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.
Refer to 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.
Prepare the process gas sampling line connecting the device
1. 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!(Pressure regulators and
shut-off valves are not equipment parts and are not included in the delivery;
make sure you use types that comply with the specifications and standards)
2. 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.
3. Carefully open the shut-off valves to create a permitted gas flow above the oper-
ating conditions. Then flush for around 30 to 45 seconds to clean the pipeline
system. For very long lines you must extend this time accordingly.
4. Close the line shut-off again. Set the process gas pressure to a valid value, do
not exceed the maximum pressure! (The exact pressure will be set later).
5. The pipeline is now ready for connection to the device. Prevent the penetration
of dirt and moisture if the connection is not made immediately.
6. Remove the protection (sealing stopper/ sealing screws) from the (PG) device
inlet and connect the gas line for the process gas. Observe the information in
section 5.4.1 Fluid interfaces
➪
7. Carefully open all the shut-off valves in the gas path so that the gas is present
at the device inlet
8. Check the tightness of the process gas path from the source to the device. Refer
to the section.
