Tank height
The Tank Height is the distance from the Upper Reference Point to the bottom of the tank
(Zero Reference Point). The transmitter measures the distance to the product surface and
subtracts this value from the Tank Height to determine the level.
Ensure the Tank Height is as accurate as possible, since a Tank Height error results in a
corresponding level value offset error.
When setting the Tank Height, keep in mind that this value is used for all level
measurements performed by transmitter. The Tank Height must be set in linear (level)
units, such as feet or meters, regardless of primary variable assignment.
Mounting type
Select option best describing how device is mounted on the tank.
Inner diameter, pipe/chamber/nozzle
Select the inner diameter for the pipe, chamber or nozzle in which the probe is mounted.
Nozzle height
The distance between the Upper Reference Point (normally the lower side of the device
flange) and the end of the nozzle. Note that nozzle may extend into the tank (which
should be included in the height).
Measurement mode
Select the Measurement Mode to use in the device. Some modes require software options
to be enabled in the device. You can upgrade the device to enable more software options.
Interface Level with Submerged Probe is used for applications where the probe is fully
immersed in liquid. In this mode the transmitter ignores the upper product level.
Note
Only use Interface Level with Submerged Probe for applications where interface is
measured for a fully immersed probe.

Upper product dielectric constant
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. The default value for the Upper Product
Dielectric Constant is 2.
For level measurements, the Upper Product Dielectric Constant parameter corresponds to
the dielectric constant of the product in the tank.
