User Manual

When mounting the sensor, keep a distance of at least
200 mm (7.9 in) to the vessel wall. If the sensor is
installed in the center of concave or arched vessel tops,
multiple echoes can arise. These can, however, be
faded out by an appropriate adjustment (see Setup).
If this distance cannot be maintained, a false echo
storage should be carried out during setup. This applies
particularly if buildup on the vessel wall is expected. In
this case, we recommend repeating the false echo
storage later on with existing buildup.

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