style="text-indent:25px">容積式流量計，又稱定排量流量計，簡稱PD流量計，在流量儀表中是精度較高的一類。它利用機械測量元件把流體連續(xù)不斷地分割成單個已知的體積部分，根據(jù)測量室逐次重復(fù)地充滿和排放該體積部分流體的次數(shù)來測量流體體積總量。容積式流量計按其測量元件分類，可分為橢圓齒輪流量計、刮板流量計、雙轉(zhuǎn)子流量計、旋轉(zhuǎn)活塞流量計、往復(fù)活塞流量計、圓盤流量計、液封轉(zhuǎn)筒式流量計、濕式氣量計及膜式氣量計等。優(yōu)點：（1）計量精度高；（2）安裝管道條件對計量精度沒有影響；（3）可用于高粘度液體的測量；（4）范圍度寬；（5）直讀式儀表無需外部能源可直接獲得累計總量，清晰明了，操作簡便。渦輪流量計訂購流量計在使用過程中，要對現(xiàn)場的環(huán)境進行改善。</p><div

style="text-indent:25px">差壓式流量計的檢測件按其作用原理可分為：節(jié)流裝置、水力阻力式、離心式、動壓頭式、動壓頭增益式及射流式幾大類。檢測件又可按其標準化程度分為二大類：標準的和非標準的。所謂標準檢測件是只要按照標準文件設(shè)計、制造、安裝和使用，無須經(jīng)實流標定即可確定其流量值和估算測量誤差。非標準檢測件是成熟程度較差的，尚未列入國際標準中的檢測件。差壓式流量計是一類應(yīng)用較普遍的流量計，在各類流量儀表中其使用量占居**。由于各種新型流量計的問世，它的使用量百分數(shù)逐漸下降，但目前仍是重要的一類流量計。</p><p style="text-indent:25px">流量計的一般選型可以從這些方面進行考慮，這五個方面為流量計儀表性能方面、流體特性方面、安裝條件方面、環(huán)境條件方面和經(jīng)濟因素方面。五個方面的詳細因素如下：儀表性能方面：準確度、重復(fù)性、線性度、范圍度、流量范圍、信號輸出特性、響應(yīng)時間、壓力損失等；流體特性方面：溫度、壓力、密度、粘度、化學腐蝕、磨蝕性、結(jié)垢、混相、相變、電導(dǎo)率、聲速、導(dǎo)熱系數(shù)、比熱容，等熵指數(shù)；安裝條件方面：管道布置方向，流動方向，檢測件上下游側(cè)直管段長度、管道口徑，維修空間、電源、接地、輔助設(shè)備(過濾器、消氣器)、安裝、等；環(huán)境條件方面：環(huán)境溫度、濕度、電磁干擾、安全性、防爆、管道振動等；經(jīng)濟因素方面：儀表購置費、安裝費、運行費、校驗費、維修費、儀表使用壽命、備品備件等。流量計不能安裝在大型變壓器、電動機、機泵等產(chǎn)生較大磁場的設(shè)備附近。</p><div

style="text-indent:25px">對于渦街流量計來說，測量氣體流量時，若被測氣體含有少量的液體，流量計應(yīng)安裝在管線的較高處。測量液體時，若被測液體中含有少量的氣體，流量計應(yīng)安裝在管線的較低處。測壓孔和測溫孔：需要測壓時,須將測壓孔設(shè)置在流量計下游2~7D的地方。需要測溫時,將溫度傳感器設(shè)置在離測壓點下游的1~2D之間處。管道支撐：盡量將流量計安裝在振動加速度小于20m/s2的地方。當管道振動過強時,應(yīng)對管道安裝加固支撐。封墊片：切不可將密封墊片突出到管道中,否則將導(dǎo)致無法接受的誤差。差壓式流量計在封閉管道的流量測量中各種對象都有應(yīng)用。渦輪流量計訂購</p><p style="text-indent:25px">流量計是用于測量管道或明渠中流體流量的一種儀表。高粘度流量計廠家</p><p style="text-indent:25px">轉(zhuǎn)子流量計工作原理：當測量流體的流量時，被測流體從錐形管下端流入，流體的流動沖擊著轉(zhuǎn)子，并對它產(chǎn)生一個作用力，當流量足夠大時，產(chǎn)生的作用力將轉(zhuǎn)子托起。同時，被測流體流經(jīng)轉(zhuǎn)子與錐形管壁間的環(huán)形斷面，這時作用在轉(zhuǎn)子上的力有三個:流體對轉(zhuǎn)子的動壓力、轉(zhuǎn)子在流體中的浮力和轉(zhuǎn)子自身的重力。流量計垂直安裝時，轉(zhuǎn)子重心與錐管管軸會相重合，作用在轉(zhuǎn)子上的三個力都沿平行于管軸的方向。當這三個力達到平衡時，轉(zhuǎn)子就平穩(wěn)地浮在錐管內(nèi)某一位置上。對于給定的轉(zhuǎn)子流量計，轉(zhuǎn)子大小和形狀己經(jīng)確定，因此它在流體中的浮力和自身重力都是已知是常量，唯有流體對浮子的動壓力是隨來流流速的大小而變化的。因此當來流流速變大或變小時，轉(zhuǎn)子將作向上或向下的移動，相應(yīng)位置的流動截面積也發(fā)生變化，直到流速變成平衡時對應(yīng)的速度，轉(zhuǎn)子就在新的位置上穩(wěn)定。對于一臺給定的轉(zhuǎn)子流量計，轉(zhuǎn)子在錐管中的位置與流體流經(jīng)錐管的流量的大小成一一對應(yīng)關(guān)系。高粘度流量計廠家</p><p
