The sample system should be located so that it is able to deliver a
sample at a flow rate of 1,000 ±150 cc/min. For best results, mount
the sample system as close as possible to the CGA 351. An ideal
location would be on the same panel, just below the analyzer. If there
are questions, consult with an applications engineer at GE
Infrastructure Sensing.
See Figure 2-1 on page 2-9, and complete the following steps to
connect the sample system to the analyzer:
1. Using 6mm stainless steel tubing (or ¼" stainless steel tubing with
adaptors), connect the gas source from the sample system to the
Swagelok fitting on the flow control valve at the inlet port on the
analyzer.
2. Using 6mm stainless steel tubing (or ¼" stainless steel tubing with
adaptors), connect the Swagelok outlet fitting at the top of the
flowmeter on the analyzer to the gas discharge connection on the
sample system.
Note: If desired, a suitable sample system may be ordered directly
from the factory. The sample system would be supplied fully
assembled on a flat plate with four (4) mounting holes.
