VEGA VEGAFLEX 63 Foundation Fieldbus - Manual (Page 11)

The reference plane for the measuring range of the sensors is the
lower edge of the flange.
Keep in mind that a min. distance must be maintained below the
reference plane and possibly also at the end of the probe -
measurement in these areas is not possible (dead band). Keep in mind
that the cable length cannot be used all the way to the end because
measurement in the area of the gravity weight is not possible. These
min. distances (dead bands) are listed in chapter "Technical data".
Keep in mind for the adjustment that the default setting for the
measuring range refers to water.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
4 .2 Mounting instructions
Mount VEGAFLEX 63 in such a way that the distance to vessel
installations or to the vessel wall is at least 300 mm (12 in).
During operation, the probe must not touch any installations or the
vessel wall.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.
