This means that e.g. the sound path between the trans-
mitter and receiver element of the first pair of elements
is known, composed of the delay line (S
T
, S
R
) and the
basic path (S
B
).
On the basis of this known path and the time of flight
measured in each case, the instrument can then directly
determine and display the sound velocity in a non-coat-
ed test object (Auto-V function).
At the same time, the sound velocity determined in this
way can be used for the exact measurement of wall
thickness. Thanks to the determination of the sound ve-
locity in the material, taking place simultaneously with
the wall thickness measurement, velocity variations
caused by the material and the temperature are also im-
mediately taken into consideration in the wall thickness
measurement.
When applying the TopCOAT method, the
DMS Go+ TC does not use the measurements of the
first pair of transducer elements for determining the
sound velocity in the material but for determining the
thickness of coating on the basis of the extended sound
path
(S
T
+ S
C
+ S
B
+ S
C
+ S
R
).
The sound velocities in the coating and in the test object
are assumed to be known and constant.
