Liquiphant FTL31 IO-Link
5.1.5 Weld-in adapter with leakage hole
If installed horizontally, make sure that the leakage hole is pointing down. This allows leaks
to be detected as quickly as possible.
5.1.6 Marking
The marking indicates the position of the tuning fork. If installed horizontally in vessels, the
marking is face up.
The marking is either a material specification (e.g. 316L) or a type of thread (e.g. G ½") and is
located:
• On the hexagonal bolt of the process adapter
• On the nameplate
• On the weld-in adapter
