3-6 Performance Verification
Refer to Figure 6-1 and 6-2 to identify parts with bold number references.
PROCEDURE
1. Fill the Companion 1000/T Portable with liquid oxygen. Allow approximately one
hour for the system pressure to stabilize. Verify that the primary relief valve is
venting and that the system pressure is 20.5 to 24.0 psig (141 to 165 kPa).

2. Attach the / -in. vinyl tubing (P/N B-778214-00) between the oxygen outlet
16
barbed fitting 9 and the appropriate flowmeter.
3. At each flow setting, check the flow control valve 30.
• Flow values listed in Table 3-1 were produced in ambient conditions of 70°F (21°C)
and 29.4 in. Hg (74 mm Hg). Any deviation from these conditions will affect the flow
results.
• Data listed in Table 3-1 is based on flowmeters with full-scale accuracy of 1% for flow
ranges of 0.10 to 1.20 L/min., 0.70 to 7.08 L/min., and 1.0 to 21.0 L/min. Using
flowmeters with specifications other than those listed may produce different results.
• Data listed in Table 3-1 is based on an operating pressure range of 20.5 to
24 psig (141 to 166 kPa). If flow measurements are out of specification, check the
pressure in the unit. A combination of high or low pressure and the tolerance of the
particular flowmeter you are using can result in inaccurate readings.
