6.4 Basic Setup with the VU331
Function "Measured Value" (000)
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) function.
The standard settings for PV and SV assignment are as follows:
PV corresponds to the interface layer; SV = total level
6.4.1 Function group "Basic Setup" (00)
Function "Tank Properties" (002)
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.
Options:
• 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.
!
Note!
• If "fully flooded" is selected, it is absolutely essential that the upper signal for the total level is
within the upper blocking distance so that it is not evaluated incorrectly. The setting for the upper
blocking distance is an integral part of the basic setup if "fully flooded" is selected.
• A change in the total level when "fully flooded" is selected impacts the accuracy.
