常用流量計(jì)參數(shù)簡(jiǎn)單比較：渦輪流量計(jì) 當(dāng)流體流經(jīng)渦輪流量計(jì)時(shí)，流體使轉(zhuǎn)子旋轉(zhuǎn)。轉(zhuǎn)子的旋轉(zhuǎn)速度與流體的速度相關(guān)。通過轉(zhuǎn)子感受到的流體平均流速,推導(dǎo)出流量或總量。渦輪流量計(jì)可精確地測(cè)量潔凈的液體和氣體。像PD流量計(jì)，渦輪流量計(jì)也會(huì)產(chǎn)生不可恢復(fù)的壓力誤差，也需要移動(dòng)部件。 超聲流量計(jì) 傳播時(shí)間法和多普勒效應(yīng)法是超聲流量計(jì)常采用的方法，用以測(cè)量流體的平均速度。像其他速度測(cè)量計(jì)一樣，是測(cè)量體積流量
