（2）基于金氏定律，直接測量質(zhì)量流量。測量值不受壓力和溫度影響。 </p> <p> （3）響應(yīng)迅速。 </p> <p> （4）量程范圍大，管道式安裝小可以測量8.8mm管道的流量，比較大可以測到30’’ </p> <p> （5）插入式類型的流量計，一支流量計可以用于測量多種管徑。 </p> <p> 缺點: </p> <p> （1）精度不及其他類型流量計，一般為3％。 </p> <p> （2）適用范圍窄，只能用于測量干燥的非性的氣體，如壓縮空氣、氮氣、氬氣及其他中性氣體。江蘇金屬轉(zhuǎn)子流量計電磁流量計測量通道是段光滑直管,不會阻塞,適用于測量含固體顆粒的液固二相流體,如紙漿、泥漿、污水等;</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

這一類孔板是將孔板與測量管做成一體，一般用于小管徑（DN≤50mm），所以又稱小管徑孔板。 </p> <p> 特點： </p> <p> （1）、結(jié)構(gòu)緊湊，牢固耐用，工作可靠。 </p> <p> （2）、可以測小流量，現(xiàn)場安裝方便。 </p> <p> （3）、要求配制一段直管段（前5D、后2D需精密加工）。 </p> <p> 使用條件： </p> <p> （1）、公稱通徑：15-50mm </p> <p> （2）、公稱壓力：≤6.3MPa </p> <p> （3）、精確度（不確定度）：2.5% </p> <p> 2、限流孔板 </p> <p> 用于流體輸送過程的降壓、限流。利用節(jié)流件的壓力損失的特點，來達到降壓、限流的目的。 </p> <p> 特點：結(jié)構(gòu)簡單、耐用、工作可靠。 </p> <p> 不需要測量差壓。 </p><p> 質(zhì)量流量計 </p> <p> 由于流體的容積受溫度、壓力等參數(shù)的影響，用容積流量表示流量大小時需給出介質(zhì)的參數(shù)。在介質(zhì)參數(shù)不斷變化的情況下，往往難以達到這一要求，而造成儀表顯示值失真。因此，質(zhì)量流量計就得到的應(yīng)用和重視。質(zhì)量流量計分直接式和間接式兩種。直接式質(zhì)量流量計利用與質(zhì)量流量直接有關(guān)的原理進行測量，目前常用的有量熱式、角動量式、振動陀螺式、馬格努斯效應(yīng)式和科里奧利力式等質(zhì)量流量計。間接式質(zhì)量流量計是用密度計與容積流量直接相乘求得質(zhì)量流量的。渦輪流量計工作原理：在一定的流量范圍內(nèi)，渦輪的轉(zhuǎn)速與流體的流速成正比。</p><div

style="text-indent:25px">熱電偶安裝時應(yīng)放置在盡可能靠近所要測的溫度控制點。為防止熱量沿熱電偶傳走或防止保護管影響被測溫度，熱電偶應(yīng)浸入所測流體之中，深度至少為直徑的10倍。當測量固體溫度時，熱電偶應(yīng)當頂著該材料或與該材料緊密接觸。為了使導熱誤差減至小，應(yīng)減小接點附近的溫度梯度。當用熱電偶測量管道中的氣體溫度時，如果管壁溫度明顯地較高或較低，則熱電偶將對之輻射或吸收熱量，從而顯著改變被測溫度。這時，可以用一輻射屏蔽罩來使其溫度接近氣體溫度，采用所謂的屏罩式熱電偶。選擇測溫點時應(yīng)具有性，例如測量管道中流體溫度時，熱電偶的測量端應(yīng)處于管道中流速比較大處。一般來說，熱電偶的保護套管末端應(yīng)越過流速中心線。浙江熱式氣體質(zhì)量流量計</p><p
