19.2 Parameter Input
19.2.1 Parameter Input for the Wall Thickness Measurement
The sound speed of the pipe material has to be entered to measure the wall thickness.
Note! The wall thickness measurement mode will be activated as long as
the wall thickness probe is connected to the measuring channel.
Select Wall Thickness in Output Options\Physic.
Quant. for the measuring channel to which the wall thick-
ness probe is connected.
Select the pipe material in Parameter\Pipe Material.
If the material is not in the scroll list, select Other Mate-
rial.
Press ENTER.
A value for the longitudinal sound speed of the selected
material is recommended.
If Other Material has been selected, 0.0 m/s will be
displayed.
Enter the sound speed, if necessary. Press ENTER.
Note! The measurement can only be started if the entered sound speed is
> 0.
Compared to the flow measurement, the sound speed has a great,
approximately linear influence on the measuring result. If a sound
speed that is 10 % too high is entered, the measured wall thickness
will be approx. 10 % greater than the actual wall thickness.
The actual sound speed of a material often differs substantially from
the values published in the literature as it depends on the composi-
tion, the manufacturing process and the temperature. The sound
speeds given in annex C.1 only serve as an orientation.
Note! The longitudinal sound speed of a material can be measured pre-
cisely using a reference object of known thickness (see section
19.3.2).
