TRANSMITTER SETUP

5. Set the process conditions:
a. Process dielectric constants (ENV_DICECTR_CONST)
b. Process conditions (ENV_ENVIRONMENT)
Rapid level changes
Turbulent Surface
Foam
Solid Products
Additional configuration can be made in Appendix B: Level Transducer Block.
Optimize the transmitter for measurement conditions where the
level changes quickly due to filling and emptying of the tank. A
standard configured transmitter is able to track level changes of
up to 4 inch/s (100 mm/s). When the Rapid Level Changes
check box is marked, the transmitter can track level changes of
up to 8 inch/s (200 mm/s).
This parameter should be used if the tank shows a turbulent
surface. The reason for the turbulence might be splash loading,
agitators, mixers, or boiling product. Normally the waves in a
tank are quite small and cause local rapid level changes. By
setting this parameter the performance of the transmitter will be
improved when there are small and quickly changing
amplitudes and levels.
Setting this parameter optimizes the transmitter for conditions
with weak and varying surface echo amplitudes, which are
typical for foam.
Setting this parameter optimizes the transmitter 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 buildup.
