FULL VIEW CONTENTS GAUGE MAINTENANCE
The content of these containers is measured with the Full View Contents Gauge. The
device consists of the gauge assembly beneath a clear plastic protective cover. When the
gauges is assembled, a level indicator ring is magnetically coupled to the top of a float
road and moves up or down with the changing level of liquid in the container. The clear
cover over the gauge body and level indicator is sealed at assembly to resist fogging of the
gauge. This seal should never need to be broken.

WARNING:
Cold surfaces should
never be handled with
bare skin. Use gloves
and other protective
clothing when
performing this
procedure.
REMOVING THE FULL VIEW CONTENTS GAUGES
1. Vent all pressure from container.
2. Remove the protective coating by removing three bolts from the base of the cover.
3. Unscrew the gauge body using a wrench on hex fitting at base of the indicator.
4. Lift the entire gauge assembly free of the container. The gauge assembly is long and
may be very cold. Gloves should be used to protect your skin.
Calibration Procedure for Liquid Level Contents Gauges
1. You will need a column of water approximately 4 ft. (1.2 m) tall. A clear plastic tube 2.0
in. (51 mm) dia. with a cap glued to one end is perfect. Place an oxygen service
contents scale sleeve (P/N GL50-9C43) over the sight tube.
2. Support the gauge assembly by holding the base of the indicator tube. Care must be
taken to prevent interference with the spring action or from misaligning the scale sleeve.
Immerse teh aluminum float rod below the water level as illustrated. The gauge assem-
bly must be held vertically and the rod must not touch the side or bottom of the tube.
The yellow level indicator of the gauge should indicate a full level reading with the
oxygen scale.
If the gauge fails to indicate a full liquid level, the assemlby is to be removed from the
water, calibrated and retested.
To change calibration, loosen locking nut away from the brass calibration nut, the exposed
portion of rod becomes longer and the gauge yellow band will be lowered.
To raise the yellow band, turn rod counterclockwise. The exposed portion becomes shorter.
Once you have adjusted calibration, recheck for proper setting. (See illustration.) After
proper setting has been obtained, lock down nut against calibration nut.
3. Once the gauge assembly has been calibrated and to read full in water, it must be
verified that it reads empy when the aluminum floating rod is suspended in air. The
yellow indicator must be as cloase to the bottom as possible (inner rod will be firmly
bottomed out.)
If calibration is required to make the gauge read empty in air, it must be rechecked in
water.
4. After calibration, you will need to follow contents gauge installation to reinsert gauge.
Be sure to dry the assembly before reinserting into the cylinder to prevent ice build-up
that could restrict movement or catch on teh guide ring inside the cylinder.
