32.1.3 Path Arrangement
Depending on the channel profile set either all or only a part of the path arrangements below
are available:
• Diametral \ (circular pipes only)
• Diametral V (circular pipes only)
• Diametral VV (circular pipes only)
• Chordal \
• Chordal V
• Chordal VV
• Chordal X
• Chordal XX
• Chordal XXXX
32.1.4 Number of Paths
A maximum of four paths can be connected directly. The number of paths can be increased up
to 32 by connecting up to four extension modules.
Set the number of paths by using the arrow buttons. The number is shown in the text field
between both arrows.

32.1.5 SonicPro T
The checkbox here must be ticked as soon as a SonicPro T overvoltage protection element is
to be installed between sensor and transmitter or between sensor and NFE extension module.
When connecting the sensors/the system the service technician needs to check in menu
>Application< / >Diagnostics< / >v-Paths< whether a resistor must be connected to the over-
voltage protection element and if so, which colour the resistor needs to have (blue or red).

32.1.6 Medium
Select between “Water” and “User defined”. The “Water” option features fixed properties, while
“User defined” requires specifying medium properties such as speed of sound and damping
and density when setting parameters.
