C Reference
The following tables provide assistance for the user. The accuracy of the data depends
on the composition, the temperature and the manufacturing process of the material.
FLEXIM does not assume liability for any inaccuracies.
C.1 Sound Speed of Selected Pipe and Lining Materials at 20 °C
The values of some of these materials are stored in the internal database of the transmit-
ter. Column c
flow
shows the sound speed (longitudinal or transversal) used for the flow
measurement.
The sound speed depends on the composition and the manufacturing process of the ma-
terial.
The sound speed of alloys and cast materials fluctuates strongly. The values only serve
as an orientation.
