靶式流量計(jì)正確選型才能保證靶式流量計(jì)更好的使用。選用什么種類的靶式流量計(jì)應(yīng)根據(jù)被測(cè)流體介質(zhì)的物理性質(zhì)和化學(xué)性質(zhì)來(lái)決定?使靶式流量計(jì)的通徑、流量范圍、和輸出方式等都能適應(yīng)被測(cè)流體的性質(zhì)和流量測(cè)量的要求。 </p> <p> 1、精密功能檢查; </p> <p> 精度等級(jí)和功能根據(jù)測(cè)量要求和使用場(chǎng)合選擇儀表精度等級(jí)，做到經(jīng)濟(jì)合算。比如用于貿(mào)易結(jié)算、產(chǎn)品交接和能源計(jì)量的場(chǎng)合，應(yīng)該選擇精度等級(jí)高些，如1.0級(jí)、0.5級(jí)，或者更高等級(jí); 用于過(guò)程控制的場(chǎng)合，根據(jù)控制要求選擇不同精度等級(jí);有些**是檢測(cè)一下過(guò)程流量，無(wú)需做精確控制和計(jì)量的場(chǎng)合，可以選擇精度等級(jí)稍低的，如1.5級(jí)、2.5級(jí)，甚至 4.0級(jí)，這時(shí)可以選用價(jià)格低廉的插入式靶式流量計(jì)。 </p> <p> 2、可測(cè)量的介質(zhì); </p> <p> 測(cè)量介質(zhì)流速、儀表量程與口徑測(cè)量一般的介質(zhì)時(shí)，靶式流量計(jì)的滿度流量可以在測(cè)量介質(zhì)流速0.1-12m/s范圍內(nèi) 選用，范圍比較寬。選擇儀表規(guī)格(口徑)不一定與工藝管道相同，應(yīng)視測(cè)量流量范圍是否在流速范圍內(nèi)確定，即當(dāng)管道流速偏低，不能滿足流量?jī)x表要求時(shí)或者在此流速下測(cè)量準(zhǔn) 確度不能保證時(shí)，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測(cè)量結(jié)果。便攜式超聲波流量計(jì)制造商透明錐形管4用得普遍是由硼硅玻璃制成，習(xí)慣簡(jiǎn)稱玻璃管浮子流量計(jì)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

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(wàn)用表測(cè)量電壓，不足之處是在安裝時(shí)需要一定直管段，且普通型對(duì)于振動(dòng)和高溫沒(méi)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(guò)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(guò)測(cè)定殼體和轉(zhuǎn)子之間形成的計(jì)量容積來(lái)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，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，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。 </p><p> 傳播速度差法超聲流量計(jì)測(cè)量精度已優(yōu)于，有的多聲道超聲流量計(jì)的精度已高達(dá)士。但由于早期的超聲流量計(jì)自身一般不帶標(biāo)準(zhǔn)管道而工業(yè)上所用管路又十分復(fù)雜，使得超聲流量計(jì)的測(cè)量精度大打折扣;另外，由于工業(yè)現(xiàn)場(chǎng)特別是管路周圍環(huán)境的多樣性和復(fù)雜性，降低了超聲流量計(jì)的可靠性和穩(wěn)定性。因此，如何根據(jù)特定的環(huán)境安裝調(diào)試超聲流量計(jì)，就成了超聲流量測(cè)量領(lǐng)域的一個(gè)重要課題。符合規(guī)范的正確安裝，可以更好地體現(xiàn)超聲流量計(jì)的精度、可靠性和穩(wěn)定性方面的優(yōu)勢(shì)，降低儀表的日常維護(hù)工作。以前盛行的外夾裝式超聲流量計(jì)使用方便靈活，然而現(xiàn)場(chǎng)應(yīng)用的實(shí)際側(cè)量精度，常因工作琉忽，換能器安裝距離及流通面積等測(cè)量的誤差而造成梢度下降。不正確的安裝甚至?xí)沟脙x表完全不能工作;因此，安裝換能器對(duì)于測(cè)量是非常重要環(huán)節(jié):國(guó)外競(jìng)相開(kāi)發(fā)出經(jīng)實(shí)流核準(zhǔn)的高精度帶測(cè)量管段的中小口徑超聲流量計(jì)，且用雙聲道或多聲道以改善單聲道側(cè)量平均流速的不確定影響量，降低了迎流流速分布影響的敏感度，減少了前后置直管段長(zhǎng)度的影響，消除了現(xiàn)場(chǎng)安裝換能器位置的影響，使測(cè)量精度提高。渦輪流量計(jì)是速度式流量計(jì)中的主要種類，采用多葉片的轉(zhuǎn)子感受流體平均流速，從而推導(dǎo)出流量或總量的儀表。</p><div

智能型電磁流量計(jì)傳感器在工藝管道上的安裝：1.智能型電磁流量計(jì)測(cè)堵管在任何時(shí)刻必須完全注滿介質(zhì)，不能在不滿管或空管的情況下正常工作。在介質(zhì)不滿管時(shí)，可采用抬高流量計(jì)后端出水管高度的方法使介質(zhì)滿管，避免不滿管及氣體附著在電極上。2.管道內(nèi)有真空會(huì)損壞流量計(jì)的內(nèi)襯，需特別注意。3.流動(dòng)的正方向應(yīng)與流量計(jì)上箭頭所指的正方向一致。4.智能型電磁流量計(jì)即可在直管道上安裝，也可以在水平或傾斜管道上安裝，但要求二電極的中心連線處于水平狀態(tài)。5.對(duì)于液、固兩相流體，zui好采用垂直安裝，使被測(cè)介質(zhì)自上而xialiu動(dòng)，可使流量計(jì)襯里磨損均勻，延長(zhǎng)使用壽命。6.流量計(jì)在管道法蘭附近確保有足夠的空間，以便安裝和維護(hù)。7.若測(cè)量管道有振動(dòng)，在流量計(jì)的兩側(cè)應(yīng)有固定的支座。8.測(cè)量介質(zhì)為重污染液體的，在旁路管道安裝流量計(jì)本體，不中斷工藝運(yùn)行，即可排空與清流。9.安裝聚四氟乙烯內(nèi)襯的流量計(jì)時(shí)，連接法蘭的螺栓應(yīng)注意均勻擰緊，否則容易壓壞聚四氟乙烯內(nèi)襯，zui好用力矩扳手。將浮子位移量轉(zhuǎn)換成電流或氣壓模擬量信號(hào)輸出，分別成為電遠(yuǎn)傳浮子流量計(jì)和氣遠(yuǎn)傳浮子流量計(jì)。新疆插入式渦街流量計(jì)</p><p
