The device can be configured via the display module as well as the HART protocol. The
following pages describe operation and configuration of the device using the display mod-
ule. (valid from display module software version 2.0.0).

An overview of the menue structure can be found on the last page of this document.

6.1 Principles of the parameterisation concept

Basic requirement for correct level measurements are correct pressure measurements.
Please note in particular that the mounting position may lead to a change of the measured
value. Therefore, use the position correction feature in the adjustment menue once it is
installed and before the commissioning (see 6.5.4.2).

The following information is required for the hydrostatic fill level measurement:



Density of the medium



Reference point for fill level values (fill level zero)



Tank shape (for fill volume and weight)

The fill height can be calculated from the measured pressure using the density. The level
measurement is decoupled from the pressure measurement by using the level zero. The
size and shape of the tank must be defined for calculating the volume and weight.

NOTE: It would be physically correct to refer to the fill amount as a mass. However, the not
quite correct term "weight" is recognised in everyday language. The aim of the parameteri-
sation concept is to realise an intuitive access. The term "fill weight" and not "fill mass" is
therefore used below.

6.1.1

The reference point for level values

The  reference  point  for  level  values  indi-
cates which level should correspond to a fill
height  of  zero  metres.  You  can  select  this
reference  point  for  the  level  (level  zero)  re-
gardless of  the position of the process con-
nection (pressure zero).
The  reference  point  is  parameterised  by
entering the height offset. This indicates the
height difference between the pressure zero
and  the  level  zero.  A  positive  height  offset
means that the level zero is above the pres-
sure zero. The level zero is below the pres-
sure zero for a negative height offset.

Set the height offset to zero if the level zero
is at the height of the process connection.

Figure 7: Linking the level zero and pressure zero

using the height offset

The level measurement is decoupled from the pressure measurement by using the height
offset. All level measurement parameters and measured values refer to the level zero.
