Functional description
This function displays the pipe material determined via the value entered in the
function PIPE STANDARD (6520). 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 pipe standard was not available for selection and the selection OTHER was made in
the function PIPE STANDARD (6520) the pipe material must be entered here.
Options
CARBON STEEL, DUCTILE IRON, STAINLESS STEEL, SS ANSI 304, SS ANSI 316,
SS ANSI 347, SS ANSI 410, SS ANSI 430, ALLOY C, PVC, PE, LDPE, HDPE, GRP,
PVDF, PA, PP, PTFE, GLASS PYREX, ASBESTOS CEMENT, COPPER, OTHER
Factory setting
STAINLESS STEEL
Use this function to enter the thickness of the reference component (e.g. flange) as the
basis for measuring the sound velocity of the pipe.
!
Note!
This function does not appear unless the option SOUND VELOCITY PIPE was selected
in the function MEASUREMENT (6880,  ä 111).
User input
5-digit floating-point number, [unit]
Factory setting
5 mm
This function displays the sound velocity in the pipe determined via the value entered
in the function PIPE STANDARD (6520). 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 pipe standard was not available for selection and the selection OTHER was made in
the function PIPE STANDARD (6520) the sound velocity must be entered here.
Measuring the sound velocity in the pipe
If the sound velocity in the pipe is unknown, it can be measured. To do so, select the
option SOUND VELOCITY PIPE in the function MEASUREMENT (6880,  ä 111).
The sound velocity in the pipe is measured by calling up the function SOUND
VELOCITY PIPE (6524). The measured sound velocity, 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 sound velocity, select the option YES by means of the O or S
key.
!
Note!
• To measure the sound velocity, you require the ultrasonic sensors "DDU20" which
you can order as an accessory from Endress+Hauser.
• A reference value is used as a basis for measuring the sound velocity. This reference
value can be edited (see REFERENCE VALUE function, 6523).
User input
Fixed-point number 800 to 6500 m/s
Factory setting
3120 m/s
