液體流量計(jì)的正確使用步驟:在使用壓力傳感器前，對(duì)其進(jìn)行性能測(cè)試。將它接上透明的水管，用水柱高坐壓力，用高靈敏度數(shù)字萬用表測(cè)量電壓，不足之處是在安裝時(shí)需要一定直管段，橢圓齒輪流量計(jì)分類，且普通型對(duì)于振動(dòng)和高溫沒有很好的解決辦法。渦街有壓電式和電容式，后者在耐溫和耐振動(dòng)方面有優(yōu)勢(shì)，但價(jià)格較貴，一般用于過熱蒸汽的測(cè)量。只要能傳播聲音的流體均可以用液體流量計(jì);超聲波流量計(jì)可以測(cè)量高粘度液體、非導(dǎo)電性液體或氣體的流量，其測(cè)量流速的原理是:超聲波在流體中的傳播速度會(huì)隨被測(cè)流體流速而變化。容積式流量計(jì)容積式流量計(jì)是通過測(cè)定殼體和轉(zhuǎn)子之間形成的計(jì)量容積來測(cè)量流體的體積流量。根據(jù)轉(zhuǎn)子的結(jié)構(gòu)形式，容積式流量計(jì)有腰輪式，刮板式、橢圓齒輪式等。隨著工業(yè)發(fā)展對(duì)流量計(jì)量要求的不斷提高，橢圓齒輪流量計(jì)分類，液體流量計(jì)在工業(yè)測(cè)量中的地位已經(jīng)部分地被先進(jìn)的、高精度的、便利的流量?jī)x表所取代。液體流量計(jì)基于法拉第電磁感應(yīng)原理研制出的一種測(cè)量導(dǎo)電液體體積流量的儀表。又稱轉(zhuǎn)子流量計(jì)，是變面積式流量計(jì)的一種，橢圓齒輪流量計(jì)分類，在一根由下向上擴(kuò)大的垂直錐管中，圓形橫截面的浮子的重力是由液體動(dòng)力承受的。浮子可以在錐管內(nèi)自由地上升和下降。在流速和浮力作用下上下運(yùn)動(dòng)與浮子重量平衡后。金屬管浮子流量計(jì)為現(xiàn)場(chǎng)智能指示型，有下進(jìn)上出、左進(jìn)右出和下進(jìn)側(cè)出三種安裝形式。橢圓齒輪流量計(jì)分類</p><div

電極：其作用是引出和被測(cè)量成正比的感應(yīng)電勢(shì)信號(hào)。電極一般用非導(dǎo)磁的不銹鋼制成，且被要求與襯里齊平，以便流體通過時(shí)不受阻礙。它的安裝位置宜在管道的垂直方向，以防止沉淀物堆積在其上面而影響測(cè)量精度。 </p> <p> 外殼：應(yīng)用鐵磁材料制成，是分配制度勵(lì)磁線圈的外罩，并隔離外磁場(chǎng)的干擾。 </p> <p> 襯里：在測(cè)量導(dǎo)管的內(nèi)側(cè)及法蘭密封面上，有一層完整的電絕緣襯里。它直接接觸被測(cè)液體，其作用是增加測(cè)量導(dǎo)管的耐腐蝕性，防止感應(yīng)電勢(shì)被金屬測(cè)量導(dǎo)管管壁短路。襯里材料多為耐腐蝕、耐高溫、耐磨的聚四氟乙烯塑料、陶瓷等。 </p> <p> 轉(zhuǎn)換器：由液體流動(dòng)產(chǎn)生的感應(yīng)電勢(shì)信號(hào)十分微弱，受各種干擾因素的影響很大，轉(zhuǎn)換器的作用就是將感應(yīng)電勢(shì)信號(hào)放大并轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)信號(hào)并yizhi主要的干擾信號(hào)。其任務(wù)是把電極檢測(cè)到的感應(yīng)電勢(shì)信號(hào)Ex經(jīng)放大轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)直流信號(hào)。渦輪流量計(jì)推薦廠家電磁流量計(jì)、超聲波流量計(jì)、渦街流量計(jì)利用電氣原理工作，從而避免了機(jī)械流量計(jì)工作中需要更換的運(yùn)動(dòng)機(jī)件。</p><div
