Transition Zones
Transition zones are areas where measurements are
non-linear or will have reduced accuracy. See picture
and table below.
If measurements are desired at the very top of the
tank it is possible to mechanically extend the nozzle
and use the coaxial probe. Then the upper transition
zone is moved into the extension.
NOTE
The 4-20 mA set points are recommended to be
configured between the transition zones, within the
measuring range (see picture and diagram above).

For a flexible single lead probe with chuck, the lower
transition zone is measured upwards from the upper
clamp.

(2) The distance from the lower reference point where measurements have reduced accuracy, see picture above.
(3) Note that the weight length adds to non-measurable area and is not included in the diagram. See “Dimensional Drawings”.
(4) The measuring range for the PTFE covered Flexible Single Lead probe includes the weight when measuring on a high dielectric media.
(5) If using a stainless steel centering disc, the lower transition zone is 8 in. (20 cm). If using a PTFE centering disc, the lower transition zone is not affected.
