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:
• Observe in any case the necessary screw tightening torques on Page 35
• The mounting of additional ground disks is described on Page 33.

Seals
Comply with the following instructions when installing seals:
• Measuring tube linings with PFA or PTFE → No seals are required.
• In case you use seals with 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 15…600)
If necessary, a special ground cable for potential equalisation can be ordered as an
accessory (see Page 97). Detailled assembly instructions → Page 57
