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。河北浮子流量計(jì)分流型浮子流量計(jì)的選用流速可比全流型高，液體流速可達(dá)2.5-3m/s，甚至高達(dá)4-5m/s。</p><div

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。 </p><p style="text-indent:25px">熱式流量計(jì)采用熱擴(kuò)散原理，熱擴(kuò)散技術(shù)是一種在苛刻條件下性能優(yōu)良、可靠性高的技術(shù)。熱式流量計(jì)有兩個(gè)溫度傳感器被置于介質(zhì)中時(shí)，其中一個(gè)傳感器被加熱到環(huán)境溫度以上的的溫度，另一個(gè)溫度傳感器用于感應(yīng)介質(zhì)溫度。介質(zhì)流速增加，介質(zhì)帶走的熱量增多，兩個(gè)溫度傳感器的溫度差將隨介質(zhì)的流速變化而變化，根據(jù)溫度差與介質(zhì)流速的比例關(guān)系，可得出流體的流量Q。熱式流量計(jì)目前絕大部分用于測(cè)量氣體，只有少量熱式流量計(jì)用于測(cè)量微小液體流量。浮子流量計(jì)的流量檢測(cè)元件是由一根自下向上擴(kuò)大的垂直錐形管和一個(gè)沿著錐管軸上下移動(dòng)的浮子組所組成。</p><div

差壓式孔板流量計(jì)是一款流量測(cè)量?jī)x表，主要應(yīng)用于液體、氣體流量測(cè)量，像蒸汽流量測(cè)量就是一個(gè)典型的測(cè)量工況，蒸汽在流量測(cè)量的過程中，由于自身溫度較高，測(cè)量難度大一般的流量計(jì)都無法勝任，而差壓式孔板流量計(jì)就可以有效的解決。差壓式孔板流量計(jì)的應(yīng)用領(lǐng)域非常廣，測(cè)量精度可達(dá)±0.5%，溫度可達(dá)700度，并且量程比為10：1，主要在氣體、蒸汽、液體的流量測(cè)量領(lǐng)域應(yīng)用較多，差壓式孔板流量計(jì)還有一個(gè)優(yōu)勢(shì)就是安裝方便，并且也不需要維護(hù)。有些透明管浮子流量計(jì)以就地指示為主，裝有接近開關(guān)，作流量上下限報(bào)警信號(hào)輸出。河北浮子流量計(jì)</p><p
