BASIC FUNCTION
PIPE MATERIAL This function displays the pipe material determined via the value entered in the function
(6522) 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, OTHER
Factory setting:
STAINLESS STEEL
REFERENCE VALUE Use this function to enter the thickness of the reference component (e.g. flange) as the
(6523) basis for measuring the sound velocity of the pipe.
!
This function does not appear unless the option SOUND VELOCITY PIPE was selected in
the function MEASUREMENT (6880, Page 120).
User input:
5-digit floating-point number, [unit]
Factory setting:
5 mm
SOUND VELOCITY PIPE This function displays the sound velocity in the pipe determined via the value entered in
(6524) 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, Page 120). 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.
!
• To measure the sound velocity, you require the ultrasonic sensors "DDU18" which
• A reference value is used as a basis for measuring the sound velocity. This reference
User input:
Fixed-point number 800...6500 m/s
Factory setting:
3120 m/s
