BASIC FUNCTION
CIRCUMFERENCE This function displays the outer circumference of the pipe determined via the value
(6525) entered in the function NOMINAL DIAMETER (6521). If you edit the predetermined
value the pipe standard will be reset to the option OTHERS and the function NOMINAL
DIAMETER (6521) does not appear.
If a nominal diameter was not available for selection and the selection OTHER was made
in the function NOMINAL DIAMETER (6521) the outer circumference must be entered
here.

PIPE DIAMETER This function displays the outer diameter of the pipe determined via the value entered in
(6526) the function NOMINAL DIAMETER (6521). If you edit the predetermined value the pipe
standard will be reset to the option OTHERS and the function NOMINAL DIAMETER
(6521) does not appear.
If a nominal diameter was not available for selection and the selection OTHER was made
in the function NOMINAL DIAMETER (6521) the outer diameter must be entered here.
User input:
Fixed-point number 10.0...5000.0 mm
Factory setting:
88.9 mm
WALL THICKNESS This function displays the thickness of the pipe walls determined via the value entered in
(6527) the function NOMINAL DIAMETER (6521). If you edit the predetermined value the pipe
standard will be reset to the option OTHERS and the function NOMINAL DIAMETER
(6521) does not appear.
If a nominal diameter was not available for selection and the selection OTHER was made
in the function NOMINAL DIAMETER (6521) the thickness of the pipe wall must be
entered here.
Measuring the wall thickness
If the wall thickness is unknown, it can be measured. To do so, select the option WALL
THICKNESS in the function MEASUREMENT (6880, Page 120). The wall thickness is
measured by calling up the function WALL THICKNESS (6527). The measured wall
thickness, the signal strength and a bar graph appear on the local display. The measure-
ment is valid if 100% is achieved in the bar graph. If you confirm the function with the F
key, the SAVE prompt appears. To accept the measured wall thickness, select the option
YES by means of the O or S key.
!
To measure the wall thickness, you require the ultrasonic sensors "DDU19" which you
can order as an accessory from Endress+Hauser.
