FULL VIEW CONTENTS GAUGE MAINTENANCE
The contents 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 gauge is assembled, a level indicator ring is magnetically coupled to the top of a
float rod 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.
If the level indicator does not move when container is filled, it may indicate that the
magnetic field between the level indicator and the gauge has been uncoupled. The
level indicator should recouple itself as the container is emptied. However, a re-
engagement tool (ring) is available to correct the problem immediately. To reestablish
the correct relationship, slip the re-engagement ring over the contents gauge and its
protective cover. The magnetic field of this tool will allow you to lift the yellow level
indicator until it recouples with the magnetic field on the gauge rod.
Removing the Full View Contents Gauge
1. Vent all pressure from the container.
2. Remove the protective cover by removing three bolts from the base cover.
3. Unscrew the gauge body using a wrench on hex fittings at base of the indicator.
4. Lift the entire gauge assembly free of the container. The gauge assembly is long
and my be very cold. Gloves should be used to protect your skin.
Calibration Procedure for Liquid Level Contents Gauge
1. You will need a column of water approximately 4-ft. (1.2 m) tall. A clear plastic
tube 2.0-in. (51 mm) with a cap glued to one end of perfect.
2. Support the gauge assembly by holding the base of the indicator tube. Care must
be taken to prevent interference with the spring action. Partially immerse the
aluminum float road in the water. The water level should be 3.0 in. (76 mm) below
the top of the rod as illustrated. The gauge assembly 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 reading with the scale.
If the gauge fails to indicate a full liquid level, the assembly is to be removed from the
water, calibrated and retested.
To change calibration, loosen locking nut away from brass calibration nut and turn the
threaded rod with respect to the calibration nut.
WARNING:
Cold surfaces should never be handled
with bare skin. Use gloves and other
protective clothing when performing
this procedure.
