r = Radius of pipe including wall thickness
(“outer radius”)
Example: Radius (outer) = 250mm -> U =
2*3.1415*250mm/2 = 785.4mm
6. Position the zero line of the measuring tape onto the
center of the second cross hair drawn on the pipe (at
same level as first transducer). Measure the previously
calculated distance (half circumference). You should
now have located the precise position opposite to the
first transducer. Draw a third line at this position.

Transducer
7. Mount the second transducer. Its face is positioned
on the axis of the second line drawn. The
transducer
face
is centered onto the third cross hair. The trans-
ducers are now mounted precisely opposite to each
other and are prepared for measuring in Z-mode.

EDIT PARAMETERS
Edit system parameters using the complete setup menu.
However, this method is less convenient, as it does not
offer a step-by-step guide to setting up the parameters. It
is therefore recommended to use the main menu only in
situations that require editing of an individual parameter.
Editing the parameters includes access to piping, fluid
and dialogs for selecting the ultrasonic transducer and
mounting mode.
If you only want to change the mounting mode from V to
Z, simply select “Transducer parameters” and change it
without having to run a complete “Quick Setup” session.
This document provides only a brief overview of how
to setup the parameters and main menu in the form of
structure diagrams that help identify the functions grouped
in the respective menu.
Navigate to the main menu:
In the primary measuring window “Flow 1”: Select “Setup”
-> “CMPL. SETUP”
Select the parameters to edit, for example, “Pipe Setup,”
“Fluid Setup,” or “Transducer Setup.”
