3、傳感器安裝前，法蘭凹槽內(nèi)必須放好密封圈。壓力和溫度測量點(diǎn)的位置，取壓點(diǎn)在傳感器下游3～5DN處，測溫點(diǎn)在下游5～8DN處，攀枝花渦街流量計價格。 </p> <p> 4、測量高溫介質(zhì)時，切勿用隔熱材料把傳感器連接桿周圍包起來。 </p> <p> 5、連接傳感器的屏蔽電纜走向，應(yīng)盡可能遠(yuǎn)離強(qiáng)電磁場的干擾場合。***不允許與高壓電纜一起敷設(shè)，屏蔽電纜要盡量縮短，并且不得盤卷，以減少分布電感，比較大長度不應(yīng)超過200米，攀枝花渦街流量計價格，攀枝花渦街流量計價格。 </p> <p> 6、安裝傳感器前，管道必須進(jìn)行清洗。沖掉管內(nèi)的雜質(zhì)，避免通流后堵塞傳感器。測量液體的管道必須充滿被測液體，防止氣泡的干擾。 </p> <p> 測量氣體的管道為防止儲積液的干擾。安裝位置如圖五所示。高溫高壓下更換探頭體時，必須安全操作，做好高溫防護(hù)。降溫降壓后在安全條件下方可更換探頭。 </p><div style="width:100%;text-align:

傳感器應(yīng)安裝在水平、垂直、傾斜(液體流向自下而上)的與其通徑相同的管道上。傳感器的上游和下2游應(yīng)配置一定長度的直管段，其長度應(yīng)符合前直管段15～**，后直管段5～1OD的要求。 </p> <p> 安裝液體傳感器的附近管道內(nèi)應(yīng)充滿被測液體。 </p> <p> 傳感器應(yīng)避免安裝在有強(qiáng)烈機(jī)械振動的管道上。 </p> <p> 直管段的內(nèi)徑盡可能與傳感器通徑一致，若不能一致，應(yīng)采用比傳感器通徑略大的管道，誤差要≤3%，并不超過5mm。 </p> <p> 傳感器應(yīng)避免安裝在有較強(qiáng)電磁場干擾、空間小和維修不方便的場合。 </p><div style="width:100%;text-align: center;"><img style="max-width:

渦街流量計正確選型才能保證渦街流量計更好的使用。選用什么種類的渦街流量計應(yīng)根據(jù)被測流體介質(zhì)的物理性質(zhì)和化學(xué)性質(zhì)來決定?使渦街流量計的通徑、流量范圍、襯里材料、電極材料和輸出電流等都能適應(yīng)被測流體的性質(zhì)和流量測量的要求。 </p> <p> 1、精密功能檢查 </p> <p> 精度等級和功能根據(jù)測量要求和使用場合選擇儀表精度等級，做到經(jīng)濟(jì)合算。比如用于貿(mào)易結(jié)算、產(chǎn)品交接和能源計量的場合，應(yīng)該選擇精度等級高些，如1.0級、0.5級，或者更高等級; </p> <p> 用于過程控制的場合，根據(jù)控制要求選擇不 </p> <p> 同精度等級;有些**是檢測一下過程流量，無需做精確控制和計量的場合，可以選擇精度等級稍低的，如1.5級、2.5級，甚至 </p> <p> 4.0級，這時可以選用價格低廉的插入式渦街流量計。 </p> <p> 2、可測量的介質(zhì) </p> <p> 測量介質(zhì)流速、儀表量程與口徑 </p> <p> 測量一般的介質(zhì)時，渦街流量計的滿度流量可以在測量介質(zhì)流速0.5—12m/s范圍內(nèi) 選用，范圍比較寬。選擇儀表規(guī)格(口徑)不一 </p> <p> 定與工藝管道相同，應(yīng)視測量流量范圍是否在流速范圍內(nèi)確定，即當(dāng)管道流速偏低，不能滿足流量儀表要求時或者在此流速下測量準(zhǔn) </p> <p> 確度不能保證時，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測量結(jié)果。 </p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/313082.html</p></div></div></div></div></div><div id="jipmjah" class="page-right twoColRt"><div
