aluminum and is considered to constitute
a potential risk of ignition by impact or
friction. Care must be taken into account
during installation and use to prevent
impact or friction.
WARNING
Part of the enclosure is constructed from
plastic. To prevent the risk of electrostatic
sparking the plastic surface should only be
cleaned with a damp cloth.
WARNING
1. This equipment is approved to handle only
uids which are compatible with all wetted
materials.
2. When measuring ammable liquids, ob-
serve precautions against re or explosion.

3. When handling hazardous liquids, always
follow the liquid manufacturer’s safety
precautions.
4. When working in hazardous environments,
always exercise appropriate safety precau-
tions.
5. Always dispose of used cleaning solvents
in a safe manner according to the solvent
manufacturer’s instructions.
6. During turbine removal, liquid may spill.
Follow the liquid manufacturer’s safety
precautions for clean up of minor spills.
7. Do not blow compressed air through the
turbine.
8. Do not allow liquids to dry inside the
turbine.
9. Handle the rotor carefully. Even small
scratches or nicks can affect accuracy.
10. When tightening the turbine, use a wrench
only on the wrench ats.
11. For best results, always verify accuracy
before use.
FTB380 Series Turbines are identied by the
internal diameter of the inlet and outlet.
A109GMA100NA1 – 1/2 inch (Low Flow)
A109GMA100NA1 – 1 inch (Mid Flow)
A109GMA200NA2 – 2 inch (High Flow)
Each of these turbines are designed to work
with on-board display 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.
Liquids flow 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
display 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 dam-
aged or missing, contact OMEGA Customer
Service.
Make sure the turbine model meets your spe-
cic needs. Refer to the Specications Section
and conrm 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.
Information specic to your particular turbine,
including serial number and manufacturing
date is printed on the bottom of the turbine.
SN = Serial Number, a 7-8 digit number that
identies this particular turbine.
MFD = Manufacturing Date indicating the
week and year of manufacture.
For your future reference, it might be useful to
record this information in the manual in case
it becomes unreadable on the turbine.
All Series FTB380 turbines are designed to
measure ow in only one direction. The direc-
tion is indicated by the arrow cast-molded in
the turbine outlet. If the opposite direction is
desired, and you are using on-board display
electronics, rotate the display electronics 180
degrees prior to installation.
INSTALLATION
PRODUCT DESCRIPTION

Flow altering devices such as elbows, valves,
and reducers can affect accuracy. The fol-
lowing recommended guidelines are given to
enhance accuracy and maximize performance.
Distances given here are minimum require-
ments; 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 A109GMA100NA1 turbine, there
should be 10 inches (25.4 cm) of straight
pipe immediately upstream. The desired
upstream straight pipe length is 20 inches
(50.8 cm).
Downstream from the turbine, allow a mini-
mum straight pipe length at least 5 times the
internal diameter of your turbine. For ex-
ample, with the A109GMA100NA1 turbine,
there should be 5 inches (12.7 cm) of
straight pipe imme-diately downstream. The
desired downstream distance is 10 inches
(25.4 cm).
A typical back pressure of 5 to 50 PSI (0.34
to 3.4 bar) will prevent cavitation. Create
back 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 af-fect accuracy. If this problem is
anticipated or experienced, install screens to
filter impurities from incoming liquids.

All Series FTB380 turbines are Factory Mu-
tual Approved and carry a Class 1, Division 1
Approval for hazardous environments. They
are tested and calibrated at the factory using
state-of-the-art calibration procedures and
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 turbine.
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 cov-
erplate. Leave the coverplate installed unless
accessory modules specify removal.
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 arrow on the outlet is
pointed in the direction of the ow.
3. Tighten the turbine onto the ttings. Use
a wrench only on wrench ats.
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
veried prior to use. To do this, remove all
air from the system, measure an exact known
volume 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 veried periodically as
part of a routine maintenance schedule.
The display electronics is normally installed
on the turbine housing at the factory unless
ordered without it.
3
CONNECTIONS

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 FTB380 Series turbine with
an accessory module, please review and thor-
oughly understand all installation instructions
before proceeding.
Avoid electronically “noisy” environments.
Install at least 6 inches (15.2 cm) away from
motors, relays, or transformers.

OPERATION
All operations are reected in the LCD read-
out. The large center digits indicate amounts,
where smaller words or “icons” located above
and below indicate specific information
regarding totals, ow, calibration and units
of measure.
Activate the Meter
The computer is on continuously and always
ready to perform. The computer is powered
by eld replaceable batteries. When display
becomes dim, faded or the low battery mes-
sage appears (see below), the batteries need
to be replaced. Reference the Maintenance
Section for details.
Batch and Cumulative Totals
The computer maintains two totals.The Cumu-
lative Total provides continuous measurement
and cannot be manually reset. The Batch Total
can be reset to measure ow during a single
use. The Cumulative Total is labeled TOTAL
1, Batch Total is labeled TOTAL 2 BATCH.
When the Cumulative Total reaches a display
reading of 999,999 the computer will highlight
an X10 icon. This indicates to the operator that
a zero must be added to the 6 digits shown.
When the next rollover occurs, the computer
will highlight an X100 icon. This indicates to
the operator that two zeroes must be added to
the 6 digits shown.
Press the DISPLAY button briey to switch
between the TOTAL 1, TOTAL 2 BATCH
and FLOWRATE. Press DISPLAY briey
to display the TOTAL 2 BATCH. Hold the
DISPLAY button for 3 seconds to reset the
Batch Total to zero.
When uid is owing through the meter, a
small propeller icon is highlighted.
Flowrate Feature
To use this feature, press and release DIS-
PLAY button until FLOWRATE icon appears.
The factory set time base will be highlighted
to the right of FLOWRATE (M = Minutes,
H = hours, D = days). When FLOWRATE is
invoked, the display will be indicating rate
of ow.
Factory and Field Calibration
All calibration information is visible to the
user as icons on the top line of the display,
above the numeric digits.
All units are congured with a “factory”
calibration. Both gallons and litres are avail-
able (“GL” or “LT” will be displayed). While
holding the CALIBRATE button, briey press
DISPLAY to toggle between gallons and litres.
This factory calibration (indicated with FAC)
is permanently programmed into the computer
and is not user adjustable.
NOTE: Your computer may have other units of
measure programmed into it. If so, holding
the CALIBRATE button and momentarily
pressing the DISPLAY button will toggle
through all factory set units. Other pos-
sible units are: IGL (imperial gallon), QT
(quart), CF (cubic feet), CM (cubic meter),
BL (42 gal. barrel), CC (cubic centimeter)
or OZ (ounce).
Switching between different units will not
corrupt the Total’s contents. For example, in
GL mode, the computer totalizes 10.00 gallons,
if the user switches to LT mode, the display
will read 37.85 litres (the same volume, dif-
ferent unit).

5
CALIBRATION
Verify Accuracy Before
Beginning Field Calibration
For the most accurate results, dispense at a
owrate which best simulates your actual oper-
ating conditions. Avoid “dribbling” more uid
or repeatedly starting and stopping the ow.
This can result in less accurate calibrations.
Make sure you meet the meter’s minimum
owrate requirements:
A109GMA025NA1 meter.3 GPM (1.1 LPM)
A109GMA100NA1 meter 3 GPM (11.0 LPM)
A109GMA200NA2 meter 30 GPM (113 LPM)
The use of a uniformly dependable, accurate
calibration container is recommended for the
most accurate results. Due to high owrate,
it is strongly recommended that calibration
be completed with a combination of volume
and weight using ne resolution scales. For
best results, the meter should be installed and
purged of air before eld calibration.
Field Calibration with
Computer Display
Field Calibration and Factory Calibration
are dened in the Operation Section. Factory
calibration settings are programmed into each
computer during manufacturing, using stod-
dard test solvent at 70° F (21° C). Settings
are correct for light liquids such as water,
gasoline or diesel. Readings using the Factory
Calibration (FAC) may not be accurate in some
situations, for example, “heavy” liquids such
as motor oil under extreme temperature condi-
tions, non-standard plumbing congurations
or with uids other than water.
For improved accuracy under such conditions,
the computer allows for “eld” calibration, that
is, user entry of custom calibration parameters.
A “single point” calibration may yield accept-
able accuracy when used in a non-standard
application.
Field Calibration Procedures
(Dispense/Display Method)
1. To eld calibrate, press and hold the CALI-
BRATE and DISPLAY buttons for about
3 seconds until you see FLdCAL. Release
both buttons and you will see dd000.0. You
are now in the eld calibration mode.
2. Dispense a known amount of uid at a
owrate representative of the application.
Any amount between 000.1 and 999.9
units can be used. Display will count up
while uid is owing through the meter.
3. The DISPLAY button can then be pushed
to select the digit location and the CALI-
BRATE button can be pushed to scroll
the desired value at the blinking position.
Edit the amount shown with the value that
was dispensed above. Values from 000.1
to 999.9 can be entered.
4. When satised with the value, press both
CALIBRATE and DISPLAY buttons si-
multaneously. CALEnd will be displayed
and unit will go back to normal operation,
less the FAC (factory calibration) icon.
5. The meter will now be operating with a
custom calibration number unique to the
above dispense procedure. No unit of
measure (gallon, litre, etc.) icon will be
highlighted
NOTE: To return to factory calibration (FAC),
press and hold both CALIBRATION and
DISPLAY buttons for about 3 seconds,
until FAcCAL is displayed. Then release
buttons. Unit should return to normal
operation and FAC icon visible
NOTE: If the eld calibration mode is entered
and NO uid is dispensed, then upon leav-
ing, the computer will use data from the
last successful eld calibration.
The “eld” calibration may be set by the user,
and can be changed or modied at any time
using the calibration procedure described in
the Calibration Section. Totals or owrate
derived from the eld calibration are invoked
when the FAC icon is no longer visible on the
top line of the display.

MAINTENANCE
Verify Accuracy
Before use, check the turbine’s accuracy and
verify calibration.
1. Make sure there is no air in the system.
2. Measure an exact known volume into an
accurate container.
3. Verify the volume against the readout or
recording equipment.
For best results, accuracy should be veried
periodically as part of a routine maintenance
schedule.
Remove the Turbine
1. Ensure all liquid is drained from the tur-
bine. Wear protective clothing as necessary.
2. Loosen both ends of the turbine. Use a
wrench only on the turbine’s wrench ats.
3. If the turbine is not immediately installed
again, cap lines as necessary.
Clean the Turbine
During use, the turbine should be kept full
of liquid to ensure that drying does not occur
inside the turbine. If drying or caking should
occur, the rotor will stick or drag, affecting
accuracy. To determine if the rotor is stuck or
dragging, gently blow air through the meter
and listen for the quiet whir of the rotor.
During turbine removal, liquid may spill.
Follow the liquid manufacturer’s safety
precautions for clean up of minor spills.
WARNING
CAUTION
Never blow compressed air through the
meter. It could damage the rotor.
Follow the liquid manufacturer’s in-
structions for the disposal of contami-
nated cleaning solvents.
WARNING
1. Remove the turbine from the system fol-
lowing the directions above.
2. When the rotor turns freely, assemble and
install it again following the instructions
above.
Display Electronics
The display electronics are powered by
lithium batteries which provide at least four
years of actual use. If the meter’s readout
should become dim, blank or the low battery
message appears (see below), the batteries
should be replaced. Replacement batteries
can be ordered from the factory. See details
in the Parts Section.
When batteries are disconnected or fail,
values in Batch and Cumulative Totals will
remain. Factory and Field Calibration Curves
are retained in the meter’s computer when
power is lost.
It is strongly recommended that battery check
and terminal cleaning be a part of a routine
maintenance schedule. Battery terminals
should be cleaned annually. Batteries can be
replaced without removing the meter from the
piping system.

Replacing the Batteries
1. Remove the corner screws from the meter
face and lift the display electronics from
the turbine.
2. Remove the batteries.
3. Check the battery terminals and remove
any corrosion.
4. Install the new batteries and make sure
the positive posts are positioned correctly.
When the batteries are installed correctly,
the computer powers on automatically
and the readout displays information.
5. Make sure the seal is fully seated before
placing the computer electronics on the
turbine. Tighten the four screws.
