渦輪流量計(jì)廣泛應(yīng)用于以下一些測(cè)量對(duì)象：石油、有機(jī)液體、無機(jī)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(yùn)及集輸站，大型原油輸送管線的首末站都大量采用它進(jìn)行貿(mào)易結(jié)算。在歐洲和美國渦輪流量計(jì)是*次于孔板流量計(jì)的天然氣計(jì)量儀表，樂山渦輪流量計(jì)銷售，*荷蘭在天然氣管線上就采用了2600多臺(tái)各種尺寸，壓力從0.8MPa到6.5MPa的氣體渦輪流量計(jì)，他們已成為優(yōu)良的天然氣流量計(jì)。 </p> <p> 盡管渦輪流量計(jì)的優(yōu)良計(jì)量特性受到人們的青睞，樂山渦輪流量計(jì)銷售，樂山渦輪流量計(jì)銷售，可是給人的印象是由活動(dòng)部件，使用期短，在選用時(shí)不免躊躇，經(jīng)過人們的不懈努力，應(yīng)該說情況大有改觀。 </p> <p> 渦輪流量計(jì)作為**通用的流量計(jì)，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。樂山渦輪流量計(jì)銷售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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(dòng)力矩，克服摩擦力矩和流體阻力之后葉片旋轉(zhuǎn)，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(hào)檢測(cè)器（由長久磁鋼和線圈組成）的磁場(chǎng)中，旋轉(zhuǎn)的葉片切割磁力線，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(hào)，此信號(hào)經(jīng)過放大器的放大整形，形成有一定幅度的連續(xù)的矩形脈沖波，可遠(yuǎn)傳至顯示儀表，顯示出流體的瞬時(shí)流量和累計(jì)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(shí)流量Q成正比，流量方程為：Q=3600×f/k 樂山渦輪流量計(jì)銷售</p><div

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(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。 </p><p> 智能氣體 </p> <p> 智能氣體渦輪流量計(jì) </p> <p> 是吸取了國內(nèi)外流量儀表先進(jìn)技術(shù)經(jīng)過優(yōu)化設(shè)計(jì)，綜合了氣體力學(xué)、流體力學(xué)、電磁學(xué)等理論而自行研制開發(fā)的新一代高精度、高可靠性的氣體精密計(jì)量儀表，具有出色的低壓和高壓計(jì)量性能，多種信號(hào)輸出方式以及對(duì)流體擾動(dòng)的低敏感性，***適用于天然氣、煤制氣、液化氣、輕烴氣等氣體的計(jì)量。 </p> <p> 該類渦輪流量產(chǎn)品本身不具備現(xiàn)場(chǎng)顯示功能，*將流量信號(hào)以脈沖信號(hào)的方式遠(yuǎn)傳輸出。儀表價(jià)格低廉，集成度高，體積小巧，特別適用于與二次顯示儀、PLC、DCS等計(jì)算機(jī)控制系統(tǒng)配合使用。該類渦輪流量計(jì)均為防爆產(chǎn)品，防爆等級(jí)為：ExdIIBT6。

</p> <p> 一體化渦輪流量計(jì)，采用先進(jìn)的**功耗單片微機(jī)技術(shù)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，采用雙排液晶現(xiàn)場(chǎng)顯示，具有機(jī)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(diǎn)。儀表具備儀表系數(shù)三點(diǎn)修正，智能補(bǔ)償儀表系數(shù)非線性，并可進(jìn)行現(xiàn)場(chǎng)修正。高清晰液晶顯示器同時(shí)顯示瞬時(shí)流量（4位有效數(shù)字）及累積流量（8位有效數(shù)字，帶清零功能）。所有有效數(shù)據(jù)掉電后保持10年不丟。該類渦輪流量計(jì)均為防爆產(chǎn)品，防爆等級(jí)為：ExdIIBT6。
