低維護(hù)量-市場上大多數(shù)的渦街流量計是采用取壓孔或插入式檢測元件感應(yīng)漩渦，一旦介質(zhì)中雜質(zhì)嵌入取壓孔或感應(yīng)元件與表體間的縫隙，則造成信號變?nèi)趸虿环€(wěn)定。良好的設(shè)計應(yīng)該是沒有容易堵塞的部分，從而降低維護(hù)量。 </p> <p> 2. 感應(yīng)元件在線更換-某些廠家的感應(yīng)元件與渦街發(fā)生體合二為一，看似簡單的設(shè)計卻給實際使用帶來不便。因為一旦感應(yīng)部分失效，則需要將管道內(nèi)介質(zhì)排空泄壓后更換部件，影響生產(chǎn)，黑龍江管道式渦旋流量計制造商。完善的設(shè)計應(yīng)該是將二者分開，黑龍江管道式渦旋流量計制造商，這樣就可以單獨更換感應(yīng)部分，而無需將介質(zhì)排空。 </p> <p> 3. 渦街流量計容易受到振動的干擾，設(shè)計精良的渦街流量計可以通過硬件和數(shù)字信號處理將干擾排除，從而得到穩(wěn)定的信號，黑龍江管道式渦旋流量計制造商。 </p> <p> 4. 渦街流量計安裝的一麻煩是前后需要很長的直管段，有些廠家可以提供在流量計內(nèi)部縮徑的設(shè)計，降低了用戶專門維渦街流量計配備直管段的需求。實際上大部分浮子流量計同一儀表可用于液體也可用于氣體，結(jié)構(gòu)上是通用的。黑龍江管道式渦旋流量計制造商</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">液體流量計是根據(jù)卡門渦原理制造用于測量密封管道中液體、氣體、蒸汽流量的精密儀表。液體流量計是根據(jù)卡門渦原理制造用于測量密封管道中液體、氣體、蒸汽流量的精密儀表，由于檢測元件密封在檢測體內(nèi)，不被測介質(zhì)，且內(nèi)部無可動部件，無需進(jìn)行現(xiàn)場維護(hù)，因此深受廣大用戶的推崇，被廣用于紡織印染、石油、化工、冶金制藥、熱電、造紙，消防工業(yè)的計量管理及過程控制.有帶現(xiàn)場顯示3.6V電池供電和外供電源及輸出4-20mA;遠(yuǎn)傳顯示可配二次儀表液晶中文顯示，同時可帶溫度壓力補償。儀表直讀式，不需換算，使用方便，質(zhì)量可靠)。遼寧衛(wèi)生型渦旋流量計推薦一體型儀表將孔板和浮子流量計組裝在短管段上，直接裝到待測管道，安裝方便。</p><div

實際上大部分浮子流量計同一儀表可用于液體也可用于氣體，結(jié)構(gòu)上是通用的。只是我國浮子流量計行業(yè)標(biāo)準(zhǔn)等規(guī)定流量上限Qmax必須符合（1，，，4或6）×10nL/h的要求（n為正負(fù)整數(shù)或零），為液體（以水為表示）設(shè)計的儀表用于氣體（以空氣為表示）時，不符合上述要求，只能為氣體另行設(shè)計浮子和錐管，就分成液體和氣體兩種系列。國外有些制造廠同一儀表并列液、氣兩種流體的流量范圍，當(dāng)然流量值就不可能都是圓整值；國內(nèi)有些型號儀表也采用本辦法。但是液體用和氣體用設(shè)計還是有區(qū)別的，例如氣體儀表浮子設(shè)計得較輕，防浮子振蕩跳動的阻尼件結(jié)構(gòu)各異等。測量蒸汽只能用專門設(shè)計的金屬管浮子流量計或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件，例如增加帶散熱片的液體阻尼件，以減少浮子跳動；與指示轉(zhuǎn)換部分連接處隔以散熱片。 </p><p style="text-indent:25px">渦街流量計是根據(jù)卡門（Karman）渦街原理研究生產(chǎn)的，主要用于工業(yè)管道介質(zhì)流體的流量測量，如氣體、液體、蒸氣等多種介質(zhì)。其特點是壓力損失小，量程范圍大，精度高，在測量工況體積流量時幾乎不受流體密度、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，容易與計算機等數(shù)字系統(tǒng)配套使用，是一種比較先進(jìn)、理想的測量儀器。金屬管浮子流量計無錐管破裂的風(fēng)險。與玻璃管浮子流量計相比，使用溫度和壓力范圍寬。</p><div

電磁流量計內(nèi)的測量電極處于一個直流或交流電場內(nèi)，如果其環(huán)境不能有效地被屏蔽于一個無干擾的條件下，對測量有嚴(yán)重干擾。傳感器外殼接地與否，直接關(guān)系到測量的精度和穩(wěn)定性，接地導(dǎo)線必須不傳任何干擾電壓，因此電磁流量計要求有非?？煽康慕拥?，要做好接地屏蔽，否則就會產(chǎn)生干擾電流。然而電磁流量計接地的好處：若連接污水流量計的管道是（相對于被測介質(zhì)）絕緣性的則要用接地環(huán)，它的材質(zhì)應(yīng)根據(jù)被測介質(zhì)的腐蝕性選用。如果是聚四氟乙烯的傳感器，為了保護(hù)聚四氟乙烯的翻邊不受損傷，要選用接地環(huán)。金屬管錐形管可用于較高的介質(zhì)溫度和壓力，且無玻璃管浮子流量計錐管被擊碎的潛在危險。陜西管道式渦旋流量計制造商</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，如右圖所示，旋渦列在旋渦發(fā)生體下游非對稱地排列。 </p> <p> 渦街流量計是根據(jù)卡門（Karman）渦街原理測量氣體、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。并可作為流量變送器應(yīng)用于自動化控制系統(tǒng)中。 </p> <p> 渦街流量計是應(yīng)用流體振蕩原理來測量流量的，流體在管道中經(jīng)過渦街流量變送器時，在三角柱的旋渦發(fā)生體后上下交替產(chǎn)生正比于流速的兩列旋渦，旋渦的釋放頻率與流過旋渦發(fā)生體的流體平均速度及旋渦發(fā)生體特征寬度有關(guān)，可用下式表示： </p> <p> f=Stv/d </p> <p> 式中:f為旋渦的釋放頻率，Hz；v為流過旋渦發(fā)生體的流體平均速度，m/s；d為旋渦發(fā)生體特征寬度，m；St為斯特羅哈數(shù)，無量綱，它的數(shù)值范圍為0.14－0.27。 </p> <p> St是雷諾數(shù)的函數(shù)，St=f（l/Re）。 </p> <p> 當(dāng)雷諾數(shù)Re在102~105范圍內(nèi)，St值約為0.2，因此，在測量中，要盡量滿足流體的雷諾數(shù)在102~105，旋渦頻率f=0.2v/d。 </p> <p> 由此可知，通過測量旋渦頻率就可以計算出流過旋渦發(fā)生體的流體平均速度v，再由式q=vA可以求出流量q，其中A為流體流過旋渦發(fā)生體的截面積。黑龍江管道式渦旋流量計制造商</p><p
