The carefully engineered design and top-quality construction materials of Blue-White’s Metal-Free Flowmeters makes them well-suited to applications where no metals can be allowed to enter the fluid path, such as ultrapure, DI water and highly corrosive applications. The float, constructed of PTFE, is guided by precisely engineered polysulfone ridges, molded into the meter body. Adapters (polysulfone, PVC or PVDF), O-ring seals (FKM; EP is optional) and Socket Fusion polypropylene or PVDF 63-mm fittings are also offered. http://www.blue-white.com, sales@blue-white.com
