大部分結(jié)構(gòu)浮子流量計(jì)只能用于自下向上垂直流的管道安裝。浮子流量計(jì)可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500，雷諾數(shù)變化流量系數(shù)即保持常數(shù)，亦即流體粘度變化不影響流量系數(shù)。這數(shù)值遠(yuǎn)低于標(biāo)準(zhǔn)孔板等節(jié)流差壓式儀表比較低雷諾數(shù)104-105的要求。 </p> <p> 浮子流量計(jì)應(yīng)用局限于中小管徑，普通全流型浮子流量計(jì)不能用于大管徑，玻璃管浮子流量計(jì)比較大口徑100mm，金屬管浮子流量計(jì)為150mm，更大管徑只能用分流型儀表。 </p> <p> 使用流體和出廠標(biāo)定流體不同時(shí)，要作流量示值修正。液體用浮子流量計(jì)通常以水標(biāo)定，氣體用空氣標(biāo)定，如實(shí)際使用流體密度、粘度與之不同，流量要偏離原分度值，要作換算修正。插入式渦街流量計(jì)生產(chǎn)廠家隨著工業(yè)的發(fā)展，對(duì)流量測(cè)量的準(zhǔn)確度和范圍要求越來越高，為了適應(yīng)多種用途，各種類型的流量計(jì)相繼問世。</p><div

低維護(hù)量-市場(chǎng)上大多數(shù)的渦街流量計(jì)是采用取壓孔或插入式檢測(cè)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(hào)變?nèi)趸虿环€(wěn)定。良好的設(shè)計(jì)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(jiǎn)單的設(shè)計(jì)卻給實(shí)際使用帶來不便。因?yàn)橐坏└袘?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)。完善的設(shè)計(jì)應(yīng)該是將二者分開，這樣就可以單獨(dú)更換感應(yīng)部分，而無需將介質(zhì)排空。 </p> <p> 3. 渦街流量計(jì)容易受到振動(dòng)的干擾，設(shè)計(jì)精良的渦街流量計(jì)可以通過硬件和數(shù)字信號(hào)處理將干擾排除，從而得到穩(wěn)定的信號(hào)。 </p> <p> 4. 渦街流量計(jì)安裝的一麻煩是前后需要很長(zhǎng)的直管段，有些廠家可以提供在流量計(jì)內(nèi)部縮徑的設(shè)計(jì)，降低了用戶專門維渦街流量計(jì)配備直管段的需求。 </p><p style="text-indent:25px">流量計(jì)是由計(jì)量箱和裝在計(jì)量箱內(nèi)的一對(duì)橢圓齒輪，與上下蓋板構(gòu)成一個(gè)密封的初月形空腔(由于齒輪的轉(zhuǎn)動(dòng)，所以不是一定密封的)作為一次排量的計(jì)算單位。當(dāng)被測(cè)液體經(jīng)管道進(jìn)入流量計(jì)時(shí)，由于進(jìn)出口處產(chǎn)生的壓力差推動(dòng)一對(duì)齒輪連續(xù)旋轉(zhuǎn)，不斷地把經(jīng)初月形空腔計(jì)量后的液體輸送到出口處，橢圓齒輪的轉(zhuǎn)數(shù)與每次排量四倍的乘積即為被測(cè)液體流量的總量(原理見圖)。流量計(jì)主要是由殼體、計(jì)數(shù)器、橢圓齒輪和聯(lián)軸器(分磁性聯(lián)軸器和軸向聯(lián)軸器)等組成。電磁流量計(jì)、超聲波流量計(jì)、渦街流量計(jì)利用電氣原理工作，從而避免了機(jī)械流量計(jì)工作中需要更換的運(yùn)動(dòng)機(jī)件。</p><div

電磁流量計(jì)廣應(yīng)用于污水，氟化工，生產(chǎn)用水，自來水行業(yè)以及醫(yī)藥，鋼鐵等等諸多方面。由于原理決定了它只能測(cè)導(dǎo)電液體。雖說它在可靠性和穩(wěn)定性方面都比其它種類的流量計(jì)要好許多，但客戶在實(shí)際使用過程中，還是會(huì)發(fā)生一些問題，下面我就電磁流量計(jì)在選型和安裝上詳細(xì)說一下：一，和其它流量計(jì)一樣，雖然電磁流量計(jì)它的測(cè)量范圍比是30：1，比渦街流量計(jì)和差壓式流量計(jì)都要高，但也是有限制的，許多客戶定表時(shí)，常常把它和水表相比較，以為可以測(cè)量很低的流速，一般情況下，它只能測(cè)。所以定貨初期對(duì)流量范圍比要搞清楚。定貨時(shí)不能按原先管道口徑來定貨，比較好按你實(shí)際流量來定儀表口徑。二，和其它流量計(jì)一樣，電磁流量計(jì)對(duì)安裝前后直管道也有要求，只不過比其它類流量計(jì)要求更低，但關(guān)健一點(diǎn)要滿足：就是滿管，再滿管。不滿管的情況下容易引起流量計(jì)亂跳：三，和其它流量計(jì)一樣，電磁流量計(jì)也有防護(hù)等級(jí)，一般一體式的防護(hù)等級(jí)為IP65，分體式的為IP68(針對(duì)傳感器而言)，如果客戶對(duì)儀表安裝環(huán)境有要求，安裝地點(diǎn)在地下陰井或其它一些潮濕的地方，建議客戶選用分體式的。以免選錯(cuò)對(duì)儀表造成損害。一體型儀表將孔板和浮子流量計(jì)組裝在短管段上，直接裝到待測(cè)管道，安裝方便。插入式渦街流量計(jì)生產(chǎn)廠家</p><p style="text-indent:25px">應(yīng)用在石化行業(yè)的特殊環(huán)境中，需要堅(jiān)固耐用的設(shè)計(jì)以及防爆認(rèn)證;用戶對(duì)直管設(shè)計(jì)的科氏流量計(jì)的需求等。黑龍江浮子流量計(jì)</p><p> 渦街流量計(jì)便是依據(jù)卡門旋渦原理進(jìn)行封閉管道流體流量測(cè)量的新型流量計(jì)。因其具有良好的介質(zhì)適應(yīng)能力，無需溫度壓力補(bǔ)償即可直接測(cè)量蒸汽、空氣、氣體、水、液體的工況體積流量，配備溫度、壓力傳感器可測(cè)量標(biāo)況體積流量和質(zhì)量流量，是節(jié)流式流量計(jì)的理想替代產(chǎn)品。為提高渦街流量計(jì)的耐高溫及抗振動(dòng)性能，我公司新近開發(fā)出了改進(jìn)型渦街流量傳感器，因其獨(dú)特的結(jié)構(gòu)和選材使該傳感器可在高溫（350℃）、強(qiáng)振動(dòng)（≤1g）的惡劣工況下使用。在實(shí)際應(yīng)用中，往往比較大流量遠(yuǎn)低于儀表的上限值，隨著負(fù)荷的變化，小流量又往往會(huì)低于儀表的下限值，儀表并非工作在它的比較好工作段，為了解決這一問題，通常采用在測(cè)量處縮徑提高測(cè)量處的流速，并選用較小口徑的儀表以利于儀表的測(cè)量，但是這種變徑方式必須在變徑管與儀表間有長(zhǎng)度為15D以上的直管段進(jìn)行整流，使加工、安裝都不方便。我公司研制的縱斷面形狀為圓弧的LGZ變徑整流器，具有整流、提高流速及改變流速分布多重作用，其結(jié)構(gòu)尺寸小，*為工藝管內(nèi)徑的1/3，與渦街流量計(jì)作成一體，不*不需要另外附加一段直管段，還可以降低對(duì)工藝管直管段的要求，安裝非常方便。黑龍江浮子流量計(jì)</p><p
