4.5 Socket extensions
The ultrasonic sensors require a min. dis-
tance to the liquid or solid product. Take the
min. distance into account in your planning. In
some situations, it is possible to reach the
required min. distance, and hence the de-
sired filling height, with a socket extension.
However, the socket extension increases the
noise level of the ultrasonic signal at the ex-
tension outlet and can interfere with the
measurement. Only use a socket extension if
all other possibilities have to be excluded.
Carry out the extension as shown in the fol-
lowing illustration.
Socket extensions in liquids
Chamfer and deburr the socket carefully and
make sure it has a smooth inner surface. The
socket should not protrude into the meas-
ured product, in case buildup can form on
the socket through pollution or product resi-
dues.

products (illustration: VEGASON 53)
The socket diameter should be as large and
the socket length as small as possible. Make
sure that the socket outlet is burr-free to
minimise false echoes.
Mounting and installation
Material heaps
Large material heaps are best detected with
several instruments, which can be mounted
on e.g. traverse cranes. For this type of ap-
plication, it is advantageous to orient the
sensor directly toward the solid surface.
