The meter translates flow data from the
nutator disc into calibrated units shown
on the meter’s readout. A field replace-
able battery provides power.
Upon receipt, examine your meter for
visibledamage.Removeprotectiveplugs
and caps for a thorough inspection. If
any items are damaged or missing, con-
tact your distributor.
CAUTION: To avoid damage, DO NOT
blow compressed air through the
meter.

To save power, this meter is shipped with
the battery disconnected. Before using,
connect the battery using the instruc-
tions below:
1. Remove the two large and two small
screws from the battery coverplate
located on the lower portion of the
meter face.
2. Remove the battery and plug into
battery connections. When con-
nected properly, numbers appear in
the meter readout.
3. Replace the gasket and battery
cover and tighten securely. Torque
the screws to 9 to 10 in. lbs.
BEFORE INSTALLATION
INSTALLATION
NOTE: To avoid damage to the inlet and
outlet, install this meter ONLY on
plastic hose end or pipe fittings.
1. To protect against leakage, seal all
threads with two or three turns of
Teflon®tape or a pipe thread seal-
ant compatible with the liquid being
measured. Make sure the Teflon®
tape or sealant does not interfere
with flow.
2. Hand-tighten the meter onto the fit-
tings until snug. (Figure 1)
Figure 1
CAUTION: To avoid damage to the
housing, do not use a wrench.
If the meter has been used before, make
sure it is flushed and cleaned as outlined
in the Maintenance Section.
Press and release the DISPLAY button
to ensure the meter is operating. Num-
bers will display from the last use.
If the display is dim or fading, replace the
battery using instructions in the Mainte-
nance Section. Also check battery ter-
minals for corrosion. To prevent corro-
sion from condensation, coat the termi-
nals with petroleum jelly.
BEFORE EACH USE

4
Verify Meter Accuracy
Beforeusing,verify calibration and check
the meter’s accuracy.
1. If desired, hold down DISPLAY for
three seconds to zero the meter’s
Batch Total. When zeros appear, re-
lease the button.
2. Meter an exact known volume into
an accurate container. For best re-
sults, meter with one continuous full
stream.
3. Check the readout. If the amount
metered is accurate, field calibration
is not needed. If not, refer to the
Calibration Section for further in-
structions.
NOTE: Best performance can be ob-
tained by using the factory calibra-
tion.
All meter operations are reflected in the
readout on the face of the meter.
The readout contains three lines of infor-
mation. They are generally defined as
follows:
•The top line indicates the calibra-
tion curve.
•The middle line reflects flow infor-
mation.
•The bottom line shows information
from the totalizer.
The words or “flags” that display on the
top and bottom line further identify spe-
cific information.
OPERATIONS
! ! ! WARNING ! ! !
This meter is approved to handle
water, pesticides, fertilizers, and
most industrial fluids. Do not use for
gasoline, diesel, or other fuels. Do
not use this meter with flammable
liquids.
Turn On
The meter is on when any display is
present. It turns on automatically when
liquid flows through the meter. It can be
turned on manually by pressing and re-
leasing the DISPLAY button.
Turn Off
Whenever no flow has been sensed for
one minute, the unit automatically
switchestoapower-saving“sleep”mode
with a blank display. The unit will auto-
matically “wake up” the moment any
flow is sensed and will remain awake as
long as fluid is flowing. Totals are never
lost during sleep periods.
Batch and Cumulative Totals
Total flags are displayed on the bottom
line. The Cumulative Total is the total of
all fluid measured since the meter’s
power was connected.
NOTE: At your first use, the Cumulative
Total may not read zero because of
calibration at the factory.
The Batch Total (labeled TOTAL 2) indi-
cates flow during a single use. (Figure 2)
Clearing a Totalizer
The Batch totalizer register (TOTAL 2)
may be independently cleared to 0.00 at
any time. To clear a Batch totalizer, with
the desired totalizer displayed, press
and hold the DISPLAY button. At about
3 seconds, the displayed total will be
cleared to “0.00”. You can do this even
while fluid is flowing, in which case,
counting will resume after you release
the DISPLAY button.
Figure 2

CALIBRATION
The Cumulative totalizer register is la-
beled as TOTAL 1 LOCKED indicating
that it cannot be manually zeroed (Fig-
ure3). The Cumulative totalizeris cleared
only when the batteries are removed or
go dead or when the Cumulative Total
reaches the maximum value of 999,999.
Figure 3
Changing Display Registers
During normal operation, to change to
another totalizer register or to FLOW-
RATE mode, watch the bottom line dis-
play flags while you briefly press and
release the DISPLAY button. With each
operation, the mode will advance as
follows: TOTAL 1 LOCKED (Cumulative
Total), TOTAL 2 (Batch Total), FLOW-
RATE, TOTAL 1 LOCKED (etc.). You can
change registers at any time, even dur-
ing flow. Non-visible totalizer registers
will continue to accumulate.
NOTE: Generally, display registers
change when the buttons are re-
leased. Also, not all models include
the FLOWRATE mode.
Factory and Field Calibration
Curves
GPI flow computers have enhanced cali-
bration features. All calibration informa-
tion is visible to the user as words in the
upper part of the display, above the
numeric digits. There are two types of
calibration curves: Factory Calibration
and Field Calibration.
Factory Calibration curves are “preset”
by the manufacturer and stored perma-
nently in the computer’s memory. Fac-
tory calibration curves always display
PRESET on the top line of the readout
(refer to Figure 2). Factory Calibration is
either in gallons or litres.
A Field Calibration curve is set by the
user. The field calibration curve may be
changed or modified at any time using
the calibration procedure described in
this Section. Totals or flowrate derived
from the field calibration are visible when
the field calibration setting is selected.
All units are configured with two Factory
Calibration curves and one Field Cali-
bration curve:
•Factory Calibration curve for thin
viscosity liquids (GAL or LTR PRE-
SET is displayed).
•Factory Calibration curve for me-
dium to thick viscosity fluids (CAL
B PRESET is displayed).
•Field Calibration curve (CAL C is
displayed).

6
Selecting a Different
Calibration Setting
To select a different calibration setting,
first press and hold the CALIBRATE but-
ton. Continue to hold it while also briefly
pressing and releasing the DISPLAY
button. (You may then also release the
CALIBRATE button.) The flag indicators
in the upper area of the display will
change to show the newly selected cali-
bration setting. Calibration settings
change in this order: GAL or LTR, CAL B,
CAL C (etc.). While fluid is flowing, only
the GAL or LTR or CAL B selections may
be made, however, when NO fluid flow is
occurring, any setting may be selected.
Flowrate Mode
Some models include a Rate of Flow
feature (accessed by briefly pressing
and releasing the DISPLAY button as
described above). When this feature is
activated,the word FLOWRATE displays
to the left of the bottom line and the
numbers in the middle of the display
reflect the rate of flow (instead of total).
Most units are set to update the display
every 5 seconds, so the first reading
after flow starts or changes and the last
reading after flow stops or changes will
be correct. This is normal.
Propeller
A small propeller displays to indicate
liquid is flowing through the meter.
Field Calibration
Factory calibration settings are custom-
programmed into each flowmeter dur-
ing production, and are correct for light
fluids such as water or heavier liquids
likepesticides or light oil.However, read-
ings using the standard factory calibra-
tion curves may not be accurate in some
situations – variations in chemical for-
mulation, viscosity, temperature, and
flowrates all effect meter accuracy. To
ensure accuracy, it is important to check
accuracy frequently and field calibrate
when necessary.
Calibration Container
The desired calibration container should
beuniformly dependable andconstructed
with a graduated neck. The container’s
volume indicator should be clearly and
precisely marked. It is helpful if the
container’s material allows a window
through which the level of liquid can be
viewed. GPI offers a properly designed
calibration container for volumes of 5
gallons or 5 litres.
DO NOT use several smaller containers
or a larger container with a 5-gallon
marking.
For the most accurate results, dispense
at flowrates that best simulate your ac-
tual operating conditions. Avoid “drib-
bling” more fluid or repeatedly starting
and stopping the flow. These actions will
result in less accurate calibrations.
Up to 15 points can be field calibrated
on the field calibration curve. This multi-
point field calibration can improve accu-
racywhenoperatingcharacteristics(usu-
ally flowrate) are not uniform. For ex-
ample, if you plan to measure flowrate
that varies widely, a multi-point field
calibration at different flowrates can im-
prove accuracy.
During calibration, make sure you meet
the meter’s minimum flowrate require-
ments of 2 GPM (7 LPM).
Before calibrating, purge the system of
air using instructions in the Before Each
Use section.

MAINTENANCE
This meter is virtually maintenance free.
It is important, however, that the nutator
disc moves freely.
To prevent drying of chemical on inter-
nal assemblies, meters should be kept
free of chemical when not in use for
extended periods of time. Flush and
clean after each use to promote trouble-
free operation.
Removal
1. Ensure all chemical is drained from
the meter. This could include drain-
ing the hose, meter, and nozzle.
2. Wearing protective clothing, loosen
the meter from fittings by hand.
CAUTION: To avoid damage to the
housing, do not use a wrench.
If the meter is not immediately installed
again, cap the hose end to prevent spills
and drying. The nozzle could be used for
this purpose. Flush the meter if it will not
be in use for more than two weeks.
Flushing
When removed or not in use for more
than two weeks, flush the meter to re-
move chemical residue.
CAUTION: Do not submerge the meter.
If needed, clean the meter using Clean-
ing instructions below.
! ! ! WARNING ! ! !
Duringmeterremoval,chemical may
spill. Follow the chemical manu-
facturer’s safety precautions for
cleanup of minor spills.

Cleaning
During use, the meter should be kept
free of liquid to ensure drying does not
occur inside the meter. If drying should
occur, the nutator will stick or drag,
affecting accuracy. If this occurs, clean-
ing is required.
Cleaning the Nutator
1. Loosen the screws on the back of
the meter about 1/4 inch (0.6 cm).

Storage
After thoroughly cleaning the meter, dis-
connect the battery and store the meter
in a clean, dry location.
Battery Replacement
Your meter is equipped with a field-
replaceable 9-volt alkaline battery.
If the meter’s readout should become
dim or blank, replace the battery.
When the battery is disconnected or
fails, the Batch and Cumulative Totals
return to zero.
Factory and Field Calibrations are not
lost when the battery is replaced or
power is lost. They are saved in the
meter’s computer and are available after
a new battery is installed. You do not
need to repeat Field Calibration.
Check the battery and terminals at least
every year to ensure proper operation. It
is strongly recommended that terminals
be cleaned annually.
NOTE: The battery can be replaced
without removing the meter from the
hose or pipe.
To replace battery or clean terminals:
1. Remove the two large and two small
screws from the battery coverplate
located on the lower portion of the
meter face. (Figure 9)
Figure 9
2. Remove the battery coverplate and
gasket. (Figure 10)

3. Remove the battery and, if neces-
sary, clean corrosion from the bat-
tery terminals. (Figure 11) To prevent
corrosion from condensation, coat
the terminals with petroleum jelly.
Figure 11
4. Install the new battery.
When the battery is installed cor-
rectly, the computer powers on au-
tomatically. Check the readout to
make sure normal meter functions
have resumed before assembling
again. If necessary, seat the battery
again.
5. Make sure the coverplate gasket is
in good condition and properly seat-
ed. Replace, if needed.
6. Replace the battery cover. Torque
the screws to 9 to 10 in. lbs.
