渦街流量計(jì)是根據(jù)卡門（Karman）渦街原理研究生產(chǎn)的測量氣體、蒸汽或液體的體積流量、標(biāo)況的體積流量或質(zhì)量流量的體積流量計(jì)。主要用于工業(yè)管道介質(zhì)流體的流量測量，如氣體、液體、蒸汽等多種介質(zhì)。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(shù)的影響。無可動機(jī)械零件，因此可靠性高，維護(hù)量小。儀表參數(shù)能長期穩(wěn)定。渦街流量計(jì)采用壓電應(yīng)力式傳感器，可靠性高，可在-20℃～+250℃的工作溫度范圍內(nèi)工作。有模擬標(biāo)準(zhǔn)信號，也有數(shù)字脈沖信號輸出，容易與計(jì)算機(jī)等數(shù)字系統(tǒng)配套使用，是一種比較先進(jìn)、理想的測量儀器。 </p> <p> <br /> </p><p> 渦街流量計(jì)也稱之為旋渦流量計(jì)或卡門渦街流量計(jì) </p> <p>

</p> <p> <p> 原理 </p> <p> 在流體中設(shè)置三角柱型旋渦發(fā)生體，則從旋渦發(fā)生體兩側(cè)交替地產(chǎn)生有規(guī)則的旋渦，這種旋渦稱為卡門旋渦，旋渦列在旋渦發(fā)生體下游非對稱地排列。 </p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p>

</p> <p> 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。 </p> <p> 4、測量高溫介質(zhì)時(shí)，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。 </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(shí)，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。綿陽渦街流量計(jì)哪家專業(yè)</p><p style="text-indent:25px">綿陽渦街流量計(jì)哪家專業(yè)</p><p> 安裝條件 </p> <p> 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。綿陽渦街流量計(jì)哪家專業(yè)</p><p
