Description (Cause)
This indicates that interface reflection
has been tracked into the lower zone
near the End of Probe where
measurements are not accurate.
This indicates that either the surface
or interface reflection has been
tracked into the upper zone near the
Reference Plane where
measurements are not accurate.
This indicates that either the surface
or interface reflection has been
tracked into the lower zone near the
End of Probe where measurements
are not accurate.
This indicates that device is not
characterized, this has an impact on
accuracy of device measurements at
different temperatures.
This indicates device is not calibrated
and impacts the accuracy of
measurements at different positions
of level

Resolution (Steps to take)
This is a condition that can occur during
normal operation and does not
generally require corrective action. If
this condition is triggered when it is not
expected, verify that the Blocking
Distance Low parameter is set correctly
for the current conditions.
If distance to interface is in Lower zone
then status associated with device
variables derived from distance to
interface will be shown as uncertain in
local display and on HART host the
status would be poor accuracy.
This is a condition that can occur during
normal operation and does not
generally require corrective action. If
this condition is triggered when it is not
expected, verify that the Blocking
Distance High parameter is set correctly
for the current conditions.
If distance to product is in Higher zone
then status associated with device
variables derived from distance to
product will be shown as uncertain in
local display and on HART host the
status would be poor accuracy.
This is a condition that can occur during

If distance to product is in Lower zone
then status associated with device
variables derived from distance to
product will be shown as uncertain in

status would be poor accuracy.
Replace the Sensor housing with
characterized Sensor housing and send
the un characterized device to factory.
Replace the Sensor housing with
calibrated Sensor housing and send the
non-calibrated device to factory.
