Product dielectric range
Note
Applicable to “Liquid Product Level” and “Solid Product Level” measurement modes.
Enter the range of the dielectric constant (DC) for the product in the tank. The selected
range of dielectric constant is used for setting the automatically calculated amplitude
thresholds.
Upper product dielectric constant
Note
Applicable to “Interface Level with submerged” and “Product Level and Interface Level”
measurement modes.
The Upper Product Dielectric Constant (DC) should be entered as accurately as possible.
The dielectric constant of the upper product is essential for calculating the interface level
and the upper product thickness. In addition, this value is used for setting the
automatically calculated amplitude thresholds.
In case it is unknown, use the Dielectric Constant Chart or Upper Product Dielectric
Constant Calculator embedded in the configuration tools as help when configuring the
DC.
If the dielectric constant of the lower product is significantly smaller than the dielectric
constant of water, you may need to make special adjustments. The dielectric constant of
water is 80.

3. Select the Dielectric Constant Chart button.
Use the upper product dielectric constant calculator in Rosemount
Radar Master
The Upper Product Dielectric Constant Calculator lets you calculate the dielectric constant
of the upper product based on the following input:
• Actual upper product thickness
• The dielectric constant value stored in the transmitter
• The upper product thickness presented by the transmitter
