ment of aggressive liquids or with hygienic requirements. It is suitable
Serial number - Instru-

3 Product description
VEGAPULS 63 • HART and accumulator pack
40794-EN-200427
for applications in storage tanks, process vessels, dosing vessels and
reactors.
The standard electronics enables the use of instruments in products
withanεrvalue≥1.8.Theelectronicsversionwithincreasedsensitiv-
ity also enables use of the instrument in applications with very poor
reectivepropertiesorproductswithanεrvalue≥1.5.Thevaluesthat
can actually be reached depend on the measuring conditions and the
antenna system i.e. the standpipe or bypass tube.
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereectedbytheproduct
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropri-
ate output signal and outputted as measured value.
The instrument is powered via an integrated accumulator. This allows
operation of the instrument independently of the mains or a control
system.To achieve a longer battery lifetime, the instrument is preset
to HART multidrop. This puts a load of only 4 mA current on the ac-
cumulator.
3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter "Supplement -

Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter "Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Makesurethatthedegreeofcontaminationspeciedinchapter
"Technical data" meets the existing ambient conditions.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter "Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.

When mounting the VEGAPULS 63, keep a distance of at least
200 mm (7.874 in) to the vessel wall. If the sensor is installed in the
center of dished or round vessel tops, multiple echoes can arise.
These can, however, be suppressed by an appropriate adjustment
(see chapter "Setup").
If you cannot maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup on

In vessels with conical bottom it can be advantageous to mount the
sensor in the centre of the vessel, as measurement is then possible
down to the bottom.

The PTFE washer in 8 mm version can be exchanged by the user in
case of wear or damage.
Proceed as follows while dismounting:
1. Dismount and clean the instrument, note chapters "Dismounting
steps" and "Maintenance"
2. Unscrew and remove the PTFE disc by hand, protecting the
thread against dirt.

In liquids, direct the sensor as perpendicular as possible to the me-
dium surface, to an achieve optimum measurement.

Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interferingreectionsfromtheagitatorsaresavedwiththebladesin
dierentpositions.

Throughtheactionoflling,stirringandotherprocessesinthevessel,
compact foam can form on the medium surface, damping the emitted
signals considerably.
If foams are causing measurement errors, the biggest possible radar
antennas, the electronics with increased sensitivity or low frequency
radar sensors (C band) should be used.
