橢圓齒輪流量計(jì)流量信號(hào)(即橢圓齒輪的旋轉(zhuǎn)速度n)的顯示，有就地顯示和遠(yuǎn)傳顯示兩種。就地顯示將齒輪的轉(zhuǎn)動(dòng)通過(guò)一系列的減速及調(diào)整轉(zhuǎn)速比機(jī)構(gòu)之后，直接與儀表面板上的指示針相連，并經(jīng)過(guò)機(jī)械式計(jì)數(shù)器進(jìn)行總量的顯示。遠(yuǎn)傳顯示主要是通過(guò)減速后的齒輪帶動(dòng)永久磁鐵旋轉(zhuǎn)，使得彈簧繼電器的觸點(diǎn)以與永久磁鐵相同的旋轉(zhuǎn)頻率同步地閉合或斷開(kāi)，從而發(fā)出一個(gè)個(gè)電脈沖遠(yuǎn)傳給另一顯示儀表.橢圓齒輪流量計(jì)計(jì)量精度高，適用于高粘度介質(zhì)流量的測(cè)量，但不適用于含有固體顆粒的流體，如果被測(cè)液體介質(zhì)中夾雜有氣體時(shí)，也會(huì)引起測(cè)量誤差。通常橢圓齒輪流量計(jì)的精度可達(dá)0.5級(jí)，是一種較為準(zhǔn)確的流量計(jì)量?jī)x表，但是，如果使用時(shí)被測(cè)介質(zhì)的流量過(guò)小，橢圓齒輪流量計(jì)儀表的泄漏誤差的影響就會(huì)突出，不能再保證足夠的測(cè)量精度。甘肅潛水型電磁流量計(jì)制造商無(wú)線技術(shù)流量計(jì)也正在逐步被用戶(hù)所接受，惡劣環(huán)境中的流體測(cè)量對(duì)無(wú)線技術(shù)來(lái)說(shuō)是一個(gè)很好的應(yīng)用空間。</p><div
