C2.4 Measuring
Mode
This menu item is set by default to "Direct
Measuring" to measure the level of most
tank contents. The device uses the largest
radar signal to monitor level. If it is
possible there will be an interference
signal in the measurement zone that is
larger than the level signal, select "Direct
Plus" mode. If you select "Direct Plus"
mode, the device locks on the level signal
and monitors changes in level. If the device
then finds larger reflections in the silo, it
will only monitor the largest signal in a
small search zone around the first
reflection found and ignore all other
reflections. The interference signal must
not be near to the level signal. Refer also to
"Measuring principle" on page 123.

C2.5 Overfill
Detection
If this function is in operation, the device
will monitor the level even if it is in the
blocking distance. The output shown on the
display screen stays fixed at the blocking
distance, but an error message will warn
the user that the tank is too full.

C2.6 Overfill
Threshold
If you have set menu item C2.5 Overfill
Detection to "Enabled", this menu item will
be available. If the device cannot easily
measure in the blocking distance (see
menu item C1.5), then you can change the
overfill threshold. This value is a
percentage of the radar signal amplitude.
To enter the correct value, we recommend
that you speak or write to your supplier.

C2.7 Mult. Refl.
Enable
Multiple reflections will cause the device to
display smaller level readings. Installation
of the device on a manhole or at the centre
of a dome roof, and high dielectric products
(
ε
r >5) can cause multiple reflections. A
very calm surface or a tank with a small
convex or flat roof can also cause multiple
reflections.
If this function is in operation, the device
looks for the first signal peak below the
process connection. This signal peak is
then used to measure the level of the tank
contents. If this function is not in operation,
the device looks for the largest signal
below the process connection.
