GASLAB Q2 AFTER DELIVERY AND AT THE PLACE OF USE
Information for general use
Rev. M / 73023639
5.3.3. Connect the process gas line
Prerequisite: The process gas from the process line (pipeline) is provided according to specification
via the tapping equipment with temperature equalization system and pressure regulator.
11.3 List of suitable gases and calibration gases
For this purpose, additional shut-off devices, further pressure reductions, filter system, gas dryer,
etc. were installed on site and provided in the pipeline.
If an automatic verification measurement is to be carried out via the process gas inlet, an additional
automated 3-way valve must be installed in the gas flow.
Action: Prepare the process gas sampling line connecting the device
Ensure that the shut-off valve in the process gas pipeline is closed!
If there is a pressure regulator, it must be set to its lowest setting!
Check whether the pressure and other parameters are correct and connect the end of
the line intended for the device connection to the vent gas properly using a hose.
Carefully open the shut-off valves to create a permitted gas flow above the operating
conditions. Then flush for around 30 seconds to clean the pipeline system. For very
long lines you must extend this time accordingly.
Close the line shut-off again. Set to a process gas pressure between
0.15 MPag ≙ 21.76psig ≙ 1.5barg and maximum 0.3MPag ≙ 43.51psig ≙ 3barg.
(The exact pressure will be set later).
The pipeline is now ready for connection to GasLab Q2. Prevent the penetration of dirt
and moisture if the connection is not made immediately.
Remove the protection (sealing stopper/ sealing screws) from the (PG) device inlet
and connect the gas line for the process gas as shown in Figure 5.2.
Carefully open all the shut-off valves in the gas path so that the gas is present at the
device inlet
Check the tightness of the process gas path from the source to the device
