Vessel characteristics
2.8.1
Heating coils, agitators
Because the radar signal is transmitted along a probe, the Rosemount 5300 Radar
Transmitter is generally not affected by objects in the tank. Avoid physical contact with
metallic objects when twin lead or single lead probes are used.
Avoid physical contact between probes and agitators, as well as applications with strong
fluid movement, unless the probe is anchored. If the probe is able to move 1 ft. (30 cm)
from any object, such as an agitator, during operation, the probe tie-down is
recommended.
To stabilize the probe for side forces, a weight may be hung at the probe end (flexible
probes only) or fix/guide the probe to the tank bottom.
2.8.2
Tank shape
The guided wave radar transmitter is insensitive to 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 can handle flat or dish-bottom tanks.
