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 acc. 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.
