Name (number), function Adjustable value range Description
Default value
Zero-level distance (P04),
Set container height
0...60 m
(0…200 ft)
It provides the basis for level
measurement calculations. The
distance between the plane of
the lower sealing surface of the
mechanical connector (the lower
plane of the ange in the case of a
anged version) and the reference
point at the bottom of the tank. Its
value must be set in a distance unit
(Unit - P00b).
Note: If measured distance is
between this distance and dead
zone, then this distance will be held.

Minimum measuring distance…
probe length (P03)
The dead zone is the distance
between the plane of the lower
sealing surface of the mechanical
connection (the lower plane of the
flange in the case of the flanged
version) and the highest level in the
tank. Signals generated within the
dead zone are not processed. The
current loop output does not follow
the dead zone level signal. Its value
must be set in distance units (Length
unit – P00b).
Note: If the measurement exceeds
this distance then this distance will
be held.

“Minimum measuring distance”
according to the Probe data table
Tank full limit (P29)
Limits are 0 to Probe length (P03). Echoes between this and P05
are processed. However if the
measurement distance is in this
range then the “Tank full limit
distance” is returned or used up for
calculations.
Factory value minimum
