Installation
3.4 Install sensor
The SONATAX sc is intended for installation with a tank edge
attachment. For more information, refer to the installation
instructions of the tank edge attachment.
Note: Do not begin with the installation of the tank edge attachment before
the installation location is determined (refer to
Section 3.4.1 ).

3.4.1 Select the measurement location and pre-set the device
In the determination of the sludge level over the duration of an
ultrasonic echo, the entire space between the probe on the water
surface and the tank bottom is required for the measurement. As
solid bodies in this area disrupt the measurements, special
attention is required in the selection of the measurement location.
In the following, it is explained how the suitability of a possible
measurement location can be tested. The tank depth should be
known here.
A suitable measurement location must be found depending on tank
type. The graphics that follow show typical examples for a round
tank and a rectangular tank. The point (1) in
Figure 7 and Figure 8
is a suitable measurement location.
