PD流量計,在流量儀表中是精度比較高的一類。它利用機(jī)械測量元件把流體連續(xù)不斷地分割成單個已知的體積部分,根據(jù)測量室逐次重復(fù)地充滿和排放該體積部分流體的次數(shù)來測量流體體積總量。 </p> <p> 容積式流量計按其測量元件分類,可分為橢圓齒輪流量計、刮板流量計、雙轉(zhuǎn)子流量計、旋轉(zhuǎn)活塞流量計、往復(fù)活塞流量計、圓盤流量計、液封轉(zhuǎn)筒式流量計、濕式氣量計及膜式氣量計等。 </p> <p> 優(yōu)點(diǎn): </p> <p> (1)計量精度高; </p> <p> (2)安裝管道條件對計量精度沒有影響; </p> <p> (3)可用于高粘度液體的測量; </p> <p> (4)范圍度寬; </p> <p> (5)直讀式儀表無需外部能源可直接獲得累計,總量,清晰明了,操作簡便。 </p> <p> 缺點(diǎn): </p> <p> (1)結(jié)果復(fù)雜,體積龐大; </p> <p> (2)被測介質(zhì)種類、口徑、介質(zhì)工作狀態(tài)局限性較大; </p> <p>
