The FPR300 Series comprises
versatile impeller flowmeters in ³⁄₈ to
1" nominal pipe size that employ
jewel bearings for very low
minimum flows. The 6 to 24 Vdc
pulse output of these meters is
compatible with many different
types of control, including a full
range of OMEGA
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.
