style="text-indent:25px">流量儀表品種如此之多的原因就在于至今還沒找到一種對任何流體、任何量程、任何流動狀態(tài)以及任何使用條件都適用的流量儀表。流量計種類，流量計選型，流量計價格，流量計原理，流量計安裝，流量計廠家是使用者一直很關注的問題。所以在選用流量儀表時，要進行周密的分析與比較，選擇適宜的流量儀表以達到預期的測量目的。電磁流量計是根據(jù)法拉第電磁感應定律制成的一種測量導電性液體的儀表。電磁流量計由傳感器、轉換器、電纜連接線三部分組成，缺一不可。如果電纜連接線很短，安裝在流量計殼體內(nèi)。瀘州流量儀表哪家專業(yè)</p><div

2.非接觸式測量：將帶磁性的超聲波流量計傳感器吸附在管道外壁，即可完成流量測量； 3.測量范圍大：選用不同型號的傳感器，可實現(xiàn)口徑DNl5-DN6000mm管道流量的測量； 4.支持中文英文菜單：不同版本的流量計，可支持中文或英文菜單，方便快捷； 5.充電電源：內(nèi)置大容量鎳氫充電電池，可支持流量計連續(xù)工作20小時以上； 6.內(nèi)置打印機：即可實現(xiàn)即時屏幕打印，還可以定時打印提前設定的多達20余項的測量結果； 7.內(nèi)置數(shù)據(jù)記錄器：可將提前設定的多達20余項的測量結果上傳至計算機或聯(lián)網(wǎng)通訊。</p><p style="text-indent:25px">流量儀表(流量計)的一般選型可以從五個方面進行考慮，這五個方面為流量計儀表性能方面、流體特性方面、安裝條件方面、環(huán)境條件方面和經(jīng)濟因素方面。五個方面的詳細因素如下： 1、儀表性能方面：準確度、重復性、線性度、范圍度、流量范圍、信號輸出特性、響應時間、壓力損失等； 2、流體特性方面：溫度、壓力、密度、粘度、化學腐蝕、磨蝕性、結垢、混相、相變、電導率、聲速、導熱系數(shù)、比熱容，等熵指數(shù)； 3、安裝條件方面：管道布置方向，流動方向，檢測件上下游側直管段長度、管道口徑，維修空間、電源、接地、輔助設備(過濾器、消氣器)、安裝、等； 4、環(huán)境條件方面：環(huán)境溫度、濕度、電磁干擾、安全性、防爆、管道振動等； 5、經(jīng)濟因素方面：儀表購置費、安裝費、運行費、校驗費、維修費、儀表使用壽命、備品備件等。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州流量儀表哪家專業(yè),流量儀表"

style="text-indent:25px">流量測量的方法很多，儀表的種類也很多，結合流量的定義，常用的流量測量方法可歸納為容積法，流速法和質(zhì)量流量法等。如果流體是以固定體積從流量計中逐次排放流出，則對排放的次數(shù)計數(shù)，就可以求得通過儀器的流體總量。若測量排放的頻率，即可顯示流量。這種方法叫做容積法。如刮板流量計。橢圓齒輪流量計和標準體積管等，都是按此原理工作的。這類儀表所顯示的是體積流量的總量。容積法的特點是流動狀態(tài)對測量的影響較小，精確度較高，這類流量計一般不宜用于測量高溫高壓流體和臟污介質(zhì)的流量，測量流量的上限也不大。瀘州流量儀表哪家專業(yè)</p><p style="text-indent:25px">瀘州流量儀表哪家專業(yè)</p><p style="text-indent:25px">量儀表(流量計)的選型對儀表能否成功使用往往起著很重要的作用，由于被測對象的復雜狀況以及儀表品種繁多、性能指標各使得儀表的選型感到困難。沒有一種十全十美的流量計，各類儀表都有各自的特點，選型的目的就是在眾多的品種中揚長避短選擇自己**合適的流量計儀表。流量計儀表選型的步驟如下： 1、依據(jù)流體種類及五個方面考慮因素初選可用儀表類型(要有幾種類型以便進行選擇)； 2、對初選類型進行資料及價格信息的收集，為深入的分析比較準備條件； 3、采用淘汰法逐步集中到1～2種類型，對五個方面因素要反復比較分析**終確定預選目標。瀘州流量儀表哪家專業(yè)</p><p
