4.1 General instructions
When (un)installing pressurizable equipment onto the gas extraction device or the gas
preparation system (SGA), the working pressure is to be reduced to the level of the ambient
atmosphere.
The analyzer is joined by eight threaded bolts that guarantee rupture resistance up to 8300
bar.
Electrical installation of the CP M is to be carried out in accordance with Appendix A.
The sample gas release outlets (Appendix E, position 13 and 14) must be separately
connected to a collector that releases this gas to the atmosphere. The collector must have a
minimum inner diameter of 20mm.
4.2 Sample extraction site requirements:
The CP 2M’s sample extraction device must be located on a straight length of pipe. There
must be at least five pipe-diameter widths of straight pipe upstream of the extraction site and
three pipe-diameter widths downstream of the extraction site. There must not be any
bottlenecks of obstructions within this section.
The gas sample must be taken from near the center of the gas flow.
A pipe for venting sample gas to the atmosphere must be present to ensure a constant flow
rate through the measuring chamber.
