Wall Thickness Measurement
Attention! Temperature fluctuations change the sound velocity of the material. The zero
adjustment of the probe using a comparative block should be performed at the
measuring location to minimise the effect of temperature fluctuations.
12.5.2 Measurement of the Sound Velocity
c-LONGITUDINAL
m/s?
M* This display appears after the calibration, if
sound velocity was selected as the quantity
of measurement. When there is no valid
measuring value, the unit of measurement
and a question mark are shown on the
lower display line.
c-LONGITUDINAL
√
5370 m/s
M* Firmly press the probe bearing a film of the
acoustic coupling component against the
test piece (the pipe) for the measurement of
its sound velocity. As soon as a valid
measuring value has been obtained, a tick
sign and the sound velocity are shown.
12.5.3 Further Information when Measuring

O F F
O
With these keys, the displays showing
further information about the measurement
status can be switched ON or OFF.
The meaning of the messages is as follows:
NO COUPLING
Wall thickness
M* No signal can be detected.
•
Either there is no coupling component,
•
or the input value for the sound
velocity in program branch
PARAMETER is inaccurate.
MATER. TOO THICK
Wall Thickness
M* The thickness of the test piece (the pipe) is
greater than the upper measuring limit of
the probe.
MATER. TOO THIN
Wall Thickness
M* The thickness of the test piece (the pipe) is
thinner than the lower measuring limit of the
probe.
ERROR SIGNAL
Wall thickness
F* FLUXUS cannot process the signal of the
probe.
