Installing the Promag P sensor

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 covers until immediately before installing
the sensor.
• 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 → Page 38 ff.
• Information on the installation of additional ground disks → Page 36
Fig. 20: Installing the sensor
Seals
Comply with the following instructions when installing seals:
• Measuring tubes lined with PFA or PTFE → No seals are required.
• In case you use seals with DIN flanges, use only seals according to DIN EN 1514-1.
• 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 to 600)
If necessary, a special ground cable for potential matching can be ordered as an accessory
(→ Page 133 ff.). Detailed assembly instructions→ Page 66 ff.
