The following conditions will impact the Blind Zones:
• If the single lead probes or twin probes are installed in a nozzle, the nozzle height shall
be added to the specified Upper Blind Zone.
• The measuring range for the PTFE covered flexible single lead probe includes the
weight when measuring on a high dielectric media.
• When using a metallic centering disc, the Lower Blind Zone is 8 in. (20 cm), including
weight if applicable. When using a PTFE centering disc, the Lower Blind Zone is not
affected.
Figure A-4 , Figure A-6, and Figure A-5 illustrate the accuracy over measuring range at
reference condition with alternating probe types and varying dielectric constant of the
product.

Note
Measurements may not be possible in the Blind Zones, and measurements close to the
Blind Zones will have reduced accuracy. Therefore, the 4-20 mA points should be
configured outside these zones.
