Level Gauge
The liquid level gauge is a float and spring that approximates
the amount of product in the container. The design of this
gauge makes it possible to use the same float and spring for
nitrogen, oxygen and argon. However, the liquid level decal
must be changed for each product. The decals are marked N
for nitrogen, O for oxygen and A for argon. If the gauge is
malfunctioning it should be removed from the container and
repaired. The following procedure should be followed (see
Figure 23).
1
Open the vent valve and release any pressure that is in
the container
2
Remove the nylon sight gauge protector (Item 3).
3
Unscrew and remove the sight gauge (Item 5).
4
Replace any damaged parts, stretched springs or bent
floats.
5 Adjust the sight gauge assembly as follows:
a
Hold the sight gauge assembly allowing the float to
hang freely
b
The top of the indicator’s white tip should be in the
empty zone.
c
Loosen the spring retainer (Item 8) and adjust the
spring up and down the float rod until the indicator
hangs freely in the right location. Tighten the spring
retainer
d
Replace the o-ring/gasket (Item 7).
e
Insert the float and sight gauge assembly into the
container. Make sure that it engages in the float
guide located approximately 21 inches into the
container
f
Tighten the sight gauge to 1/4 turn past hand tight
(150 in/lbs) and replace the protector.
Warning! Remove all pressure from
the cylinder before repairing
the liquid level gauge. Gloves
should be worn when handling
the float rod to prevent burns.
Warning! DO NOT clean the plastic sight
gauge with solvent cleaners.
