流體流經(jīng)傳感器殼體，由于葉輪的葉片與流向有一定的角度，流體的沖力使葉片具有轉(zhuǎn)動力矩，克服摩擦力矩和流體阻力之后葉片旋轉(zhuǎn)，德陽渦輪流量計，在力矩平衡后轉(zhuǎn)速穩(wěn)定，在一定的條件下，轉(zhuǎn)速與流速成正比，由于葉片有導(dǎo)磁性，它處于信號檢測器（由長久磁鋼和線圈組成）的磁場中，旋轉(zhuǎn)的葉片切割磁力線，德陽渦輪流量計，周期性的改變著線圈的磁通量，從而使線圈兩端感應(yīng)出電 </p> <p> 脈沖信號，此信號經(jīng)過放大器的放大整形，德陽渦輪流量計，形成有一定幅度的連續(xù)的矩形脈沖波，可遠傳至顯示儀表，顯示出流體的瞬時流量和累計量。在一定的流量范圍內(nèi)，脈沖頻率f與流經(jīng)傳感器的流體的瞬時流量Q成正比，流量方程為：Q=3600×f/k 德陽渦輪流量計</p><div style="width:100%;text-align:

渦輪流量計廣泛應(yīng)用于以下一些測量對象：石油、有機液體、無機液、液化氣、天然氣、煤氣和低溫流體等。在國外液化石油氣、成品油和輕質(zhì)原油等的轉(zhuǎn)運及集輸站，大型原油輸送管線的首末站都大量采用它進行貿(mào)易結(jié)算。在歐洲和美國渦輪流量計是*次于孔板流量計的天然氣計量儀表，*荷蘭在天然氣管線上就采用了2600多臺各種尺寸，壓力從0.8MPa到6.5MPa的氣體渦輪流量計，他們已成為優(yōu)良的天然氣流量計。
