2.3 Installing the Promag L sensor
"
Caution!
• The protective covers mounted on the two sensor flanges (DN 50…300) are used to hold the
lap joint flanges in place and to protect the PTFE liner during transportation. Consequently,
do not remove these covers until immediately before the sensor is installed in the pipe.
• The protective plates must always remain mounted while the device is in storage.
• Make sure that the lining at the flange is not damaged or removed.
2.3.1 Seals
Comply with the following instructions when installing seals:
• Hard rubber lining → additional seals are always required!
• Polyurethane lining → no
seals are required.
• No seals are required for PFTE measuring tube lining.
• For DIN flanges, only use seals to DIN EN 1514-1.
• Make sure that the mounted seals do not protrude into the piping cross-section.

Caution!
Risk of short circuit!
Do not use electrically conductive sealing compounds such as graphite! An electrically
conductive layer could form on the inside of the measuring tube and short-circuit the measuring
signal.
2.3.2 Ground cable
If necessary, special ground cables can be ordered as accessories for potential equalization.
