FTB700 SERIES INSTRUCTIONS
Page 4 omega.com
This unique system of 3" to 8" turbine meters uses just one
moving part, a precision helical rotor. Rotation of the rotor is
electronically detected and processed. The high-quality jewel
bearings and shafts minimize friction while providing long life
in non-lubricating fluids. The entire rotor assembly can be easily
removed for field service without removing the meter from the
pipe.
FTB700 bodies are fabricated from Schedule 80 PVC fittings or
from stainless steel tubing. The turbine insert on the stainless
steel meters is machined from a stainless steel casting. The PVC
turbine insert is machined from a solid piece of PVC. Turbine
rotors on all models are PVDF.
FTB700 meters can be ordered with various output options. The
basic model comes with pulse output only. An electronic display
is available on the DPF144-P/DPF144-W model to display flow
rate and total (resettable or non-resettable), and provide a
programmable pulse or 4-20 mA output. The controls/displays
can be mounted on the meter or remotely mounted on a wall
or panel up to 2,000 feet away. FTB700 meters are compatible
for use with other remote-mount Omega displays and controls
as well.
