不銹鋼橢圓齒輪流量計(jì)的工作原理是液體推動(dòng)一對(duì)橢圓齒輪轉(zhuǎn)動(dòng)；每個(gè)腔體的容積是固定體積；齒輪轉(zhuǎn)速引出，傳感器發(fā)出同步脈沖計(jì)數(shù)，又被稱之為柴油流量計(jì)。橢圓齒輪的轉(zhuǎn)動(dòng)通過磁性密封聯(lián)軸器及傳動(dòng)減速機(jī)構(gòu)傳遞給計(jì)數(shù)器直接指示出流經(jīng)流量計(jì)的總量。若附加發(fā)信裝置后，再配以電顯示儀表可實(shí)現(xiàn)遠(yuǎn)傳只是瞬時(shí)流量或累積流量。

v錐流量計(jì)是一種差壓流量計(jì)，它的開發(fā)成功是差壓式流量測(cè)量質(zhì)的飛躍，它利用v錐體在流場(chǎng)中產(chǎn)生的節(jié)流效應(yīng)，通過檢測(cè)上下游壓差來測(cè)量流量。與普通節(jié)流件相比，它改變了節(jié)流布局，從中心孔節(jié)流改為環(huán)狀節(jié)流。實(shí)踐使用證明，v錐流量計(jì)與其他流量?jī)x表相比，具有長(zhǎng)期精度高、穩(wěn)定性好，受安裝條件局限小、耐磨損、測(cè)量范圍寬、壓損小、適合贓污介質(zhì)等優(yōu)點(diǎn)。而且v錐體本身作為流場(chǎng)
