Installation position
VEGAPULS 63 • Foundation Fieldbus
1. Make sure the number of flange screws corresponds to the num-
ber of flange holes
2. Use disc springs in addition to the flange screws for fastening the
flange
3. Tighten the screws steadily with the torque specified in the techni-
cal data
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 maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup on
the vessel wall is expected. In such cases, we recommend repeating
the false signal suppression at a later date with existing buildup.

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