Configuration Parameters
November 2017
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
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.
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.
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.
C.3.3

Volume

Select if the volume measurement should be calculated from the configured tank dimensions or a
strapping table.
Strapping tables can be used for irregularly shaped tanks, to eliminate errors due to bulging when
product is added to a tank, or if a pre-defined tank type does not provide sufficient accuracy.
