適用范圍***，進(jìn)行工業(yè)爐窯熱平衡測(cè)試，對(duì)于掌握工業(yè)爐窯的熱能利用情況，提高產(chǎn)品質(zhì)量，為企業(yè)節(jié)能降耗，降低成本，其經(jīng)濟(jì)效益無(wú)疑是巨大的。在實(shí)際測(cè)試的過(guò)程中，渦輪流量計(jì)因其精度高，測(cè)量范圍寬，耐壓高，且有數(shù)字信號(hào)輸出，在工業(yè)鍋爐熱平衡測(cè)試中得到首先選用。

旋渦流量計(jì)是速度式流量計(jì)中的主要種類,當(dāng)被測(cè)流體流過(guò)渦輪流量計(jì)傳感器時(shí)，在流體的作用下，葉輪受力旋轉(zhuǎn)，其轉(zhuǎn)速與管道平均流速成正比，同時(shí)，葉片周期性地切割電磁鐵產(chǎn)生的磁力線，改變線圈的磁通量，根據(jù)電磁感應(yīng)原理，在線圈內(nèi)將感應(yīng)出脈動(dòng)的電勢(shì)信號(hào)，即電脈沖信號(hào)，此電脈動(dòng)信號(hào)的頻率與被測(cè)流體的流量成正比。 </p> <p> 各種流量計(jì)中渦輪流量計(jì)、容積式流量計(jì)和科氏質(zhì)量流量計(jì)是三類重復(fù)性、精確度比較好的產(chǎn)品，而渦輪流量計(jì)又具有自己的特點(diǎn)，如結(jié)構(gòu)簡(jiǎn)單、加工零部件少、重量輕、維修方便、流通能力大（同樣口徑可通過(guò)的流量大）和可適應(yīng)高參數(shù)（高溫、高壓和低溫）等。至今，這類流量計(jì)產(chǎn)品可達(dá)技術(shù)參數(shù)：口徑4-750mm，壓力達(dá)250MPa，溫度為-240-700℃，像這樣的技術(shù)參數(shù)其他兩類流量計(jì)則是難以達(dá)到的。
