Endress+Hauser Proline Prosonic Flow 93 - Function Description

7 Block BASIC FUNCTION PROline Prosonic Flow 93 FOUNDATION Fieldbus
58 Endress+Hauser
REFERENCE VALUE
(6523)
 Note!
This function does not appear unless “SOUND VELOCITY PIPE” was selected
in the MEASUREMENT function (6880, Page 63).
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.
User input:
5-digit floating-point number, [unit]
Factory setting:
5 mm
SOUND VELOCITY PIPE
(6524)
Use this function to enter the sound velocity in the pipe.
Measuring the sound velocity in the pipe
If the sound velocity in the pipe is not known, it can be measured. To do so,
“SOUND VELOCITY PIPE” must be set in the MEASUREMENT function (6880,
Page 63).
The sound velocity in the pipe is measured by calling up the SOUND
VELOCITY PIPE (6524) function. 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
 key, the SAVE prompt appears. To accept
the measured sound velocity, select the option “YES” by means of the
 or 
key.
 Note!
A reference value is used as a basis for measuring the sound velocity. This
reference value can be edited, (see Page 58).
User input:
Fixed-point number 800...6500 m/s
Factory setting:
3120 m/s
PIPE CIRCUMFERENCE
(6525)
Use this function to enter the circumference of the pipe.
User input:
Fixed-point number 31.4...15708.0 mm
Factory setting:
279.3 mm
PIPE DIAMETER
(6526)
Use this function to enter the diameter of the pipe.
User input:
Fixed-point number 10.0...5000.0 mm
Factory setting:
88.9 mm
