Operations Guide for
01A Series
Electronic Digital Fuel Meter
GENERAL INFORMATION
Congratulations on receiving your GPI
fuel meter. These instructions will help
you operate and maintain your meter.
Content covered in these instructions
include all models in the 01A Series of
Electronic Digital Fuel Meters.
This meter is designed for use only
with gasoline (up to 15% alcohol blends
such as E15), diesel fuel (up to 20%
biodiesel blends such as B20), biodiesel
(B100) and kerosene. Do NOT use it with
water, chemicals or for measuring fluids
into aircraft. This meter is not legal for
trade applications. The 01A Series meter is
very sensitive to electrical "noise" and
may not operate correctly if located near
some electrical equipment. This meter has
a permanent factory calibration for
measuring gasoline, diesel fuel or
kerosene. If installed and used correctly,
you can expect accuracy within ±5%.
INSTALLATION
Install the meter at the end of the hose
adjacent to the nozzle or horizontally or
vertically in-line. Make sure all threaded
fuel connections are wrapped with three to
four turns of thread tape or pipe thread
sealant approved for use with petroleum
fuels. Make sure the tape does not intrude
into the flow path. Attach the meter to the
hose with the arrow on the outlet port
pointed in the direction of flow. Use
fittings as necessary. Use a wrench at the
housing ends to tighten the meter.
OPERATIONS
This meter will turn on automatically
when it senses fuel flow. It can manually
be turned on by pressing the DISPLAY
button ("DISPLAY"). The meter will show
the total from its last use. The meter turns
off automatically if not used for about one
minute.
Totals
This meter maintains two totals. The
batch total ("TTL1") may be reset to zero
and measures flow during a single use. The
cumulative total ("TTL2") provides
continuous measurement and may not be
manually reset. When the cumulative total
reaches a maximum reading of 9999, it
automatically resets to zero.
Press the DISPLAY button ("DIS-
PLAY") briefly to switch between TTL1
and TTL2. With TTL1 showing, hold the
DISPLAY button down for three seconds
to zero the batch total.
