■ 流量計(jì)在水平管道上的安裝Installation of flowmeter on horizontal pipelines
▲ 在水平管道上安裝是流量計(jì)常用的安裝方式
installation of flowmeter on horizontal pipelines is the most common installation mode
▲ 測(cè)量氣體流量時(shí),若被測(cè)氣體中含有少量的液體,流量計(jì)應(yīng)安裝在管線(xiàn)的較高處.
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.
▲ 測(cè)量液體流量時(shí),若被測(cè)液體中含有少量的氣體,流量計(jì)應(yīng)安裝在管線(xiàn)的較低處
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.
■ 流量計(jì)在垂直管道的安裝
Installation of flowmeter on vertical pipelines
▲ 測(cè)量氣體流量時(shí),流量計(jì)可以安裝在垂直管道上,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.
▲ 若被測(cè)氣體中含有少量的液體,氣體流向應(yīng)由上而下.
if there is small amount of liquid in the measured gas, the gas shall flow upwardly from the lower position.
▲ 測(cè)量液體流量時(shí),液體流向應(yīng)由下向上
When the flowmeter is used to measure liquid flow,the liquid shall flow upwardly from the lower position.
■ 流量計(jì)和顯示儀運(yùn)行前的準(zhǔn)備工作
Preparation before the operation of flowmeter and display meter.
▲ 仔細(xì)檢查流量計(jì)的安裝,接線(xiàn)等是否正確無(wú)誤.
▲ 接通顯示儀電源,觀察顯示儀是否有流量顯示.
▲ 緩慢打開(kāi)閥門(mén),到一個(gè)較小壓力時(shí)停止,觀察傳感器周?chē)欠裼行孤冬F(xiàn)象,并觀察顯示儀是否有流量顯示
▲ .若情況正常,開(kāi)大閥門(mén),穩(wěn)定一段時(shí)間后,觀察儀表顯示的流量是否正常.
▲ 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.
