Fig. 2: Reference plane
1-4 VEGAPULS 42 with thread: The reference plane is the sealing surface at the
bottom of the hexagon.
5-6 VEGAPULS 42 with hygienic fitting: The reference plane is the highest
contact point between sensor process fitting and welded socket.
When mounting the device, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the device is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can be suppressed by an appropriate adjustment (see chapter
"
Set up
").
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
device in the centre of the vessel, as measurement is then possible
down to the bottom.
