954 SmartServo FlexLine
8.5 Interface measurement
The 954 SmartServo FlexLine can measure three different interfaces.
Interface 1 (I1) is normally used to measure the product level. Interface
3 (I3) can be used to measure the product / water interface. Interface 2
(I2) is a setting for a special measurement (i.e. interface between two
product layers).
Entity name Entity name
(SmartView) Description
[Interface 1] [Interface 1]
(Product level)
Interface 1 measurement (based on set point 1);
normally used for product measurement.
[Interface 2]
[Interface 2]
(Interf2 level)
Interface 2 measurement (based on set point 2); setting
for special measurement.
[Interface 3] [Interface 3]
(Water level)
Interface 3 measurement (based on set point 3);
normally used for product / water measurement.
The default setting is on interface 1 (I1). If one of the other two interface
measurements is selected, the gauge will remain on that interface
measurement till the default measurement (I1) is selected.
8.6 Dip mode
When the gauge is in dip mode the displacer will be set at some
distance [Dip height] above interface 1 (product surface). After a certain
time [Dip interval time] a single product measurement is executed. After
the interface has been measured, the displacer will be raised over the
dip height.
The level, shown on the display and transmitted to the host, will be the
dipped level and not the actual displacer position.

(SmartView) Description
[Dip mode]
[Dip mode]
(Product level)
Activates the dip mode. In dip mode the displacer is
positioned at distance [Dip height] above the
product and after a time interval [Dip interval time],
the product is dipped.
The dip mode is cancelled when one of the interface measurements is
selected.
For the dip mode, entities [Dip height] and [Dip interval time] must be
set (checked) during commissioning (or at a later stage):

(Displ. level)
In dip mode, the displacer is raised above the
product over the dip height distance.
[Dip time interval]
<[Dip interv. Time [s]]
(Displ. level)
The time in between 2 consecutive interface 1 dips.
