Mounting and installation
Therefore, in practical application, the trans-
ducer has to be oriented so that lowest pos-
sible false echo signal strength is achieved.
Only giving attention to the size of the useful
echo is usually not adequate under difficult
measuring conditions. In most cases, a low
false echo level enables the sensor to reliably
pick up the useful echo. With the adjustment
software VVO on the PC, you can view the
echo image (see chapter "6.2 Adjustment
with VVO – Sensor optimisation – Echo
curve“).

On flat vessels, mounting is usually done on
a very short DIN socket piece. Reference
plane for flange versions is the instrument
flange. The transducer should protrude out
of the flange tube.

A mounting location directly on the vessel top
is ideal. A round opening in the vessel top is
sufficient to fasten the VEGASON 53 sensor
with a compression flange.
