Important Notice
The 01A Series meter is for use with
gasoline, diesel fuel and kerosene only.
Do not use to meter water or chemicals.
Do not use for measuring fuel or other
liquids into aircraft.
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 Teflon®tape. Ensure the tape
does not intrude into the flow path.
3. Attach meter to hose with arrow on outlet
port pointed in the direction of flow.
4. Attach nozzle to meter. If necessary,
use the enclosed 3/4-inch fitting.
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 briefly to switch
between them. The batch total may be
reset to measure flow 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 flow or briefly 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 briefly 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.
CAUTION
Blowing compressed air through
the turbine assembly could
damage the rotor.
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.
