Measuring Compound Profiles
When the material to be measured has a compound prole (such as bend
of a pipe), one can use the procedures to measure cylindrical surfaces.
The exception is that one should have two analyses and get two results
when the probe’s crosstalk interlayer plate is being both parallel and
perpendicular to the axial line of the object. Take the minimum readout as
the material thickness.
Measuring an Un-Parallel Surface
To get a satisfactory ultrasonic response the other surface of the object
must be parallel to or co-axial with the surface to be measured, otherwise
it will cause a measuring error or even provide no display.
Influence of Material’s Temperature
Both the thickness and transmitting speed of ultrasonic wave are
inuenced by temperature. If there is a high requirement of measuring
accuracy, one can use comparison method by:
• Use a test piece of the same material being measured, under
same temperature
• Obtain the temperature compensation coefcient
• Use this coefcient to correct the actual measurement of the
object
Material with Large Attenuation
Material with porous and coarse particles (such as bre) will cause a large
scatter and energy attenuation in the ultrasonic wave. This will cause
abnormal readouts or provide no display (generally, the abnormal readout
are less than the actual thickness). These type of materials cannot be
measured by this meter.
