Submerged is used for applications where the probe is fully submerged in
liquid. In this mode, the transmitter ignores the upper product level. See
“Section 7: Interface Measurements with Fully Submerged Probes” for more
information.
NOTE!
Only use Submerged for applications where the interface is measured with a
fully submerged probe.
F OUNDATION Fieldbus parameter:
TRANSDUCER 1100>MEAS_MODE
Dielectric Constant/Dielectric Range
The dielectric constant of the product is used for setting the appropriate signal
amplitude thresholds, see Section 7: Service and Troubleshooting for more
information on amplitude threshold settings. Normally, this parameter does
not need to be changed for level measurements. However, for some products,
measurement performance can be optimized by setting the proper product
dielectric constant.
For Interface Level measurements, the dielectric constant of the upper
product is essential for calculating interface level and the upper product
thickness. By default, the Upper Product Dielectric parameter is about 2.
Set the Upper Product Dielectric Constant to a value that corresponds to
the current product.
