2.3 Installing the Promag E sensor
"
Caution!
• The plates mounted on the two sensor flanges protect the PTFE which is turned over the
flanges and, consequently, should not be removed until immediately prior to mounting the
sensor.
• The protective plates must always remain mounted while the device is in storage.
• Make sure that the lining at the flange is not damaged or removed.
2.3.1 Seals
Comply with the following instructions when installing seals:
• No seals are required for PFTE measuring tube lining.
• For DIN flanges, only use seals to DIN EN 1514-1.
• Make sure that the mounted seals do not protrude into the piping cross-section.

Caution!
Risk of short circuit! Do not use electrically conductive sealing compounds such as graphite! An
electrically conductive layer could form on the inside of the measuring tube and short-circuit the
measuring signal.
2.3.2 Ground cable
If necessary, special ground cables can be ordered as accessories for potential equalization.
2.3.3 Screw tightening torques (Promag E)
Please note the following:
• The tightening torques listed below are for lubricated threads only.
• Always tighten the screws uniformly and in diagonally opposite sequence.
• Overtightening the screws will deform the sealing faces or damage the seals.
• The tightening torques listed below apply only to pipes not subjected to tensile stress.
