component. By turning the instrument in the connection flange or
mounting boss, the polarisation can be used to reduce the effects of
false echoes.
The position of the polarisation plane is marked on the process fitting
of the instrument.

When mounting the VEGAPULS 63, keep a distance of at least
200 mm (7.874 in) to the vessel wall. If the sensor is installed in the
center of dished or round vessel tops, multiple echoes can arise.
These can, however, be suppressed by an appropriate adjustment
(see chapter "Setup").
If you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo stor-
age later with existing buildup.

In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.
