Sound speed of the pipe material
• Enter the sound speed of the pipe material.
• Press ENTER.
•Select Transverse wave or Longitudinal wave.
• Press ENTER.
These displays will only be indicated if Other material is selected.
For the sound speed of some materials see annex C.
Roughness of the pipe material
The flow profile of the fluid is influenced by the roughness of the inner pipe wall.
The roughness is used for the calculation of the profile correction factor.
In most cases, the pipe roughness cannot be exactly determined and must therefore be estimated.
• Press ENTER if the pipe has a lining. The roughness of the lining is included into the calculation.
• Enter the roughness of the pipe material in case the pipe has no lining. Press ENTER.
This display will only be indicated if Other material is selected.
For the roughness of some materials see annex C.
Wall thickness
• Enter the pipe wall thickness.
• Press ENTER.
Lining
•Select Yes if the pipe has a lining. Select No if the pipe has no lining.
• Press ENTER.
Lining material
• Select the lining material.
• Press ENTER.
• If the lining material is not included in the scroll list, select the list item Other material.
• Press ENTER.
This display will only be indicated if Yes is selected in the menu item Lining.
