Cole-Parmer轮子直读式耐用型PFA相关流量计
耐用框架的*组合以及用化学方法插入的触湿材料|刚性铝制框架具有PFA覆层可抗环境腐蚀|适用于超纯水或高腐蚀性溶剂的理想选择。
此类流量计适合用于蚀刻液和高纯度水（例如，半导体行业中使用的水）。每个流量计都分别在质谱仪漏气检测器上进行了测试，经认证已达到 1x10–7 sccs 氦漏气率级别或更高。选择带阀门的流量计监测和控制流量，或者选择不带阀门的流量计，只监测流量。|聚碳酸酯正面防护罩可以将读数放大 16%，方便在更远的距离读数。75 mm 流量计的额定流速为 5,000 ml/min 或以下；125 mm 流量计的额定流速为 13 L/min 及以上。所有型号均附带水关联图表。

什么是转子流量计?
在一根由下向上扩大的垂直锥管中 , 圆形横截面的浮子的重力是由液体动力承受的 , 浮子可以在锥管内自由地上升和下降。在流速和浮力作用下上下运动，与浮子重量平衡后，通过磁耦合传到与刻度盘指示流量。一般分为玻璃和金属转子流量计。金属转子流量计是工业上常用的，对于小管径腐蚀性介质通常用玻璃材质，由于玻璃材质的本身易碎性，关键的控制点也有用全钛材等贵重金属为材质的转子流量计。
转子流量计是基于浮子位置测量的一种变面积流量仪表.采用全金属结构,Modular概念设计,其压损小,量程比大(10:1),安装维护方便,可广泛用于复杂,恶劣环境及各种介质条件的流量测量与过程控制中。
