibration,especially the transverse vibration.If it has to be installed,vibration reduction measures must be taken.Pipeline fastening devices and anti-vibration pads should be installed at the upstream and downstream 2D of the sensor respectively.
 
  5.在水平管道上安装是流量传感器最常用的安装方式。
  测量气体流量时,若被测气体中含有少量的液体,涡街流量计的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。
 
  5.Installation on horizontal pipeline is the most commonly used installation mode of flow sensor.
  When measuring the gas flow rate,if the measured gas contains a small amount of liquid,the sensor of the vortex flowmeter should be installed at the higher part of the pipeline.When measuring liquid flow,if the measured liquid contains a small amount of gas,the sensor should be installed at the lower part of the pipeline.
 
  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。
 
  6.Installation of sensors in vertical pipes.
  When measuring gas flow rate,the sensor can be installed in a vertical pipe with unlimited flow direction.If the measured gas contains a small amount of liquid,the flow direction of the gas should be from bottom to top.When measuring the flow of liquid,the flow direction of liquid should be from bottom to top:this will not add additional liquid weight to the probe.
 
  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,若条件允许最好采用侧装,这样流体的温度对放大器的影响较小。
 
  7.Side mounting of sensor in horizontal pipeline.
  No matter what kind of fluid is measured,the sensor can be side-mounted in horizontal pipeline,especially in superheated steam,saturated steam and low temperature liquid.If conditions permit,it is better to use side-mounted,so the temperature of the fluid has less influence on the amplifier.
 
  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。
 
  8.Inversion of sensors in horizontal pipes.
  Normally,this installation method is not recommended.This installation method is not suitable for measuring general gas and superheated steam.It can be used to measure saturated vapor,to measure high temperature liquid or to frequently clean pipelines.
 
  9.传感器在有保温层管道上的安装。
  测量高温蒸汽时,保温层最多不能超过支架高度的三分之一。
 
  9.Installation of sensors on insulated pipes.
  When measuring high temperature steam,the insulation layer should not exceed one third of the height of the support.
 
  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处。
 
  10.Selection of pressure and temperature measuring points.
  According to the need of measurement,when measuring pressure and temperature near the sensor,the pressure measuring point should be 3-5D downstream of the sensor,and the temperature measuring point should be 6-8D downstream of the sensor.
