factory?]
Note:
: :
: For waveguide antennas used as stillpipes, this value is on the product tag.
The propagation factor is constant for a given
pipe diameter, or can be determined by
comparing the radar distance reading to the
actual process material distance (measured
from the face of the IQ 300 flange).

Rate Parameters
These parameters determine how material level changes are reported.
P700 Maximum Fill Rate
Adjusts the IQ 300 response to increases in the actual material level (or an advance to a
higher Failsafe Material Level, P071).
