OPW Installation and Maintenance Instructions
OPW 200TG Mechanical AST Liquid Level Gauge
IMPORTANT: Please read these warnings and use
the assembly instructions completely and carefully
before starting. Failure to do so may cause product
failure, or result in environmental contamination due
to liquid leakage into the soil, creating hazardous spill
conditions.
IMPORTANT: The OPW 200TG Tank Gauges are
pre-assembled for your convenience and ease of
use. Check to make sure the unit is intact and
undamaged and all parts have been supplied. Never
substitute parts for those supplied. Doing so may
cause product failure.
WARNING-DANGER: Using electrically operated
equipment near gasoline or gasoline vapors may
result in a fire or explosion, causing personal injury
and property damage. Be sure that the working area
is free from such hazards, and always use proper
precautions.
NOTE: At all times when product is in the storage
tank keep the riser pipe capped, so the vapors
cannot escape into the environment.

200TG Installation Instructions
Step 1
For maximum accuracy, calibration should be
undertaken when the tank is half full. Using a
dipstick, measure and record tank fluid level in feet
and inches. If tank is empty, record level as 3.75
inches.
Step 2
Remove tank gauge from packaging. Be sure to
keep the cable taut before installation.
Step 3
If installing a drop tube, drill a 5/16” vent hole within
6 inches from the top of the drop tube.
NOTE: Drop tubes are highly recommended for use
in tanks that have any components near the tank
gauge operating space in which the float and cable
could become entangled, or in any tanks in which
there is a high amount of turbulence. OPW offers a
line of 61T Drop Tubes specifically for the 200TG.
Step 4
Apply pipe dope to threads on swivel base to
ensure a tight seal. Pipe dope is to be a non-
hardening, gasoline resistant pipe thread sealant
compound.
Step 5
Thread swivel base onto desired tank opening and
tighten to 80 ft-lbs.
Step 6
Rotate tank gauge to desired orientation for best
visibility.
Step 7
Remove the eight (8) bolts from the top of the
gauge. Place them, the cover and the lid gasket in
a safe place. Be careful not to damage the lid
gasket.
Step 8
While supporting the float, remove the cardboard
insert that is holding the drive gear in place. (See
Figure 2.)
WARNING: When this cardboard piece is removed
the spool is no longer secured. It is necessary to
hold the float to prevent the spool from tangling.
This insert must be removed for operation of the
gauge.
Figure 2
Step 9
Slowly lower the float into the desired tank opening.
Remember to keep the cable taut at all times.
Step 10
From the inside of the tank-gauge housing,
disengage the gears by sliding them toward the
spring at one end of the housing to allow for
calibration of gears. While the gears are
disengaged, start by rotating the inch gear to the
match the inch value found in Step 1. Slide this
gear away from the spring to re-engage. Repeat for
two remaining gears. Be sure to view the gauge

from the vantage point it will be viewed from in day-
to-day operations to properly calibrate the gears.
(See Figure 3.)

Step 11
Place the lid gasket back into the groove, being
careful not to damage it and keep it clean from
debris. No sealant is necessary for this gasket. Add
the cover and secure it tightly with the eight (8)
bolts, using a crossing pattern, torque the bolts to
15-20 ft-lbs.
Annual Maintenance:
Using a dip stick, measure the liquid level of the
tank and check this value with the value displayed
on the tank gauge. The values should be within ±2
inches of each other. Recalibrate if necessary.
Remove cover and visually inspect the internal
parts for signs of wear, tangles in the spool, and
corrosion. Replace parts if necessary.
