Seals
Comply with the following instructions when installing seals:
• Hard rubber lining → additional seals are always necessary!
• Polyurethane lining → additional seals are recommended
• For DIN flanges, use only seals according to DIN 2690.
• Make sure that the seals do not protrude into the piping cross-section.
Caution!
Risk of short-circuit! Do not use electrically conductive sealing compound such as
graphite! An electrically conductive layer could form on the inside of the measuring tube
and short-circuit the measuring signal.
Ground cable (DN 25...600)
If necessary, special ground cables for potential equalisation can be ordered as
accessories for potential equalisation (see Page 64). Detailed mounting instructions →
