Tank Shape

PRELIMINARY
The Rosemount 3308 transmitter is relatively insensitive to objects in the tank
since the radar signal is transmitted along a probe.
Avoid physical contact between probes and agitators as well as applications
with strong fluid movement unless the probe is anchored. If the probe can
move within 1 ft (30 cm) away from any object, such as an agitator, during
operation then probe tie-down is recommended.
In order to stabilize the probe for side forces, it is possible to hang a weight at
the probe end (flexible probes only) or fix/guide the probe to the tank bottom.
The guided wave radar transmitter is insensitive to the tank shape. Since the
radar signal travels along a probe, the shape of the tank bottom has virtually
no effect on the measurement performance. The transmitter handles flat or
dish-bottom tanks equally well.
