Product Description
Omega Industrial Meter Turbines are identi-
ed by the internal diameter of the inlet and
outlet.
FTB891 - 1/2 inch
FTB893 - 1 inch
Each turbine is designed to work with onboard computer electronics and/or with one of
several accessory modules that can interface
to a wide variety of reporting and collecting
devices.
The CMOS microprocessor-based electronics
have extremely low power requirements and
data retention capabilities in both RAM and
ROM. Information is clearly displayed on
a large 6-digit LCD readout with two-point
oating decimal for totals from .01 to 999,999.
All operations are easily accessed with the two
buttons on the front panel.
Liquid ows through the turbine housing causing an internal rotor to spin. As the rotor spins,
an electrical signal is generated in the pickup
coil. The electrical signal provides the output
necessary to operate the on-board computer
electronics for local indication directly on the
turbine or one of several accessory modules
that transmit the signal to external equipment.
Upon receipt, examine your meter for visible
damage. The turbine is a precision measuring
instrument and should be handled as such.
Remove the protective plugs and caps for a
thorough inspection. If any items are damaged
or missing, contact your distributor.
Make sure the turbine model meets your spe-
cic needs. Refer to the Specications Section
and conrm the following:
1. The owrate is within the limits of your
model.
2. The liquid is compatible with the turbine’s
wetted components.
3. The system’s pressure does not exceed
the turbine’s maximum pressure rating.
Each Omega Turbine has a unique identica-
tion number that includes the Serial Number,
Model Number, Manufacturing Date, and
K-Factor. This identication number is etched
into the surface of the turbine. Record this
identication number in the back of the Owner’s Manual and keep for future reference.

INSTALLATION
All Omega turbines are designed to measure
ow in only one direction. The direction is
indicated by the arrow cast-molded in the
turbine outlet. If the opposite direction is
desired, and you are using on-board computer
electronics, rotate the computer electronics
180 degrees prior to installation.
Flow altering devices such as elbows, valves,
and reducers can affect accuracy. The following recommended guidelines are given to
enhance accuracy and maximize performance.
Distances given here are minimum requirements; double them for desired straight pipe
lengths.
Upstream from the turbine, allow a minimum
straight pipe length at least 10 times the in-
ternal diameter of the turbine. For example,
with the FTB893 turbine, there should be 10
inches (25.4cm) of straight pipe immediately
upstream. The desired upstream straight pipe
length is 20 inches (50.8cm).
Downstream from the turbine, allow a minimum straight pipe length at least 5 times the
internal diameter of your turbine. For example, with the FTB893 turbine, there should
be 5 inches (12.7cm) of straight pipe immediately downstream. The desired downstream
distance is 10 inches (25.4cm).
A typical back pressure of 5 to 50 PSI (0.34 to
3.4 bar) will prevent cavitation. Create back
2
pressure by installing a control valve on the
downstream side of the meter at the proper
distance detailed above.
Foreign material in the liquid being measured
can clog the turbine’s rotor and adversely affect accuracy. If this problem is anticipated or
experienced, install screens to lter impurities
from incoming liquids.

The PVDF Series FTB890 turbines are Factory Mutual Approved and carry a Class 1,
Division 1 Approval for hazardous environments. Omega Meters are tested and calibrated
at the factory using state-of-the-art calibration
test equipment.
To ensure accurate measurement, remove all
air from the system before use. To purge the
system of air:
1. Ensure some back pressure on the tur
bine.
2. Open the discharge valve or nozzle and
allow uid to completely ll the system.
Make sure the stream is full and steady.
3. Close the discharge valve or nozzle.
4. Start normal operations.
Each turbine contains a removable back coverplate. Leave the coverplate installed unless
accessory modules specify removal.

Connections
1. To protect against leakage, seal all threads
with an appropriate sealing compound.
Make sure the sealing compound does
not intrude into the ow path.
2. Make sure the ow direction arrow on
housing back is pointed in the direction
of the ow.
3. Install union ring over pipe end prior to
installing pipe tting.
4. Install pipe ttings on pipe ends, and
tighten.
5. Tighten union ring to the turbine. Make
sure O-ring is positioned in housing ends.
Do not use a wrench or pliers. Hand
tighten only.
NOTE: If connecting to new male threads,
burrs and curls can adversely effect
accuracy. Correct the problem prior to
turbine installation.
It is strongly recommended that accuracy be
veried prior to use. To do this, remove all air
from the system, measure an exact known vol-
ume into an accurate container, and verify the
volume against the readout or recording equipment. If necessary, use a correction factor to
gure nal volume. For best results, accuracy
should be veried periodically as part of a
routine maintenance schedule. The procedure
is found in the Maintenance Section.
The display electronics is normally installed
on the turbine housing at the factory unless
ordered without it.
If for any reason the display electronics
need to be mounted on your turbine, simply
mount the display on the turbine with the four
screws at the corners of the faceplate. Make
sure the seal is fully seated before tightening
the screws.
If you ordered the FTB890 Series turbine with
an accessory module, please review and thoroughly understand all installation instructions
before proceeding.
Avoid electronically “noisy” environments.
Install at least 6 inches (15.2cm) away from
motors, relays, or transformers.

OPERATIONS
All operations are reected in the LCD readout. The top line identies the calibration
curve. The middle line reects ow informa-
tion. The bottom line shows information from
the totalizer. Words or “ags” display on the
top and bottom line to further identify specic
information.
The display electronics is powered by eld
replaceable batteries. When the readout becomes dim or faded, the batteries need to be
replaced. Reference the Maintenance Section
for details.
NOTE: Operations can be practiced prior to
installation. To simulate ow conditions,
blow gently through the turbine.
Turn On
The meter is on when any display is present.
It turns on automatically when liquid ows
through the meter. It can be turned on manually by pressing and releasing the DISPLAY
button.
Turn Off
The meter turns off automatically approximately four minutes after ow stops. When
the meter is off, the readout is blank.
Figure 2
To change between totals, press and release
DISPLAY.
NOTE: Generally, readout displays change
when buttons are released.
Factory and Field
Calibration Curves
All calibration information is visible to the
user as words in the upper part of the display,
above the numeric digits.
All units will be congured with a “factory”
calibration curve, for which units of gallons
or litres may be selected by the user (“GAL”
or “LTR” will be visible). This curve is NOT
user adjustable: the word “PRESET” is
displayed to show this. (See Figure 3) The
factory calibration is stored permanently in
the computer’s memory.
Figure 3
Batch and Cumulative Totals
Total ags are displayed on the bottom line. A
Batch Total indicates ow during a single use.
It is labeled with TOTAL 2. To zero a batch
total, make sure it is displayed and hold down
DISPLAY for three seconds until the display
changes to zeros.
The Cumulative Total is the total of all liquid
measured since the meter’s power was con-
nected. At your rst use, the Cumulative Total
is not zero because of calibration at the factory.
The Cumulative Total is labeled as TOTAL
LOCKED indicating it cannot be manually
zeroed. (See Figure 2) The Cumulative Total
is zeroed only when batteries are removed or
go dead or when the Cumulative Total reaches
the maximum value of 999,999.

The “eld” calibration curve may be set by the
user, and can be changed or modied at any
time using the calibration procedure described
below in the CALIBRATION section. Totals
or owrate derived from the eld calibration
are visible when the eld calibration setting
(CAL B) is selected.
