Through this additional selection, the sensor is adapted perfectly to
the product and measurement reliability, particularly in products with
poor reflective properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
Apart from the medium, the vessel shape can also influence the
measurement. To adapt the sensor to these measuring conditions,
this menu item offers different options depending on whether liquid
or bulk solid is selected. With "Liquids" these are "Storage tank",
"Stilling tube","Open vessel" or "Stirred vessel", with "Solid", "Silo" or
"Bunker".

Storage tank
Information:
With VEGAPULS 63 with electronics version "Increased safety",
"Solid" is preset as factory setting. However, the instrument should be
used preferably in liquids. In such cases, the vessel form should be
set to "Storage tank" during setup.
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
The channel is the input selector switch for function block (FB) of
the sensor. Within the function block, additional scalings (Out-Scale)
are carried out. In this menu item, the value fir the function block is
selected:
•
SV1 (Secondary Value 1):
– Percent with radar, guided microwave and ultrasonic sensors
– Pressure or height with pressure transmitters
•
SV2 (Secondary Value 2):
– Distance with radar, guided microwave and ultrasonic sensors
– Percent with pressure transmitters
•
PV (Primary Value):
– Linearised percentage value

A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage and vessel volume. By activating the appropriate curve, the
volume percentage of the vessel is displayed correctly. If the volume
