Mounting and installation
4.4 Socket extensions
The ultrasonic sensor requires a min. dis-
tance to the product or solid. Note this min.
distance in your planning.
In exceptions it is possible to reach the re-
quired min. distance and hence the desired
filling height with a socket piece. However,
the socket piece increases the noise level of
the ultrasonic signal and can interfere with the
measurement. Only provide the socket ex-
tension when there is no other possibility, and
carry out the extension as shown in the fol-
lowing figure.
Socket extension with liquids
Chamfer the socket carefully and ensure a
smooth inner side of the socket. The socket
should not protrude into the measured prod-
uct when pollution or measured product
could stick to the socket.
For measurements in products which do not
cause any build-up, the socket extension, in
form of a meas. pipe, can be permanently
submerged into the measured product. The
ultrasonic mesurement is then only carried
out in the meas. pipe without being interfered
with by vessel installations (see page 28
"Pump shaft“).
Socket piece should not be submerged into the
adhesive product (figure: VEGASON 53)

Choose as large a socket diameter as possi-
ble and as small a socket length as possible.
Ensure that the socket opening is burr free to
minimise false echoes.
