GENERAL INFORMATION
These versatile impeller flowmeters are available in 3/8",
1/2", 3/4", and 1" nominal pipe sizes with female NPT
threads. They employ jewel bearings to allow for very low
minimum flow rates and superior life.
The FPR300, with a body of polypropylene, is an economical
choice for metering water or low corrosion fluids. The lens
cover is available in a choice of materials: acrylic for visual
flow indication of low-corrosion fluids; polypropylene
when more corrosion resistance is needed. The standard
rotor assembly is PVDF with tungsten carbide shaft. The
O-ring is EPDM.

The FPR310 offers greater chemical resistance with a PTFE
body and cover, PTFE-coated FKM O-ring, and standard
PVDF/ceramic rotor assembly.
The pulse output of these meters is compatible with many
different types of controls, including a full range of Omega
rate displays and controls.
DPF-144 provide flow rate and total flow indication. The
DPF-144 also includes 4-20 mA output capability. The FMG-
1000-MAW may be used for blind 4-20 mA transmission.
