OMEGA® FTB700 Series turbine
meters have a unique system of
precisely-machined helical rotors
and high-quality jewel bearings.
The rotor is the only moving part.
Small magnets on the rotor hub are
electronically detected by a solid
state Hall-effect sensor outside the
wetted area. The turbine rotor uses
journal-type sapphire and ruby
bearings for minimum friction and
maximum life. These bearings are
ideal for long life in water and
water-based fluids, and they have
exceptional low-flow characteristics.
The entire rotor assembly (rotor,
hubs, bearings, rotor strut) can be
removed from the meter as a single
unit without removing the meter
from the pipe.
