FLUXUS G60x 11 Basic Measurement
It is possible to enter the pipe circumference instead of the outer pipe diameter (see sec-
tion 17.2.1).
If the input of the pipe circumference has been activated and 0 (zero) is entered for the
Outer Diameter, the menu item Pipe Circumfer. will be displayed. If the pipe cir-
cumference is not to be entered, press key BRK to return to the main menu and start the
parameter input again.
11.1.2 Pipe Wall Thickness
11.1.3 Pipe Material
The pipe material must be selected to be able to determine the sound speed. The sound
speed for the materials in the scroll list are stored in the transmitter.
It can be specified which materials will be displayed in the scroll list (see section 16.5).
When the pipe material has been selected, the corresponding sound speed is set auto-
matically. If Other Material has been selected, the sound speed must be entered.
For the sound speed of some materials see annex C.1.
Enter the pipe wall thickness. Press ENTER.
Note! The inner pipe diameter (= outer pipe diameter - 2x pipe wall thick-
ness) is 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 13.8).
Select the pipe material.
If the medium is not in the scroll list, select Other Mate-
rial. Press ENTER.
Enter the sound speed of the pipe material. Press ENTER.
Note! Enter the sound speed of the material (i.e. longitudinal or transversal
speed) which is nearer to 2500 m/s.
