1．流量不但是控制化工生產(chǎn)及監(jiān)督設備工況的重要參數(shù)，也是物料流動工況特征參數(shù)之一，同時對確保正常生產(chǎn)，亦有很大意義。 2．流量又是車間、工廠實行企業(yè)經(jīng)濟核算的基礎依據(jù)，生產(chǎn)廠要準確地測出水、蒸汽、燃料氣、原料或動力消耗的情況，以加強企業(yè)管理，眉山流量儀表推薦，眉山流量儀表推薦。因此，操作人員對流量的測量，必須給予足夠的重視。由于流量測量的目的不同，對流量測量的要求也不同。前一種則要求儀表穩(wěn)定、靈敏，后一種則要求儀表準確、可靠。</p><div

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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">流量測量的方法很多，儀表的種類也很多，結(jié)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。</p><div
