Mounting the sensor

WARNING
L
Danger due to improper process sealing!
‣
Ensure that the inside diameters of the gaskets are greater than or equal to that of the
process connections and piping.
‣
Ensure that the seals are clean and undamaged.
‣
Secure the seals correctly.
1. Ensure that the direction of the arrow on the sensor matches the flow direction of
the medium.
2. To ensure compliance with device specifications, install the measuring device
between the pipe flanges in a way that it is centered in the measurement section.
3. If using ground disks, comply with the Installation Instructions provided.
4. Observe the necessary screw tightening torques →  33.
5. Install the measuring device or turn the transmitter housing so that the cable entries
do not point upwards.

Mounting the seals
CAUTION
L
An electrically conductive layer could form on the inside of the measuring tube!
Risk of measuring signal short circuit.
‣
Do not use electrically conductive sealing compounds such as graphite.
Comply with the following instructions when installing seals:
1. Make sure that the seals do not protrude into the piping cross-section.
2. For DIN flanges: only use seals according to DIN EN 1514-1.
3. For a "hard rubber" liner: additional seals are always required.
4. For a "polyurethane" liner: additional seals are generally not required.
Mounting the ground cable/ground disks
Comply with the information on potential equalization and detailed mounting instructions
for the use of ground cables/ground disks →  54.
Screw tightening torques
Note the following points:
• The screw tightening torques listed below apply only to lubricated threads and to pipes
not subjected to tensile stress.
• Tighten the screws uniformly and in diagonally opposite sequence.
• Overtightening the screws will deform the sealing surface or damage the seal.
• In the case of linings made of hard rubber, seals made of rubber or rubber-like materials
are recommended..
