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.

This function displays the thickness of the pipe walls determined via the value 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 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,  ä 111). 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
measurement 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.
!
Note!
To measure the wall thickness, you require the ultrasonic sensors "DDU20" which you
can order as an accessory from Endress+Hauser.
