4. Carry out the adjustment in the menu items "Min. adjustment" and
"Max. adjustment".
The radar sensor measures the distance from the sensor to the
product surface. For indication of the real level, an allocation of the
measured distance to the percentage height must be carried out.

For this adjustment, the distance is entered when the vessel is full
and nearly empty. If these values are not known, an adjustment with
other distances, for example, 10 % and 90 % is also possible. Starting
point for these distance specications is always the seal surface of
the thread or ange.
1. In the menu "Additional settings", menu item "Damping" you can
adjust the requested damping of the output signal.
2. Select the output characteristics in the menu item "Current out-
put".
The quick start is then nished. For further information see chapter

3.2 Principle of operation
The VEGAPULS 63 is a radar sensor for continuous level measure-
ment of aggressive liquids or with hygienic requirements. It is suitable
for applications in storage tanks, process vessels, dosing vessels and
reactors.
The standard electronics enables the use of instruments in products
with an εr-Wert ≥1.8. The electronics version with increased sensitivity
enables the use of the instrument also in applications with very poor
reective properties or products with an εr value ≥1.5. The values that
can be actually reached depend on the measurement conditions, the
antenna system or 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.
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
following ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. 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 under 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:

4.1 General instructions
With instruments with threaded process tting, suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain o. This ap-
plies mainly to outdoor mounting as well as installation in areas where
high humidity is expected (e.g. through cleaning processes) or on
cooled or heated vessels.
Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
tting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.
You can nd the specications in chapter "Technical data" and on the
nameplate.
4.2 Instructions for installation
The PTFE washer of the antenna encapsulation is also the process
seal. The following must be fullled for an eective sealing:
1. Make sure the number of ange screws corresponds to the num-
ber of ange holes
2. Use disc springs to compensate the preload loss of the PTFE
washer

3. Tighten screws with the necessary torque (see chapter "Technical
data")
4. Retighten screws in regular intervals depending on process pres-
sure and temperature

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 keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo stor-
age later with existing buildup.

(7.87 ")
Fig. 7: Mounting of the radar sensor on round vessel tops
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.

Do not mount the instruments in or above the lling stream. Make sure
that you detect the product surface, not the inowing product.

Flush mounting
The best way to mount the sensor, also with respect to cleanability, is
ush on a block ange (ange without socket piece) or with hygienic
ttings, e.g. Neumo Biocontrol.
Mounting on socket
If the reective properties of the medium are good, you can mount
VEGAPULS 63 on a socket piece. You will nd recommended values
for socket heights in the following illustration. The socket end should
be smooth and burr-free, if possible also rounded. Then carry out a
false echo storage.

The mounting location of the radar sensor should be a place where no
other equipment or xtures cross the path of the microwave signals.
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 site that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage 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.
Small, inclined sheet metal baes above the installations scatter the
radar signals and prevent direct interfering reections.

If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfer-

ing reections from the agitators are saved with the blades in dierent
positions.
Fig. 13: Agitators
Through the action of lling, stirring and other processes in the vessel,
compact foams that considerably damp the emitted signals may form
on the product surface.
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.
As an alternative, sensors with guided microwave can be used. These
are unaected by foam generation and are best suited for such ap-
plications.
When using a surge pipe in a vessel, inuences from vessel installa-
tions and turbulences can be excluded. Under these prerequisites,
the measurement of products with low dielectric values (εr value
≥ 1.6) is possible. In very adhesive products, measurement in a surge
pipe is not recommended.

• Flanges are welded to the tube according to the orientation of the
polarisation level
• In case of a extension with a welding neck ange or pipe collar
as well as when a ball valve is used, the inner surfaces should be
aligned and accurately joined together
• Gap size with junctions ≤ 0.1 mm
• Do not weld through the pipe wall.The surge pipe must remain
smooth inside. Roughness and beads on the inside caused by
unintentional penetration should be removed since they cause
strong false echoes and encourage buildup
• Surge pipes must extend all the way down to the requested min.
level, as measurement is only possible within the tube
• Diameter of holes ≤ 5 mm, any number OK, on one side or com-
pletely through
• The antenna diameter of the sensor should correspond to the
inner diameter of the tube
• Diameter should be constant over the complete length
An alternative to measurement in a surge pipe is measurement in a
bypass tube outside of the vessel.
