F-550

Acrylic Flow Meter

Blue-White’s F-550 panel-mount-style flow meter has a solid, one-piece machined acrylic body that is annealed for added strength and durability. The F-550 has a clear, glass-like finish and features a white reflective background at the rear of the meter body. This background contrasts with the permanently imprinted scale for an easy meter reading. The available flow range is 0.025 to 20 GPM, and the maximum working pressure is 250psig.
