Theory of operation

Rosemount
material type, product characteristics, storage silo type, size, bin or container, and harshness of the
storage environment. The product incorporates unique dust-penetrating technology to achieve an
unrivaled degree of process measurement and inventory control.
The Rosemount 5708 include an array of three antennas that generate low frequency acoustic signals
and receive echo signals from the contents of the silo, bin, or other container type. Using these antennas,
the unit measures not only the time/distance of each echoed signal but also its direction and generate a
coordinate of the echo inside the vessel.
The built-in digital signal processor digitally samples and analyses the echoed signals and produces
accurate measurements of the level and volume of the stored contents, and can generate a 3D
visualization position and form of the material within the container for displaying on remote computer
screens.

Applications

2.2.1

Wide application range

The Rosemount 5708 can measure practically any kind of solid material, stored in a variety of containers,
including large open bins, bulk solid storage rooms, stockpiles and warehouses, mapping loads that
randomly form over time inside silos, and many other challenging applications that were not possible
until now. The Rosemount 5708 can measure ranges of up to 230 ft. (70 m) and generate 3D
visualization of the material surface when installed according to the guidelines within this manual.
