Cole-Parmer輪子直讀式耐用型PFA相關(guān)流量計
耐用框架的*組合以及用化學(xué)方法插入的觸濕材料|剛性鋁制框架具有PFA覆層可抗環(huán)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(dǎo)體行業(yè)中使用的水）。每個流量計都分別在質(zhì)譜儀漏氣檢測器上進行了測試，經(jīng)認(rèn)證已達(dá)到 1x10–7 sccs 氦漏氣率級別或更高。選擇帶閥門的流量計監(jiān)測和控制流量，或者選擇不帶閥門的流量計，只監(jiān)測流量。|聚碳酸酯正面防護罩可以將讀數(shù)放大 16%，方便在更遠(yuǎn)的距離讀數(shù)。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(guān)聯(lián)圖表。

什么是轉(zhuǎn)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(nèi)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(zhuǎn)子流量計。金屬轉(zhuǎn)子流量計是工業(yè)上常用的，對于小管徑腐蝕性介質(zhì)通常用玻璃材質(zhì)，由于玻璃材質(zhì)的本身易碎性，關(guān)鍵的控制點也有用全鈦材等貴重金屬為材質(zhì)的轉(zhuǎn)子流量計。
轉(zhuǎn)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(jié)構(gòu),Modular概念設(shè)計,其壓損小,量程比大(10:1),安裝維護方便,可廣泛用于復(fù)雜,惡劣環(huán)境及各種介質(zhì)條件的流量測量與過程控制中。
