Adjustment of the transducer distance
The recommended transducer distance will be displayed.
• Mount the transducers on the pipe adjusting the transducer distance.
• Press ENTER.
Reflec – reflection arrangement
Diagon – diagonal arrangement
The transducer distance is measured between the inner edges of the transducers.
In case of a measurement in diagonal mode on very small pipes, a negative transducer
distance is possible.
The diagnostics window is displayed, see Fig. 9.1.
Fine adjustment of the transducer distance
• If the displayed transducer distance is adjusted, press ENTER.
The measuring run for the positioning of the transducers is started.
The bar graph
S= shows the amplitude of the received signal, see Fig. 9.1.
• Shift one of the transducers slightly within the range of the recommended transducer
distance until the bar graph reaches the max. length (6 squares).
The following quantities can be displayed in the upper line by pressing key and in the
lower line by pressing key , see Fig. 9.2:

transducer distance
• time : transit time of the measuring signal in μs
• S : signal amplitude
• Q : signal quality, bar graph has to have max. length
If the signal is not sufficient for a measurement,
Q= UNDEF
will be displayed.

Notice!
The accuracy of the recommended transducer distance depends on the accuracy of
the entered pipe and fluid parameters.
