■ 流量计在水平管道上的安装Installation of flowmeter on horizontal pipelines
▲ 在水平管道上安装是流量计常用的安装方式
installation of flowmeter on horizontal pipelines is the most common installation mode
▲ 测量气体流量时,若被测气体中含有少量的液体,流量计应安装在管线的较高处.
When the flowmeter is used to measure gas flow,if there is small amount of liquid in the gas,the flowmeter shall be installed at the higher position of the pipeline.
▲ 测量液体流量时,若被测液体中含有少量的气体,流量计应安装在管线的较低处
When the flowmeter is used to measure liquid flow,if there is small amount of gas in the liquid,the flowmeter shall be installed at the lower position of the pipeline.
■ 流量计在垂直管道的安装
Installation of flowmeter on vertical pipelines
▲ 测量气体流量时,流量计可以安装在垂直管道上,流向不限.
When the flowmeter is used to measure gas flow,the flowmeter can be installed on the vertical pipelineａnd the flow direction is not limited.
▲ 若被测气体中含有少量的液体,气体流向应由上而下.
if there is small amount of liquid in the measured gas, the gas shall flow upwardly from the lower position.
▲ 测量液体流量时,液体流向应由下向上
When the flowmeter is used to measure liquid flow,the liquid shall flow upwardly from the lower position.
■ 流量计和显示仪运行前的准备工作
Preparation before the operation of flowmeter and display meter.
▲ 仔细检查流量计的安装,接线等是否正确无误.
▲ 接通显示仪电源,观察显示仪是否有流量显示.
▲ 缓慢打开阀门,到一个较小压力时停止,观察传感器周围是否有泄露现象,并观察显示仪是否有流量显示
▲ .若情况正常,开大阀门,稳定一段时间后,观察仪表显示的流量是否正常.
▲ Check the installation of the flowmeter carefully,ａnd whether the wiring etc,is done in correct way,
▲ Connect with the power supply of the display meter,ａnd observe whether there is flow display on the display meter.
▲ Open the value slowly and stop when the pressure is relatively low.Observe whether there is leakage around the sensor,ａnd observe whether there is flow display on the display meter.
▲ If they are in normal condition,further open the value,ａnd after it is stabilized for a while,observe whether the flow displayed on the meter is normal.
