　　Points for Attention in Installation of Vortex Flowmeter on Site!Xi'an Huaheng Instrument:Vortex Street Flowmeter is mainly used to measure the flow of medium fluids in industrial pipelines,such as gases,liquids,vapors and other media.

 

　　其特點(diǎn)是壓力損失小,量程范圍大,精度高,在測量工況體積流量時(shí)幾乎不受流體密度、壓力、溫度、粘度等參數的影響。無(wú)可動(dòng)機械零件，因此可靠性高,維護量小。儀表參數能長(cháng)期穩定。

 

　　Its characteristics are small pressure loss,wide range and high accuracy.It is almost independent of the parameters such as fluid density,pressure,temperature and viscosity when measuring volume flow rate under working conditions.No mechanical parts,so high reliability,small maintenance.Instrument parameters can be stable for a long time.

 

　　渦街流量計采用壓電應力式傳感器,可靠性高,可在-20℃～+250℃的工作溫度范圍內工作。有模擬標準信號,也有數字脈沖信號輸出,容易與計算機等數字系統配套使用,是一種比較先進(jìn)、理想的流量?jì)x表。

 

　　Vortex flowmeter adopts piezoelectric stress sensor,which has high reliability and can work in the range of-20~250~C.It has analog standard signal and digital pulse signal output.It is easy to be used with computer and other digital systems.It is an advanced and ideal flow meter.

 

　　渦街流量計在選擇安裝現場(chǎng)和儀表的安裝位置時(shí)應注意以下幾點(diǎn)：

 

　　The following points should be paid attention to when choosing the installation site and the installation location of the instrument for vortex flowmeter:

 

　　1、盡可能避開(kāi)強電設備、高頻設備、強開(kāi)關(guān)電源設備。儀表的供電電源盡可能與這些設備分離。

　　2、避開(kāi)高溫熱源和輻射源的直接影響。

　　3、避開(kāi)高濕熱環(huán)境和強腐蝕氣氛的影響。

　　4、減小強振動(dòng)（特別是管道振動(dòng)）的影響。

　　5、選擇安裝、布線(xiàn)、維修方便的場(chǎng)所。

 

　　1.Avoid high-power equipment,high-frequency equipment and strong switching power supply equipment as far as possible.The power supply of the instrument should be separated from these devices as far as possible.

　　2.Avoid the direct influence of high temperature heat source and radiation source.

　　3.Avoid the influence of high humidity and heat environment and strong corrosive atmosphere.

　　4.Reduce the influence of strong vibration(especially pipe vibration).

　　5.Choose places where installation,wiring and maintenance are convenient.
