1、精密功能檢查; </p> <p> 精度等級和功能根據(jù)測量要求和使用場合選擇儀表精度等級，做到經(jīng)濟合算。比如用于貿(mào)易結(jié)算、產(chǎn)品交接和能源計量的場合，應該選擇精度等級高些，如1.0級、0.5級，或者更高等級; 用于過程控制的場合，根據(jù)控制要求選擇不同精度等級;有些**是檢測一下過程流量，無需做精確控制和計量的場合，可以選擇精度等級稍低的，如1.5級、2.5級，甚至 4.0級，這時可以選用價格低廉的插入式靶式流量計。 </p> <p> 2，甘肅插入式渦街流量計制造商、可測量的介質(zhì); </p> <p> 測量介質(zhì)流速、儀表量程與口徑測量一般的介質(zhì)時，靶式流量計的滿度流量可以在測量介質(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，甘肅插入式渦街流量計制造商，應視測量流量范圍是否在流速范圍內(nèi)確定，即當管道流速偏低，甘肅插入式渦街流量計制造商，不能滿足流量儀表要求時或者在此流速下測量準確度不能保證時，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測量結(jié)果。流量計是測量液體、氣體流量必不可少的儀表。甘肅插入式渦街流量計制造商</p><div

感應式電磁流量計在被測流體溫度過高或?qū)﹄姌O有強烈腐蝕作用等情況下，可采用感應式電磁流量計。A、B為匝數(shù)相等的兩個交流激磁繞組，繞組之間是串聯(lián)的，但各自的電流方向相反。當流體靜止時，通過感應線圈C的合成磁通為零，故線圈中沒有感生的交變電動勢。流體流動時感應線圈中就產(chǎn)生交變電動勢，其大小與流速成正比。基于這一原理，還有很多改型方案。例如用一個激磁繞組，而在它的對稱的兩側(cè)各安置一方向相反的感應線圈并串聯(lián)起來流體流動時，磁力線向流動方向移動，使兩邊感應線圈中的產(chǎn)生電動勢不為零，由此可間接表示出流量的大小。電磁流量計的管道內(nèi)沒有其他部件，所以除用于測量導電流體的流量外，還可用于測量各種粘度的不導電液體（其中加入易電離物質(zhì)）的流量。在核能工業(yè)中經(jīng)常使用電磁流量計。 </p><p> 管道式電磁流量計: </p> <p> 1．對直段的要求: </p> <p> 為了改善渦流與流場畸變的影響，流量計安裝的前、后直管段長度有一定要求，否則會影響測量精度（也可安裝整流器，盡量避免在靠近調(diào)節(jié)閥和半開閥門之后安裝）。 </p> <p> 2．對工藝管的要求: </p> <p> 流量計對安裝點的上、下游工藝管有一定的要求，否則影響測量精度。 </p> <p> a．上、下游工藝管的內(nèi)徑與傳感器的內(nèi)徑相同，并應滿足：0.98DN≤D≤1.05DN（式中DN：傳感器內(nèi)徑，D：工藝管內(nèi)徑）; </p> <p> b．工藝管與傳感器必須同心，同軸偏差應不大于0.05DN. </p> <p> 3．旁通管的要求: </p> <p> 為了方便檢修流量計，比較好為流量計安裝旁通管，另外，對重污染流體及流量計需清而流體不能停止的，必須安裝旁通管。 </p> <p> a．方便流量計的檢修; </p> <p> b．對重污染流體必須安裝; </p> <p> c．流體不能停止而流量計需清洗. 一體型儀表將孔板和浮子流量計組裝在短管段上，直接裝到待測管道，安裝方便。</p><div style="width:100%;text-align:

液體流量計的正確使用步驟:在使用壓力傳感器前，對其進行性能測試。將它接上透明的水管，用水柱高坐壓力，用高靈敏度數(shù)字萬用表測量電壓，不足之處是在安裝時需要一定直管段，且普通型對于振動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方面有優(yōu)勢，但價格較貴，一般用于過熱蒸汽的測量。只要能傳播聲音的流體均可以用液體流量計;超聲波流量計可以測量高粘度液體、非導電性液體或氣體的流量，其測量流速的原理是:超聲波在流體中的傳播速度會隨被測流體流速而變化。容積式流量計容積式流量計是通過測定殼體和轉(zhuǎn)子之間形成的計量容積來測量流體的體積流量。根據(jù)轉(zhuǎn)子的結(jié)構(gòu)形式，容積式流量計有腰輪式，刮板式、橢圓齒輪式等。隨著工業(yè)發(fā)展對流量計量要求的不斷提高，液體流量計在工業(yè)測量中的地位已經(jīng)部分地被先進的、高精度的、便利的流量儀表所取代。液體流量計基于法拉第電磁感應原理研制出的一種測量導電液體體積流量的儀表。又稱轉(zhuǎn)子流量計，是變面積式流量計的一種，在一根由下向上擴大的垂直錐管中，圓形橫截面的浮子的重力是由液體動力承受的。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動與浮子重量平衡后。浮子流量計：在由下向上擴大的圓錐形內(nèi)孔的垂直管子中，由管子中浮子的位置來表示流量示值的變面積流量計。寧夏橢圓齒輪流量計</p><p style="text-indent:25px">將浮子位移量轉(zhuǎn)換成電流或氣壓模擬量信號輸出，分別成為電遠傳浮子流量計和氣遠傳浮子流量計。甘肅插入式渦街流量計制造商</p><p> 電磁流量計的結(jié)構(gòu)主要由磁路系統(tǒng)、測量導管、電極、外殼、襯里和轉(zhuǎn)換器等部分組成。 </p> <p> 電極：其作用是引出和被測量成正比的感應電勢信號。電極一般用非導磁的不銹鋼制成，且被要求與襯里齊平，以便流體通過時不受阻礙。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量精度。 </p> <p> 外殼：應用鐵磁材料制成，是分配制度勵磁線圈的外罩，并隔離外磁場的干擾。 </p> <p> 襯里：在測量導管的內(nèi)側(cè)及法蘭密封面上，有一層完整的電絕緣襯里。它直接接觸被測液體，其作用是增加測量導管的耐腐蝕性，防止感應電勢被金屬測量導管管壁短路。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：由液體流動產(chǎn)生的感應電勢信號十分微弱，受各種干擾因素的影響很大，轉(zhuǎn)換器的作用就是將感應電勢信號放大并轉(zhuǎn)換成統(tǒng)一的標準信號并yizhi主要的干擾信號。其任務是把電極檢測到的感應電勢信號Ex經(jīng)放大轉(zhuǎn)換成統(tǒng)一的標準直流信號。甘肅插入式渦街流量計制造商</p><p
