渦輪krom流量計：渦輪流量計是速度式流量計中的主要種類，它采用多葉片的轉子(渦輪)感受流體平均流速，從而且推導出流量或總量的儀表。一般它由傳感器和顯示儀器兩部分組成，也可做成整體式。應用：渦輪流量計在測量石油、有機液體、無機液、液化氣、天然氣和低溫流體獲得普遍應用。天然氣流量計是過程自動化儀表與裝置中的重要的儀表，作為能源計量器具的重要組成部分,被普遍應用于石油、工業(yè)、冶金、電力等各個領域，在國民經濟中占有重要的地位.文章介紹了常用流量儀表在石油化工行業(yè)中的的選型及應用,通過規(guī)范設計、合理選型、正確的安裝和維護，讓流量儀表在天然氣行業(yè)中發(fā)揮更大的作用。在此虎博小編就帶大家來了解一下燃氣流量計的工作原理和特點吧。

應用：差壓式流量計應用范圍特別普遍,在封閉管道的流量測量中各種對象都有應用，如流體方面：單相、混相、潔凈、臟污、粘性流等;工作方面：常壓、高壓、真空、常溫、高溫、低溫等;管徑方面：從幾毫米到幾米;流動方面：亞音速、音速、脈動流等。它在各工業(yè)部門的用量約占krom流量計全部用量的1/4～1/3。浮子流量計又稱轉子流量計，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式由液體動力承受的，從而使浮子可以在錐管內自由地上升和下降。應用：浮子流量計是僅次于差壓式流量計應用范圍**寬廣的一類流量計，特別在小、微流量方面有舉足輕重的作用。 </p> <p> <br /> </p> <p> <br /> </p><p> 燃氣流量計原理：熱式燃氣流量計主要利用的是熱擴散原理。熱擴散原理的物理條件主要由兩個對溫度敏感的熱電阻構成，其中一個用作速度傳感器，另一個用作溫度傳感器以實現(xiàn)對燃氣溫度變化的自動補償功能。當物理條件得以滿足后，熱式燃氣流量計便處于正常工作狀態(tài)下，一旦有燃氣流過，溫度傳感器則進行其溫度的升高或降低來維持燃氣流量的恒定，因此可通過對電路中電流的測量來對燃氣的流速作以判斷。燃氣流速越快，帶走的熱量越多，使得傳感器溫度降低，為保持溫度恒定，電路中電流得以增加;反之，當電路中電流呈減少趨勢時，表明燃氣流速也正處于降低狀態(tài)，流速與電流呈現(xiàn)正比關系。

在燃氣輸配行業(yè)，燃氣氣體流量計是使用相當普遍的高精度計量儀器。目前在用的燃氣氣體流量計結構上主要包括殼體、芯軸和燃氣輪，所述芯軸通過軸承與殼體連接，燃氣輪安裝在芯軸上并設于殼體內，芯軸與殼體之間還設置有一定的密封結構，以防氣體外泄。發(fā)明人通過研究分析發(fā)現(xiàn)，上述的燃氣氣體流量計存在一個長期以來一直被忽視的缺點：由于經過該燃氣流量計的燃氣（如天然氣）中往往含有一定量的粉塵，而燃氣氣體流量計中沒有能夠有效阻斷這些粉塵侵入所述軸承的結構，因此在使用一段時間后該軸承的轉動靈活度就會下降，使得芯軸和燃氣輪的轉速降低，相應的導致殼體內部氣壓增高，一旦殼體內部氣壓增高到一定程度，就會導致殼體中的受計量氣體從燃氣輪與殼體之間的配合間隙穿過，從而影響燃氣流量計的計量精度。
