IMPORTANT NOTICE
The 01A Series meter is for use with
gasoline, diesel fuel and kerosene only.
Do not use to meter water or chemicals.
This meter is not legal for trade application.
The 01A Series meter is very sensitive to
electric signals if operated within one to
two inches of some electric motors.
BATTERY CONNECTION
1. Remove the four Phillips-head screws
and lift the faceplate from the meter.
2. Remove tape from the end of one
battery.
3. Place the battery back and make
sure the positive post is in the correct
position.
4. Make sure the O-ring is fully seated
and secure the faceplate with the four
screws. The O-ring may need to be
stretched to seat properly.
CALIBRATION
This meter has a permanent factory
calibration for measuring gasoline, diesel
fuel or kerosene. If installed and used
correctly, inaccuracies of no greater than
+5% will be obtained.
INSTALLATION
Install the meter at the end of the fuel hose
adjacent to the nozzle. This meter may
also be installed in-line either horizontally
or vertically. Install as follows:
1. Remove nozzle from hose.
2. Wrap all connections with 3 to 4 wraps
of Teon®tape. Ensure the tape does
not intrude into the ow path.
3. Attach meter to hose with arrow on
outlet port pointed in the direction
of ow.
4. Attach nozzle to meter. If necessary,
use the enclosed 3/4-inch tting.
5. With a wrench, tighten the meter at the
housing ends.
OPERATION
Batch and Cumulative Totals
The 01A Series meter maintains two
totals. Press the DISPLAY button briey
to switch between them. The batch total
may be reset to measure ow during a
single use. The cumulative total provides
continuous measurement and may not be
manually reset. When the cumulative total
reaches a maximum reading of 9999, it will
automatically reset to zero.
The batch total will display as TTL1 and
the cumulative total as TTL2.
Activate the Meter
Turn the 01A Series meter ON by starting
fuel ow or briey pressing the DISPLAY
button. The meter will display the batch or
cumulative total from last use.
The meter is programmed to conserve
power by automatically turning OFF if not
used for one minute.
Reset Batch Total
Press DISPLAY briey to display the batch
total. Hold the DISPLAY button for three
seconds to reset the batch total to zero.
MAINTENANCE
Proper handling and care will extend the
life and service of the meter.
Turbine Rotor
The 01A Series meter is virtually
maintenance-free. However, it is important
that the rotor moves freely. Keep the meter
clean and free of contaminants.
If the rotor does not turn freely, apply a
penetrating lubricant on the rotor, shaft and
bearings. Remove any debris or deposits
from the rotor using a soft brush or small
probe. Be careful not to damage the turbine
rotor or supports.
Blowing compressed aire through the turbine
assembly could damage the rotor.
CAUTION
Battery Replacement
The 01A Series meter is powered by two
AAA alkaline batteries, which may be
replaced while the meter is installed. When
batteries are removed or lose power, the
batch and cumulative totals reset to zero
but the factory calibration is retained.
If the meter display becomes dim or blank,
replace the batteries as follows:
1. Remove the four Phillips-head screws
from the face of the meter and lift the
faceplate from the turbine.
2. Remove the old batteries and clean any
corrosion from the terminals.
3. Install new batteries, ensuring the
positive posts are in the correct
position.
4. When the batteries are replaced, the
faceplate will power ON. Check the
display to ensure normal functions
have resumed before reassembling.
5. Reseat batteries, if necessary, and
position the faceplate on the turbine
housing. To avoid moisture damage,
make sure the O-ring is fully seated.
The O-ring may need to be stretched to
seat properly. Tighten the four screws
on the faceplate.
