3.3.2 Installing the Promag P sensor

Caution:
• The protective covers mounted on the two sensor flanges guard the Teflon (PTFE) lin-
ing, which is turned over the flanges. Consequently, do not remove these covers until
immediately before the sensor is installed in the pipe.
• The covers must remain in place while the device is in storage.
• Make sure that the lining is not damaged or removed from the flanges.

Note:
Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by
the customer.
The sensor is designed for installation between the two piping flanges. Always tighten
all threaded fasteners to the specified torques

Seals
Comply with the following instructions when installing seals:
• Measuring tube linings with PFA or PTFE → No seals are required.
• 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.
Grounding cable (DN 15...600)
If necessary, the special grounding cable for potential equalisation can be ordered as
an accessory (see Page 111). Detailled assembly instructions
