Section 4. Configuration
There are a number of advanced configuration options for the Rosemount
5900S gauge which may be useful in certain situations. These options are
available via TankMaster Winsetup and the 5900 RLG Properties window.
Foam
You can use this parameter to optimize the gauge for conditions with low and
varying surface echo amplitudes such as foam. When the foam is light and
airy the actual product level is measured. For heavy and dense foam the
transmitter measures the level of the upper surface of the foam.
Turbulent Surface
Splash loading, agitators, mixers, or boiling products may cause a turbulent
surface. Normally the waves in a tank are quite small and cause local rapid
level changes. By setting the Turbulent Surface parameter the performance of
the level gauge will be improved when there are small and quickly changing
amplitudes and levels.
Rapid Level Changes
Optimize the level gauge for measurement conditions where the product level
changes quickly due to filling and emptying of the tank. The Rosemount
5900S is able to track level changes of up to 1.5 inch/s (40 mm/s). The Rapid
Level Changes function allows the 5900S to track level changes of up to 8
inch/s (200 mm/s).
The Rapid Level Changes function shall not be used in normal conditions
when the product surface moves slowly.
Solid Products
Setting this parameter optimizes the gauge for solid products, for example
concrete or grains, which are not transparent for radar signals. For instance,
this parameter can be used when the application is a silo with product
build-up.
Product Dielectric Range
The Dielectric Constant is related to the reflectivity of the product. This
parameter can be used to optimize measurement performance. However, the
level gauge will still be able to perform well even if the actual Dielectric
Constant differs from the configured value.
The Tank Type and Tank Bottom Type parameters optimize the 5900S for
various tank geometries and for measurements close to the tank bottom.
