GENERAL INFORMATION
Congratulations on receiving your GPI wa-
ter meter. These instructions will help you
operate and maintain your meter. Content
covered in these instructions include all
models in the 01N Series of Electronic Digi-
tal Water Meters.
This meter is designed for use only with
water. Do NOT use with gasoline, diesel fuel
or kerosene. This meter is not legal for trade
applications. The 01N Series meter is very
sensitive to electrical "noise" and may not
operate correctly if located near some elec-
trical motors. This meter has a permanent
factory calibration for measuring water. If
installed and used correctly, you can ex-
pect accuracy within ± 5%.
INSTALLATION
Install the meter at the end of the hose ad-
jacent to the nozzle or horizontally or verti-
cally in-line. Apply pipe sealant to all
threaded connections. Attach the meter to
the hose with the arrow on the outlet port

pointed in the direction of flow. Use fittings
as necessary. Hand tighten only. Do not
over tighten as housing can be damaged.
OPERATIONS
This meter will turn on automatically when
it senses fuel flow. It can manually be turned
on by pressing the DISPLAY button ("DIS-
PLAY"). The meter will show the total from
its last use. The meter turns off automati-
cally 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 continu-
ous measurement and may not be manu-
ally reset. When the cumulative total
reaches a maximum reading of 9999, it au-
tomatically resets to zero.
Press the DISPLAY button ("DISPLAY")
briefly to switch between TTL1 and TTL2.
With TTL1 showing, hold the DISPLAY but-
ton down for three seconds to zero the
batch total.
MAINTENANCE
This meter is virtually maintenance free if
the meter is kept clean and free of contami-
nants. It is important that the rotor moves
freely. Apply a penetrating lubricant on the
rotor, shaft, and bearings if the rotor sticks.
Use a soft brush or small probe to remove
debris from the rotor. If compressed air is
blown through the turbine assembly, it
could damage the rotor.
