一、概述
ARSLUB脈沖型渦街流量計(jì)是基于卡門渦街原理而研制成功的一種具有國(guó)際先進(jìn)水平的新型流量計(jì)。由于它具有其它流量計(jì)不可兼得的優(yōu)點(diǎn)，自七十年代以來(lái)得到了迅速發(fā)展，據(jù)有關(guān)資料顯示，現(xiàn)在日本，歐美等發(fā)達(dá)國(guó)家使用智能渦街流量計(jì)的比例大幅度上升，已廣泛應(yīng)用于各個(gè)領(lǐng)域。將在未來(lái)流量?jī)x表中占主導(dǎo)地位，是孔板流量計(jì)最理想的替代產(chǎn)品。
ARSLUB脈沖型渦街流量計(jì)適用于測(cè)量過(guò)熱蒸汽、飽和蒸汽、壓縮空氣和一般氣體、水和液體的質(zhì)量流量和體積流量。
二、特點(diǎn)
★ 結(jié)構(gòu)簡(jiǎn)單而牢固，無(wú)可動(dòng)部件，可靠性高，長(zhǎng)期運(yùn)行十分可靠。
★ 安裝簡(jiǎn)單，維護(hù)十分方便。
★ 檢測(cè)傳感器不直接接觸被測(cè)介質(zhì)，性能穩(wěn)定，壽命長(zhǎng)。
★ 輸出是與流量成正比的脈沖信號(hào)，無(wú)零點(diǎn)漂移，精度高。
★ 測(cè)量范圍寬，量程比可達(dá)
★ 壓力損失較小，運(yùn)行費(fèi)用低，更具節(jié)能意義。
★ 在一定的雷諾數(shù)范圍內(nèi)，輸出信號(hào)頻率不受流體物理性質(zhì)和組分變化的影響，儀表系數(shù)僅與漩渦發(fā)生體的形狀和尺寸有關(guān)，測(cè)量流體體積流量時(shí)無(wú)需補(bǔ)償，調(diào)換配件后一般無(wú)需重新標(biāo)定儀表系數(shù)。
★ 應(yīng)用范圍廣，蒸汽、氣體、液體的流量均可測(cè)量.
三、工作原理
ARSLUB脈沖型渦街流量計(jì)在測(cè)量管中垂直插入一個(gè)柱狀物時(shí)，流體通過(guò)柱狀物兩側(cè)就交替地產(chǎn)生有規(guī)則的旋渦(如下圖所示)，這種旋渦列被稱為卡門渦街�？ㄩT渦街的釋放頻率與流體的流動(dòng)速度及柱狀物的寬度有關(guān)，可用下式表示: f=St·v/d
式中: f-卡門渦街的釋放頻率
St-系數(shù)(稱為斯特羅哈數(shù))
v-流速
d-柱狀物的寬度
卡門渦街釋放頻率f和流速v成正比，因此通過(guò)測(cè)量卡門渦街釋放頻率就可算出瞬時(shí)流量。
斯特羅哈數(shù)是渦街流量計(jì)的重要系數(shù)。在曲線的St≈0.17的平直部分，旋渦的釋放頻率與流速成正比，所以檢出頻率f就可求得流速v，由v求出體積流量。
ARSLUB脈沖型渦街流量計(jì)的旋渦釋放頻率是由旋渦交替地作用于檢測(cè)傳感器(探頭)上的應(yīng)力通過(guò)在它內(nèi)部的壓電元件來(lái)檢出的。
