Tank Geometry
The Gauge Height (RGH) is the distance from the Upper Reference Point
to the bottom of the tank. When setting the Reference Gauge Height, keep
in mind that this value is used for all measurements performed by the
APEX Radar Gauge. The Gauge Height must be set in linear (level) units,
such as feet or meters, regardless of primary variable assignment.
The Upper Null Zone (UNZ) should not be changed unless there are
disturbances at the top of the tank. By increasing the Upper Null Zone
value measurements in this region can be avoided. The UNZ is equal to
19.6 inches (0.5 m) in the factory configuration.
NOTE
The gauge cannot reliably read measurements too close to the antenna.
The Lower Null Zone (LNZ) should not be changed unless there are
disturbances at the bottom of the tank. By increasing the Lower Null Zone
value measurements in this region can be avoided. The LNZ is equal to
-19.6 inches (-0.5 m) in the factory configuration.
