Cole-Parmer輪子直讀式耐用型PFA相關流量計
耐用框架的*組合以及用化學方法插入的觸濕材料|剛性鋁制框架具有PFA覆層可抗環境腐蝕|適用于超純水或高腐蝕性溶劑的理想選擇。
此類流量計適合用于蝕刻液和高純度水（例如，半導體行業中使用的水）。每個流量計都分別在質譜儀漏氣檢測器上進行了測試，經認證已達到 1x10–7 sccs 氦漏氣率級別或更高。選擇帶閥門的流量計監測和控制流量，或者選擇不帶閥門的流量計，只監測流量。|聚碳酸酯正面防護罩可以將讀數放大 16%，方便在更遠的距離讀數。75 mm 流量計的額定流速為 5,000 ml/min 或以下；125 mm 流量計的額定流速為 13 L/min 及以上。所有型號均附帶水關聯圖表。

什么是轉子流量計?
在一根由下向上擴大的垂直錐管中 , 圓形橫截面的浮子的重力是由液體動力承受的 , 浮子可以在錐管內自由地上升和下降。在流速和浮力作用下上下運動，與浮子重量平衡后，通過磁耦合傳到與刻度盤指示流量。一般分為玻璃和金屬轉子流量計。金屬轉子流量計是工業上常用的，對于小管徑腐蝕性介質通常用玻璃材質，由于玻璃材質的本身易碎性，關鍵的控制點也有用全鈦材等貴重金屬為材質的轉子流量計。
轉子流量計是基于浮子位置測量的一種變面積流量儀表.采用全金屬結構,Modular概念設計,其壓損小,量程比大(10:1),安裝維護方便,可廣泛用于復雜,惡劣環境及各種介質條件的流量測量與過程控制中。
