The FTB-100 Series of turbine
meters have a shielded ball bearing
design for high-accuracy
performance (±0.5% of reading, not
full scale) at an economical cost.
The non-metallic bearing retainers
minimize friction, thereby allowing
these meters to be used with clean
fluids that have poor lubricating
properties (i.e., water). Ball bearings
also give the widest linear flow
range, particularly in larger turbines.
Bearing replacement and clean-up
are fast and easy, since all internal
parts are easily accessible by
removing a single nut.
These turbine flowmeters have a low
mass rotor design which allows rapid
dynamic response, so they can be
used in pulsating flow applications.
Deflector cones eliminate
downstream thrust on the rotor and
allow hydrodynamic positioning of
the rotor between the cones. This
provides wider rangeability and
longer bearing life than conventional
turbine flowmeters. Integral flowstraightening tubes minimize the
effects of upstream turbulence.

shown actual size.
OMEGA®high accuracy integral
signal conditioners are designed for
direct mounting onto OMEGA
FTB-100 and 200 Series turbine
meters. The input circuitry of the
signal conditioners has been
designed to receive and condition
low level turbine meter signals while
rejecting unwanted noise and
spurious signals. A signal threshold
control is provided which allows the
user to set the input sensitivity
above the ambient noise level,
thereby eliminating any false
signal on the output. Signal
conditioners are available that can
provide 4 to 20 mA, 0 to 5V, and
scaled frequency pulse outputs
that run on unregulated power
supplies. Other units which run
off 115 Vac provide both an
unscaled pulse output and a
0 to 5V or 4 to 20 mA output.
A zero and a span potentiometer
allow for simple field adjustment
of the analog outputs from the
signal conditioners.

explosion-proof or intrinsically safe. It is the user’s responsibility to determine the suitability
of materials for a given installation.
