Input of pipe parameters
Outer pipe diameter/pipe circumference
• Enter the outer pipe diameter.
• Press ENTER.
An error message will be displayed if the entered parameter is outside the range. The limit is displayed.
Example: upper limit 1100 mm for the connected transducers and for a pipe wall thickness of 50 mm.
It is possible to enter the pipe circumference instead of the outer pipe diameter, see section 18.1.
If the input of the pipe circumference is activated and 0 (zero) is entered in
Outer Diameter
, the menu item
Pipe Circumfer.
will be displayed. If the pipe circumference is not to be entered, press key BRK to return to the main
menu and start the parameter input again.
Pipe wall thickness
• Enter the pipe wall thickness.
• Press ENTER.
Pipe material
The pipe material has to be selected to be able to determine the corresponding sound speed.
The sound speeds for the materials in the scroll list are stored in the transmitter.
• Select the pipe material.
• Press ENTER.
• If the material is not in the scroll list, select
Other Material
.
• Press ENTER.
Sound speed of the pipe material
• Enter the sound speed of the pipe material.
• Press ENTER.
These displays will only be indicated if
Other Material
is selected.
For the sound speed of some materials, see annex C.
Parameter\Outer Diameter
Notice!
The inner pipe diameter (= outer pipe diameter - 2 × pipe wall thickness) will be calculated internally.
If the value is not within the inner pipe diameter range of the connected transducers, an error message will be displayed.
It is possible to change the lower limit of the inner pipe diameter for a given transducer type, see section 16.10.

Notice!
There are 2 sound speeds for pipe materials, the longitudinal and the transversal one. Enter the sound speed which
is nearer to 2500 m/s.
