middle point of the highest density measuring point. For a good
density measuring result, the value must be at least 0.3 m (1 ft).

measuring point. For a good density measuring result, the value
must be at least 0.2 m (8") above the motor limit switch low.
Determines the direction in which a tank profile (or interface profile)
is measured.
Scan direction down: from product surface downwards
Scan direction up: from bottom upwards
Note: When also water bottom is measured first via the water dip
command, it is advised to set the scan direction upwards. Then the
combined dip command directs the displacer downwards for water
measurement, and on the way back, density is measured.
The number of measurement points for one density measurement
equally distributed over one drum rotation.
Determines the measurement method:
•
Multi over drum: measures at multiple points of one drum
rotation to get an accurate density measurement. This
method is the most accurate.
• One drum position: measures only at one drum position.
For an accurate density measurement, the unbalance
compensation must be enabled. This requires a valid
unbalance table (refer to section 9.1.3).
Reset the TII-SRV to activate the settings.
The following entities must be programmed before the 954 SmartServo
FlexLine gauge can perform an Interface Profile density measurement.
Refer to . The entities do not require a reset command.

measurement can be performed at any location in the tank.
[Interface profile start level] specifies the highest interface level (so
that is independent of the density scan direction).
Refer to Error! Reference source not found.
density start level measurement can be performed at any location in
the tank. [Interface profile stop level] specifies the lowest interface
level (so that is independent of the density scan direction).
Determines the direction in which an interface profile (or tank
profile) is measured.
Scan direction down: from [Interface profile start level]
downwards
Scan direction up: from [Interface profile stop level] upwards
