5. Assembly and Disassembly
5.1 Safety and Assembly Instructions
Caution – danger zone warning!
Please pay attention to the following prior to installation and commissioning:
• Check the measuring system for visible external and internal damage.
• Check the process housing inside for residues.
• Check the current piping status (pressure, temperature, medium).
Please pay attention to the following if malfunctions occur and prior to
disassembly:
• Check the current piping status (pressure, temperature, medium).
Risk of injuries!
Risk of burns!
If the process housing is integrated in a piping system in which the media
can reach a temperature of more than 50°C, the surface temperature can also reach
this value.
Risk of scalding, chemical burns!
If the process housing is integrated in a piping system that has not been fully emptied
or is still pressurised, there is a risk of scalding and other personal injuries.
Caution – functional impairment or material damage!
Installation instructions:
• Measuring system for welding in must be disassembled first. The process housing
is then welded into the piping system free of tension.
• Remove welding residue from the piping system.
• The welding work (TIG, welding gas) should only be carried out by qualified
welders
(EN 287-1).
• There must be sufficient free space around the measuring system for subsequent
assembly and maintenance tasks.
