渦街流量計(jì)是根據(jù)卡門(mén)（Karman）渦街原理研究生產(chǎn)的測(cè)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(cè)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，攀枝花渦街流量計(jì)銷(xiāo)售，精度高，在測(cè)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(wú)可動(dòng)機(jī)械零件，因此可靠性高，維護(hù)量小。儀表參數(shù)能長(zhǎng)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(hào)，也有數(shù)字脈沖信號(hào)輸出，攀枝花渦街流量計(jì)銷(xiāo)售，攀枝花渦街流量計(jì)銷(xiāo)售，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(cè)量?jī)x器。

</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(cè)量點(diǎn)的位置，取壓點(diǎn)在傳感器下游3～5DN處，測(cè)溫點(diǎn)在下游5～8DN處。 </p> <p> 4、測(cè)量高溫介質(zhì)時(shí)，切勿用隔熱材料把傳感器連接桿周?chē)饋?lái)。 </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(chǎng)的干擾場(chǎng)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(pán)卷，以減少分布電感，比較大長(zhǎng)度不應(yīng)超過(guò)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(cè)量液體的管道必須充滿被測(cè)液體，防止氣泡的干擾。 </p> <p> 測(cè)量氣體的管道為防止儲(chǔ)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。德陽(yáng)渦街流量計(jì)報(bào)價(jià)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

渦街流量計(jì)正確選型才能保證渦街流量計(jì)更好的使用。選用什么種類(lèi)的渦街流量計(jì)應(yīng)根據(jù)被測(cè)流體介質(zhì)的物理性質(zhì)和化學(xué)性質(zhì)來(lái)決定?使渦街流量計(jì)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(cè)流體的性質(zhì)和流量測(cè)量的要求。 </p> <p> 1、精密功能檢查 </p> <p> 精度等級(jí)和功能根據(jù)測(cè)量要求和使用場(chǎng)合選擇儀表精度等級(jí)，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(jì)量的場(chǎng)合，應(yīng)該選擇精度等級(jí)高些，如1.0級(jí)、0.5級(jí)，或者更高等級(jí); </p> <p> 用于過(guò)程控制的場(chǎng)合，根據(jù)控制要求選擇不 </p> <p> 同精度等級(jí);有些**是檢測(cè)一下過(guò)程流量，無(wú)需做精確控制和計(jì)量的場(chǎng)合，可以選擇精度等級(jí)稍低的，如1.5級(jí)、2.5級(jí)，甚至 </p> <p> 4.0級(jí)，這時(shí)可以選用價(jià)格低廉的插入式渦街流量計(jì)。 </p> <p> 2、可測(cè)量的介質(zhì) </p> <p> 測(cè)量介質(zhì)流速、儀表量程與口徑 </p> <p> 測(cè)量一般的介質(zhì)時(shí)，渦街流量計(jì)的滿度流量可以在測(cè)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(cè)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?jī)x表要求時(shí)或者在此流速下測(cè)量準(zhǔn) </p> <p> 確度不能保證時(shí)，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測(cè)量結(jié)果。 </p><p> 技術(shù)指標(biāo) </p> <p>
