超聲波krom流量計：超聲波流量計是基于超聲波在流動介質(zhì)中傳播的速度等于被測介質(zhì)的平均流速和聲波本身速度的幾何和的原理而設(shè)計的。它也是由測流速來反映流量大小的。超聲波流量計按測量原理可分為時差式和多普勒式。應(yīng)用：傳播時間法應(yīng)用于清潔、單相液體和氣體。典型應(yīng)用有工廠排放液、怪液、液化天然氣等;氣體應(yīng)用方面在高壓天然氣領(lǐng)域已有使用良好的經(jīng)驗;多普勒法適用于異相含量不太高的雙相流體，如未處理污水、工廠排放液、臟流程液，通常不適用于非常清潔的液體。

渦街流量計是在流體中安放一根非流線型游渦發(fā)生體，流體在發(fā)生體兩側(cè)交替地分離釋放出兩串規(guī)則地交錯排列的游渦的儀表。當通過流截面一定時，流速與導(dǎo)容積流量成正比。因此，測量振蕩頻率即可測得流量。應(yīng)用：渦街流量計發(fā)展迅速，目前已成為通用的一類流量計。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(yīng)用于石油、工業(yè)、冶金、電力等各個領(lǐng)域，在國民經(jīng)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(yīng)用,通過規(guī)范設(shè)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。 </p> <p> <br /> </p> <p> <br /> </p><p> 燃氣流量計原理：燃氣流量計采用熱擴散原理，熱擴散技術(shù)是一種在苛刻條件下性能優(yōu)良、可靠性高的技術(shù)。其典型傳感元件包括兩個熱電阻（鉑RTD），一個是速度傳感器，一個是自動補償氣體溫度變化的溫度傳感器。當兩個RTD被置于介質(zhì)中時，其中速度傳感器被加熱到環(huán)境溫度以上的一個恒定的溫度，另一個溫度傳感器用于感應(yīng)介質(zhì)溫度。流經(jīng)速度傳感器的燃氣流量是通過傳感元件的熱傳遞量來計算的。氣體流速增加，介質(zhì)帶走的熱量增多。使傳感器溫度隨之降低。為了保持溫度的恒定，則必須增加通過傳感器的工作電流，此增加的部分電流大小與介質(zhì)的流速成正比。

krom//schroeder霍科德流量計應(yīng)用領(lǐng)域工業(yè)生產(chǎn)：流量儀表是過程自動化儀表與裝置中的大類儀表之一，是發(fā)展工農(nóng)業(yè)生產(chǎn)，節(jié)約能源，改進產(chǎn)品質(zhì)量，提高經(jīng)濟效益和管理水平的重要工具在國民經(jīng)濟中占有重要的地位。能源計量：能源分為一次能源（煤炭、原油、煤層氣、石油氣和天然氣）、二次能源（電力、焦炭、人工燃氣、成品油、液化石油氣、蒸汽）及載能工質(zhì)（壓縮空氣、氧、氮、氫、水）等。能源計量是科學管理能源，實現(xiàn)節(jié)能降耗，提高經(jīng)濟效益的重要手段。流量儀表是能源計量儀表的重要組成部分，水、人工燃氣、天然氣、蒸汽和油品這些常用的能源都使用著數(shù)量極其龐大的流量計，它們是能源管理和經(jīng)濟核算不可缺少的工具。

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(jié)構(gòu)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(shè)于殼體內(nèi)，芯軸與殼體之間還設(shè)置有一定的密封結(jié)構(gòu)，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(jīng)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(jié)構(gòu)，因此在使用一段時間后該軸承的轉(zhuǎn)動靈活度就會下降，使得芯軸和燃氣輪的轉(zhuǎn)速降低，相應(yīng)的導(dǎo)致殼體內(nèi)部氣壓增高，一旦殼體內(nèi)部氣壓增高到一定程度，就會導(dǎo)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。
