The carefully engineered design, and top quality materials of construction of Blue-White’s Metal-Free Flowmeters, makes them well suited to applications where no metals can enter the fluid path, such as UltraPure, DI Water and highly corrosive applications.
The float is guided by precisely engineered Polysulfone ridges, molded into the meter body, floats are constructed of PTFE. This means no metal contaminants in the fluid path. Adapters are constructed of Polysulfone, PVC or PVDF, depending on model ordered, and O-ring seals are FKM (EP is optional).
Optional Socket Fusion, 63mm, fittings are also offered. Socket Fusion fitting materials are Polypropylene or PVDF, depending on model ordered.
