Polysulfone Flow Meters are designed with chemical and heat resistant one-piece injection-molded polysulfone. Built compact for tight installation spaces, the tough meter body resists high temperatures and pressures. In- line or panel mount configurations are available. Units feature Quik Loc (half union) connectors. that couple the meter to the pipe connectors at each end of the flow meter. For panel mounting, simply drill two holes in your panel, insert the meter fittings through the holes and secure with lock nuts. Rotate for easy reading.
