Basic Measurement
The pipe and fluid parameters are entered for the selected measuring point (see chapter 5). The parameter ranges are
limited by the technical characteristics of the transducers and the of transmitter.
11.1
Input of the Pipe Parameters
11.1.1
Outer Pipe Diameter/Pipe Circumference
It is possible to enter the pipe circumference instead of the outer pipe diameter (see section 16.2.1).
If the input of the pipe circumference is activated and
0
(zero) is entered in
Outer Diameter
, the menu item
Pipe Cir-
cumfer.
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.
11.1.2
Pipe Wall Thickness
11.1.3
Pipe material
The pipe material has to 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 shown in the scroll list (see section 15.5).
Attention!
Observe the "Safety Instructions for the Use in Explosive Atmosphere" (see document SIFLUXUS).
Note!
During the parameter input, the transducers have to be connected to the transmitter.
Note!
The parameters will only be stored when the program branch
Parameter
has been edited in its en-
tirety.
Select the program branch
Parameter
. Press ENTER.
Select the channel for which the parameters are to be entered.
Press ENTER.
Enter the outer pipe diameter. Press ENTER.
An error message will be displayed if the entered parameter is not within the range. The
limit is displayed.
Example: upper limit 1 100 mm for the connected transducers and for a pipe wall thickness
of 50 mm.
Enter the pipe wall thickness. Press ENTER.
Note!
The inner pipe diameter (= outer pipe diameter - 2x pipe wall thickness) 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 sec-
tion 13.9).
Select the pipe material.
If the material is not in the scroll list, select
Other Material
. Press ENTER.
