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 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 extensions 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.
Socket piece should not penetrate into adhesive
products (VEGASON 53)
Socket extension with solids
For solids provide a conical socket extension
with an angle of at least 15
°
… 20
°
.
Socket extension with solids
Choose a possibly large socket diameter
and a possibly small socket length, ensure
that the socket opening is burr free to mini-
mize false echoes.
For measurements in products which do not
cause any build-up, the socket extension in
form of a meas. pipe can be submerged
permanently into the measured product. The
ultrasonic measurement is then only carried
out in the meas. pipe without being interfered
by vessel installations (see page 28 "Pump
shaft").
