Страница: 262 / 274

Bottom shape height
The height of the shape at tank bottom (typically from shape floor to shape bottom,
measured at cylinder center line).
End shape length
The width of the spherical cap at tank end (measured at cylinder center line).
Show negative level as zero
When this setting is selected and the product surface is at or below Zero Level, the level
measurement output will be zero.
C.3.2 Environment
Product type
The media (liquid/solid) used in the monitored process.
• Liquid (requires measurement type code 1 or 4)
• Solid (requires measurement type code 3 or 4)
The solids measurement mode should never be used for measuring liquid products due to
the solids specific signal processing method, and vice versa.
Note
Solid is not supported for a Rosemount 5408:SIS operating in Safety (SIS) mode.
Process conditions
Foam
This parameter should be used if there is, or may be, surface foam. When setting this
parameter, the transmitter is optimized for conditions with weak and varying surface echo
amplitudes, which is typical for presence of surface foam.
Turbulent surface
Set this parameter to improve the performance of the transmitter when there are small
and local rapid level changes caused by surface turbulence. The reason for the turbulence
might be splash loading, agitators, mixers, or boiling product.
Maximum level rate
Fastest rate that may occur in the monitored process to (partially) fill or empty this tank.
Note that product level rate may be higher during upset conditions.
Product dielectric range
Select the range of the dielectric constant for the product in the tank. If the range is not
known, or if the product in the tank is changed on a regular basis, then select Default.
