10.5 Input of the sound path number
10.6 Transducer distance
The transducer distance is the distance between the inner edges of the transducers (see section 3.3 and Fig. 10.1)
In case of a measurement in diagonal arrangement on very small pipes, a negative transducer distance is possible.
10.6.1 Fine adjustment of the transducer distance
In case of large deviations, check if the entered parameters are correct or repeat the measurement at a different point on
the pipe.
Repeat the steps for all channels on which a measurement is made. The measurement will be started automatically after-
wards.
A number of sound paths is recommended according to the connected transducers and the
entered parameters. Change the value, if necessary. Press ENTER.
For the determination of the number of sound paths, see section 3.3.
A value for the transducer distance is recommended. Fix the transducers (see chapter 10).
Adjust the transducer distance.
Press ENTER.
A – measuring channel
Reflec – reflection arrangement
Diagon – diagonal arrangement
Note! The accuracy of the recommended transducer distance depends on the accuracy of the entered pipe
and fluid parameters.
If the displayed transducer distance is adjusted, press ENTER.
The measuring run for the positioning of the transducers is started.
The amplitude of the received signal is displayed by the bar graph S=.
If the LED of the measuring channel lights green, the signal is sufficient for a measurement.
If the LED of the measuring channel lights red, the signal is not sufficient for a measure-
ment.
• Shift a transducer slightly within the range of the recommended transducer distance.
The following quantities can be displayed in the upper line by pressing key and in the
lower line by pressing key :
• ■<>■=: 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 measurement, Q= UNDEF will be displayed.
After the precise transducer positioning, the recommended transducer distance is dis-
played again.
Enter the actual (precise) transducer distance. Press ENTER.
