Installing the Promag S sensor
Note!
Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the customer.
Caution!
• The protective covers mounted on the two sensor flanges guard the PTFE lining, which is turned
over the flanges. Consequently, do not remove these protection plates until immediately before
the sensor is installed in the pipe.
• Protection plates must remain in place while the device is in storage.
• Make sure that the lining is not damaged or removed from the flanges.
The sensor is designed for installation between the two piping flanges:
• It is essential that you observe the necessary torques on → Page 26 ff.
• Information on the installation of additional ground disks → Page 25

Seals
Comply with the following instructions when installing seals:
• Hard rubber lining → additional seals are always necessary!
• Natural rubber lining → Seals may not be used.
• PFA, PTFE or PU (polyurethane) lining → No seals are required.
• 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.
