Basic Setup with the device display

5.4.1 Function "measured value" (000)
ENDRESS + HAUSER

E
This function displays the current measured value in the selected unit (see"Customer
unit" (042) function). The number of digits after the decimal point can be selected in the "No.of
Decimals" (095) funtion.
The standard settings for PV and SV assignment are as follows:
PV corresponds to the interface layer; SV = total level

5.4.3 Function "tank properties" (002)
ENDRESS + HAUSER

+ E
This function is used to select the tank properties. Depending on the settings, the system
searches for one (fully flooded) echo or 2 (partially filled) echoes
Selection:
• Partially Filled
• Fully flooded
Partially Filled
The system searches for 2 signals in the measuring range. The upper signal is assigned to the
total level and the lower signal to the level of the interface layer. The difference between the two
levels corresponds to the thickness of the upper medium (upper phase).
Fully Flooded
The biggest signal in the measuring range is evaluated. If the signal for the total level is within
the upper blocking distance, the signal detected corresponds to the level of the interface layer.
If an echo is not found, echo loss is detected.
