C.4 Measuring through paint and coatings
When measuring through paints and coatings the sound-velocity of the paint/coating may be significantly
different from the sound-velocity of the actual material being measured. An example of this would be a mild
steel pipe with approximately 0.6 mm (.025") of coating on the surface. The sound-velocity of the pipe is
5918 m/s (.2330 in/µsec), and the sound-velocity of the paint is 2286 m/s (.0900 in/µsec). If the gauge is
calibrated for mild steel pipe and measures through both materials, the actual coating thickness will appear
to be 2.5 times thicker than it actually is, as a result of the differences in sound-velocity.
The error can be eliminated by using the echo-echo mode to perform measurements for applications such
as these. In echo-echo mode, the paint/coating thickness will be eliminated entirely and the steel will be the
only material measured.
APPENDIX D. DATA TRANSFER SOFTWARE
Software is available which allows data to be transferred from an Elcometer 206/206DL to a PC. Presently
Elcometer supplies ElcoMaster.
The Elcometer 206 gauge is supplied without any software but ElcoMaster is available as a free download
from the Elcometer website www.elcometer.com.
The Elcometer 206DL gauge is supplied with a CD containing ElcoMaster.
