Probe length
The probe length is the distance between the Upper Reference Point and the end of the
probe. If a weight is used at the end of the probe it shall be included.
2.2
Measuring range
The measuring range depends on probe type, dielectric constant of the product, and
installation environment, and is limited by the Blind Zones at the very top and bottom of
the probe. In the Blind Zones, the accuracy exceeds ±1.18 in. (30 mm), and measurements
may not be possible. Measurements close to the Blind Zones will have reduced accuracy.
illustrates how the measuring range is related to the Blind Zones and the areas
with reduced accuracy.

Note
Measurements may not be possible in the Blind Zones, and measurements close to the
Blind Zones will have reduced accuracy. Therefore, the alarm points should be configured
outside these zones.
