旋渦流量計是速度式流量計中的主要種類,當被測流體流過渦輪流量計傳感器時，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，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)電磁感應原理，在線圈內(nèi)將感應出脈動的電勢信號，即電脈沖信號，此電脈動信號的頻率與被測流體的流量成正比。 </p> <p> 各種流量計中渦輪流量計、容積式流量計和科氏質(zhì)量流量計是三類重復性、精確度比較好的產(chǎn)品，而渦輪流量計又具有自己的特點，如結(jié)構(gòu)簡單、加工零部件少、重量輕、維修方便、流通能力大（同樣口徑可通過的流量大）和可適應高參數(shù)（高溫、高壓和低溫）等。至今，這類流量計產(chǎn)品可達技術參數(shù)：口徑4-750mm，壓力達250MPa，溫度為-240-700℃，像這樣的技術參數(shù)其他兩類流量計則是難以達到的。 </p><p> 智能液體渦輪流量計是采用先進的**功耗單片微機技術研制的渦輪流量傳感器與顯示積算一體化的新型智能儀表，具有機構(gòu)緊湊、讀數(shù)直觀清晰、可靠性高、不受外界電源干擾、抗雷擊、成本低等明顯優(yōu)點。 </p> <p> 采用渦輪進行測量的流量計。它先將流速轉(zhuǎn)換為渦輪的轉(zhuǎn)速，再將轉(zhuǎn)速轉(zhuǎn)換成與流量成正比的電信號。這種流量計用于檢測瞬時流量和總的積算流量，其輸出信號為頻率，易于數(shù)字化。圖中感應線圈和長久磁鐵一起固定在殼體上。當鐵磁性渦輪葉片經(jīng)過磁鐵時，磁路的磁阻發(fā)生變化，從而產(chǎn)生感應信號。信號經(jīng)放大器放大和整形，送到計數(shù)器或頻率計，顯示總的積算流量。同時將脈沖頻率經(jīng)過頻率－電壓轉(zhuǎn)換以指示瞬時流量。葉輪的轉(zhuǎn)速正比于流量，葉輪的轉(zhuǎn)數(shù)正比于流過的總量。渦輪流量計的輸出是頻率調(diào)制式信號，不*提高了檢測電路的抗干擾性，而且簡化了流量檢測系統(tǒng)。它的量程比可達10:1，精度在±0.2%以內(nèi)。慣性小而且尺寸小的渦輪流量計的時間常數(shù)可達0.01秒。

渦輪流量計廣泛應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。 </p> <p> 盡管渦輪流量計的優(yōu)良計量特性受到人們的青睞，可是給人的印象是由活動部件，使用期短，在選用時不免躊躇，經(jīng)過人們的不懈努力，應該說情況大有改觀。 </p> <p> 渦輪流量計作為**通用的流量計，其產(chǎn)品已發(fā)展為多品種、全系列、多規(guī)格批量生產(chǎn)的規(guī)模。自貢渦輪流量計銷售</p><p
