There are no metals in the fluid path of F-462N Series inline variable-area flowmeters from Blue-White Industries, making these units well-suited for use in many ultrapure applications. Constructed of tough, chemical-resistant polysulfone, they offer better resistance to high temperatures, pressures and a broad base of harsh chemicals. These high-capacity flowmeters utilize precisely engineered ridges molded into the meter body, which guide PTFE floats. Calibration range is 2.0 to 80 gpm (8.0 to 300 L/m) and permanent direct-reading scales are easy to read. Features include polysulfone two-inch (50.8-mm) F/NPT fittings with FKM O-rings and half-union adapter connections. Socket fusion fittings are available. Maximum fluid temperature is 200°F/93°C at zero psi. Maximum working pressure is 150 psi/10.3 bar at 70°F/21°C. An optional splash shield is available.
