Brackets

NOTICE
Potential damage to the device!
Improper support for the device may result in a deformed
housing and damage to internal magnetic coils.
Place the supports at the edge of the sensor housing (see
arrows in Figure 5).
Figure 5: Support for nominal diameters larger than DN 400
Devices with nominal diameters larger than DN 400 must be
mounted on a sufficiently strong foundation with support.

Gaskets

The following points must be observed when installing gaskets:
To achieve the best results, make sure that the gaskets
and meter tube fit concentrically.
To make sure that the flow profile is not distorted, the
gaskets may not intrude in the piping cross-section.
The use of graphite with the flange or process connection
gaskets is prohibited. This is because, in some instances,
an electrically conductive coating may form on the inside
of the meter tube.
Devices with hard rubber or soft rubber liner
Devices with a hard / soft rubber liner always require
additional gaskets
ABB recommends using gaskets made from rubber or
rubber-like sealing materials
When selecting the gaskets, make sure that the tightening
torques specified in chapter Torque information on page 82
are not up-scaled.
Devices with a PTFE, PFA or ETFE liner
In principle, devices with a PTFE, PFA or ETFE liner do not
require additional gaskets.
