a)
Since pipe dimensions may vary slightly, the propagation factor may also vary.
b)
CLEF range covers the whole measurement range except first 700 or 1000 mm from sensor
reference point
Note
Flanged encapsulated antenna
For Flanged encapsulated antenna (7ML5432) match the process connection size to the
pipe diameter.
For example, DN 80/3" flange to DN 80/3" pipe.
