On the left, you see the constructional fea-
tures of a measuring pipe as exemplified by
a radar sensor with a DN 100 flange.
Radar sensors with flanges of DN 80,
DN 100 and DN 150 are equipped with a
horn antenna. Instead of the welding neck
flange also a smooth welding flange can be
used on the sensor side of these sensors.
In agitated products, fasten the measuring
pipe to the vessel bottom. Provide additional
fastenings for longer measuring pipes.
With the deflector on the measuring pipe end,
the radar signals are reflected away from the
vessel bottom. This assures that, in nearly
empty vessel and products with low dielec-
tric constants, the medium is detected, not
the vessel bottom. Products with low dielec-
tric constant are penetrated by the signals
and, when the product level is low, allow the
vessel bottom to deliver stronger echoes
than the product surface.
Due to the deflector, the useful signal, and
thus the measurement value, can be clearly
detected in a nearly empty vessel and the
0 % level can be reliably detected.
