Mounting the seals
! CAUTION
An electrically conductive layer could form on the inside of the measuring tube!
Risk of measuring signal short circuit.
‣
Do not use electrically conductive sealing compounds such as graphite.
Comply with the following instructions when installing seals:
• When mounting the process connections, make sure that the seals concerned are clean and
centered correctly.
• For DIN flanges: only use seals according to DIN EN 1514-1.
• For "PFA" lining: additional seals are always required.
• For "PTFE" lining: generally additional seals are not required.
