Blocking Distance
(xxx.x)
Enter the Blocking Distance
Blocking Distance defines an area near the antenna
where reflections can not be measured effectively due
to antenna ringing. It is measured from the Sensor
Reference point. Default of 15" (380 mm) minimum dis-
tance from the process connection to the maximum level.
Extend this value when necessary to block reflections
from objects close to the antenna. Output will be held
at value corresponding to Blocking Distance. Do not
allow liquid into the Blocking Distance as false readings
can result.
16
Level Offset
(xxx.x units)
Enter the Level Offset
Level Offset defines an area at the bottom of the vessel
where reflections can not be measured effectively due to
angled bottoms, heating coils, reflections from flat metal
tank bottoms in low dielectric applications, etc. It is the
distance from the bottom of the tank to the lowest valid
level reading. Level reading will never be lower than
Level Offset value.
