This paddlewheel flow meter measures flow from 0.07 to 5 GPM at ±1% accuracy. It has a 3/8" (9.5 mm) connection rated to 150 psi (10.34 bar). It suits low-flow liquid measurement and water treatment systems.
This paddlewheel flow meter measures flow from 0.07 to 5 GPM at ±1% accuracy. It has a 3/8" (9.5 mm) connection rated to 150 psi (10.34 bar). It suits low-flow liquid measurement and water treatment systems.
The FPR300 Series comprises versatile impeller flowmeters in 3/8 to 1" (9.5 to 25.4 mm) nominal pipe size that employ jewel bearings for very low minimum flows. The 6 to 24 V DC pulse output of these meters is compatible with many different types of control, including a full range of OMEGA rate displays and controls. The FPR300 Series body material is polypropylene, with transparent acrylic covers for visual flow indication.
Polypropylene covers are available as an option. The FPR310 Series has TFE housing, TFE cover (not visual), PVDF rotor, and a ceramic shaft.
