If there are good reflection conditions (liquid
medium, no vessel installations), we recom-
mend locating the sensor where there is no
vessel wall within the inner emission cone. For
products in less favourable reflection envi-
ronments, it is a good idea to also keep the
outer emission cone free of interfering instal-
lations. Note chapter "4.1 General installation
instructions“.
Foam generation
Thick, dense and creamy foam on the prod-
uct can cause incorrect measurements. Take
measures to avoid foam, measure in a by-
pass tube or use another measuring technol-
ogy, e.g. capacitive meas. probes or
hydrostatic pressure transmitters.

Mounting and installation
Wrong orientation to the product
Weak measuring signals are generated if the
sensor is not directly pointed at the product
surface. Orient the sensor axis perpendicu-
larly to the product surface to achieve opti-
mum measuring results.
Sensor too close to the vessel wall
If the radar sensor is mounted too close to
the vessel wall, strong false echoes can be
caused. Buildup, rivets, screws or weld joints
superimpose their echoes onto the product
i.e. useful echo. Please ensure a sufficient
distance from the sensor to the vessel wall.
