按照要求正確安裝后的橢圓齒輪流量計(jì)，使用時(shí)即可保證足夠的精度，通常累計(jì)值的精度可達(dá)0.5級(jí)，是一種較橢圓齒輪流量計(jì)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，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。因此，不同型號(hào)規(guī)格的橢圓齒輪流量計(jì)對(duì)zui小使用流量有一允許值，只有當(dāng)實(shí)際被測(cè)流量大于該下限流量允許值時(shí)，測(cè)量精度才能得到保證。 </p> <p> 其次，使用橢圓齒輪流量計(jì)要注意被測(cè)介質(zhì)的溫度不能過(guò)高，否則不僅會(huì)增加測(cè)量誤差，而且有使齒輪發(fā)生卡死的可能。為此，橢圓齒輪流量計(jì)在儀表所規(guī)定的使用溫度范圍內(nèi)使用。 </p> <p> 長(zhǎng)期使用后的橢圓齒輪流量計(jì)，其內(nèi)部的齒輪會(huì)被腐蝕和磨損，從而影響測(cè)量精度。因此，要經(jīng)常注意觀察，并定期拆下進(jìn)行檢查，若條件允許要定期進(jìn)行標(biāo)定。插入式渦旋流量計(jì)廠家分流型相對(duì)于全流型只有部分被測(cè)流體流過(guò)浮子等流量檢測(cè)部分。</p><div

特點(diǎn)：流量測(cè)量與流體的流動(dòng)狀態(tài)無(wú)關(guān)，這是因?yàn)闄E圓齒輪流量計(jì)是依靠被測(cè)介質(zhì)的壓頭推動(dòng)橢圓齒輪旋轉(zhuǎn)而進(jìn)行計(jì)量的。粘度愈大的介質(zhì)，從齒輪和計(jì)量空間隙中泄漏出去的泄漏量愈小，因此核測(cè)介質(zhì)的粘皮愈大，泄漏誤差愈小，對(duì)測(cè)量愈有利。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(固體顆粒會(huì)將齒輪卡死，以致無(wú)法測(cè)量流量)。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。 </p> <p> 安裝：橢圓齒輪流量計(jì)在安裝前應(yīng)清潔管道.若液體內(nèi)含有固體顆粒，則必須在管道上游加裝過(guò)濾器;若含氣體應(yīng)安裝排氣裝置。HI-TOUCH M系列橢圓齒輪流量計(jì)橢圓齒輪流量計(jì)對(duì)前后直管段沒(méi)有一定的要求。它可以水平或垂直安裝。安裝時(shí)，應(yīng)使流量計(jì)的橢圓齒輪轉(zhuǎn)動(dòng)軸與地面平行。 </p><p
