廣東廣州液體渦輪流量計一、概述 LWGY系列液體渦輪流量計是吸取了國內外流量儀表先進技術經過優化設計，具有結構簡單、輕巧、精度高、復現性好、反應靈敏，安裝維護使用方便等特點的新一代渦輪流量計，廣泛用于測量封閉管道中與不銹鋼1Cr18Ni9Ti、2Cr13及剛玉Al2O3、硬質合金不起腐蝕作用，且無纖維、顆粒等雜質，工作溫度下運動粘度小于5×10-6m2/s的液體，對于運動粘度大于5×10-6m2/s的液體，可對流量計進行實液標定后使用。若與具有特殊功能的顯示儀表配套，還可以進行定量控制、超量報警等，是流量計量和節能的理想儀表。 該類渦輪流量產品本身價格低廉，集成度高，體積小巧，特別適用于與二次顯示儀、PLC、DCS等計算機控制系統配合使用。廣州顯示流量計，廣州顯示流量計價格

 二、工作原理 流體流經傳感器殼體，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動力矩，克服摩擦力矩和流體阻力之后葉片旋轉，在力矩平衡后轉速穩定，在一定的條件下，轉速與流速成正比，由于葉片有導磁性，它處于信號檢測器（由*磁鋼和線圈組成）的磁場中，旋轉的葉片切割磁力線，周期性的改變著線圈的磁通量，從而使線圈兩端感應出電脈沖信號，此信號經過放大器的放大整形，形成有一定幅度的連續的矩形脈沖波，可遠傳至顯示儀表，顯示出流體的瞬時流量或總量。在一定的流量范圍內，脈沖頻率f與流經傳感器的流體的瞬時流量Q成正比，流量方程為： Q=3600×f/k 式中： f —— 脈沖頻率[Hz] k —— 傳感器的儀表系數[1/m3]，由校驗單給出。若以[1/L]為單位 Q —— 流體的瞬時流量（工作狀態下）[m3/h] 3600 —— 換算系數 每臺傳感器的儀表系數由制造廠填寫在檢定證書中，k值設入配套的顯示儀表中，便可顯示出瞬時流量和累積總量。
 
三、產品特點 1.高精度，一般可達±1%R、±0.5%R，高精度型可達±0.25%R； 2.重復性好，短期重復性可達0.05%~0.2%,正是由于具有良好的重復性，如經常校準或在線校準可得到高的精度，在貿易結算中是優先選用的流量計； 3.輸出脈沖頻率信號，適于總量計量及與計算機連接，無零點漂移，抗干擾能力強； 4.可獲得很高的頻率信號（3-4kHz），信號分辨力強； 5.范圍度寬，中大口徑可達1:20，小口徑為1:10； 6.結構緊湊輕巧，安裝維護方便，流通能力大； 7.適用高壓測量，儀表表體上不必開孔，易制成高壓型儀表； 8.型傳感器類型多，可根據用戶特殊需要設計為各類型傳感器，例如低溫型、雙向型、井下型、混砂型等； 9.可制成插入型，適用于大口徑測量，壓力損失小，價格低，可不斷流取出，安裝維護方便。
