2.2 Operating Procedure
To operate the MG-101, refer to Figure 5 below and Figure 6 on page 9 to complete the following steps:
1. Fully close all four rotameter valves by turning them clockwise.
2. Set the WET/DRY selector valve to DRY .
CAUTION! This valve must always be in the WET position before the “WET GAS” flowmeter valve is opened,
and it must remain in the DRY position until the “WET GAS” flowmeter valve is closed.
3. Set the pressure regulator on the nitrogen gas inlet line to approximately 55 psig.
4. Make sure the vent valve at the top of the front panel is fully open.
5. Fully open the valve on the
WET GAS DILUTED
rotameter.
Note:
The rotameters are dual-range, floating-ball types, each having both a steel ball and a glass ball. When
reading the rotameters be careful to watch either the steel ball or the glass ball (see Figure 4 below) as
directed (numbers in tables are followed by an
S
or a
G
to designate the ball material).
