5-4.2.13 WEIGHING FM-200 CYLINDERS
Weigh 10 through 900 lb. FM-200 cylinders as follows:
WARNING
!
Install a protection cap on the FM-200 cylinder
valve actuation port and safety cap on the
cylinder valve outlet port.
Disconnect all cylinder control heads,
discharge hoses, and flexible pilot hoses to
prevent accidental system discharge.
1. Remove the cylinder as instructed in Paragraph 5-7.
2. Place the cylinder on a scale.
3. Record the weight and date on a record card and at-
tach it to the cylinder. The gross weight and tare (empty)
weight are metal stamped on the FM-200 cylinder valve
label. Therefore, subtract tare weight from the gross
weight to determine net weight of the original charge.
Then, subtract tare weight from the scale reading to
determine net weight of the FM-200 agent remaining
in the cylinder. If the recorded agent net weight is less
than 95% of original charge net weight, replace the cyl-
inder with a fully charged FM-200 cylinder (recharging
the cylinders is explained in Paragraph 6-3).
4. Reinstall the cylinder (see Paragraph 5-8 for reinstalla-
tion instructions).
5-4.2.14 CYLINDERS EQUIPPED WITH A FLEXIBLE
TAPE LIQUID LEVEL INDICATOR
The following procedure explains how to determine the
FM-200 weight of 125, 200, 350, 600 and 900 lb. cylinders
equipped with a flexible tape liquid level indicator. This pro-
cedure can be performed without removing the FM-200 cyl-
inders from the system.
1. Remove the protective cap to expose the tape.
2. Raise the flexible tape slowly until it latches.
3. Note the reading at the point where the tape emerges
from the fitting.
CAUTION
!
Take care to not pull the flexible tape upwards
after it latches to ensure an accurate reading.
4. To determine the final, more precise reading, repeat
the above procedure. About two inches before the tape
should latch, raise the tape very slowly until it latches.
5. While supporting the weight of the tape, record the liq-
uid level measurement.

6. Check the ambient temperature where the FM-200 cyl-
inders are stored and record the temperature.
7. Refer to the appropriate calibration charts (see Figures
5-2 through 5-7) and locate the level reading on the
vertical axis (labeled Flexible Tape Reading). Trace hori-
zontally to the right to the appropriate temperature line.
Read the weight of FM-200 from the scale at the bot-
tom of the chart. Record the weight and date on the
record tag attached to the cylinder.
8. After taking the reading, carefully push the tape down
into the liquid level housing. Replace the protective cap.
Note: If the weight measured by the liquid level indicator
indicates the cylinder should be recharged, we rec-
ommend the cylinder first be removed from ser-
vice and the weight loss verified using a weigh scale
before recharging.
All FM-200 cylinders must be filled or recharged by weight
using a platform scale or equivalent. If weight loss is more
than 5% of the FM-200 charge, the unit must be recharged.
