These versatile impeller flowmeters are available in 3/8",
1/2”, 3/4”, and 1" nominal pipe sizes with female NPT
threads (SAE optional). They employ jewel bearings to allow
for very low minimum flow rates and superior life.
With a body material of polypropylene, the
FPR300
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-corrosive fluids; polypropylene
when more corrosion resistance is needed. The standard ro-
tor assembly is Kynar with tungsten carbide shaft (ceramic
shaft optional). The O-ring is EPDM.
The
FPR310
offers greater chemical resistance with a TFE
body and cover, TFE-coated Viton O-ring, and standard Kynar/
ceramic rotor assembly (silicon carbide shaft optional).
The pulse output of these meters is compatible with many
different types of controls, including a full range of Omega rate
displays and controls. The Omega DPF75-A provides flow rate
and total flow indication, with 4-20 mA ouput capability.
