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.
