5.3.2 Connecting gas lines (general)
The recognized rules of technology for dealing with pure gases must be observed during all work
as described. Surfaces which come into contact with gas must be free of grease, oil, solvents and
other contaminants.
All gases must not be altered or corrupted during transport from their
source (pipeline / cylinder) to the measurement device.
Install the gas tubes up to the Q2. Do so according to the piping diagram of
the plant operator.
Make sure that each line or each gas path contains the required safety and shut-off devices.
All lines must be kept as short as possible. Use only dense, clean gas lines.
Take measures to prevent dirt and/or moisture reaching the device and
distorting the measurements or causing damage. Stainless steel fulfills
these properties. Fittings and pipe joints with small dead volumes are
preferred.
The mixing of tube fittings parts of various brands for the production of
gas-related equipment connecting is prohibited.
Before connecting to the Q2, the line must be flushed for 30 seconds with
gas to make sure the line is clean. The purge gas must be professionally
and safely discharged.
5.3.3 Preparing the process gas
The process gas is retrieved from the process line (pipeline). The sampling device should have
temperature compensation and pressure control. It should be located as close as possible to the
Q2.
The particle filter inside the process gas inlet of the Q2 serves the
protection of the device and is not a substitute for a primary filter system, it
must not be used for these purposes. A primary filter system is required in
any case, if the gas specifications (see chapter 10) are not met.
Volume and pressure of the sample line influence the total response time of
the system and, thus, the delay between the moment of sampling and the
measurement result.
Additional shut-off valves, pressure reducers, filters, gas dryers, etc. may
have to be provided so that the sampled process gas meets the required
specifications when entering the device.
