3.2 Principle of operation
The VEGAPULS 62 radar sensor can be used in a wide variety of ap-
plications for continuous level measurement of liquids. It is suitable for
applications in storage vessels, reactors and process vessels, even
under extremely dicult process conditions.
Dependent on the application range, dierent versions are used:
• Antenna
– Small tanks and process vessels, measurement of virtually all
products: Horn antenna ø 40 mm
– Storage tanks and process vessels, measurement of products
such as solvents, hydrocarbons and fuels under extremely dif-
cult process conditions: Horn antenna ø 48 … 95 mm
– Products with low εr value with large measuring distances:
Parabolic antenna
• Electronics
– Products with an εr value ≥1.8: Standard electronics
– Products with an εr value < 1.8, ≥1.5; applications with very bad
reective properties: Electronics with increased sensitivity
The actual values that can be reached depend on the measurement
conditions, the antenna system or the standpipe or bypass.
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.

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
type label.
4.2 Mounting preparations - Horn antenna
The instrument is also available in versions with an antenna whose
diameter is larger than the process tting (thread, ange). In such
cases the antenna must be disconnected from the process tting
before mounting. Proceed as follows:
1. Loosen the hexagon socket screws (3) on the antenna socket
with an Allen wrench (size 3)
2. Remove the antenna (4)
Note:
The plastic cone may not be pulled out of the antenna socket.
3. Insert the antenna from below into the vessel socket and secure it
against falling o
4. Retighten the antenna with hexagon screws to the antenna
socket; torque max. 2.5 Nm (1.8 lbf ft)
Note:
The radar sensor with rinsing air connection or antenna extension
is provided with a notch on the antenna socket. This notch must be
aligned with the marking on the process tting (the marking species
the position of the polarisation plane of the radar signal).

4.4 Instructions for installation
The illustrations with the following mounting instructions show a radar
sensor with horn antenna. The mounting instructions apply analo-
gously also to the version with parabolic antenna.
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. By turning the instrument in the connection ange or
mounting boss, the polarisation can be used to reduce the eects of
false echoes.
The position of the polarisation plane is marked on the process tting
of the instrument.

When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the sensor is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can 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

can inuence the measuring result at close range.

If the medium has good reective properties, VEGAPULS 62 with
horn antenna can also be mounted on a longer socket piece. Rec-
ommended values for socket heights are specied in the following

Tip:
The instrument is also optionally available with an antenna extension.
The antenna length can be selected (either ex works or later) to allow
the antenna to protrude slightly out of the end of the mounting socket.
Due to the antenna extension however, disturbing reections are
generated in the close-up range. This can lead to an increase in the
required minimum distance, especially with poorly reecting media
such as plastic powder. In practice, a cleanly constructed mounting
socket, if necessary with rounded edges, introduces fewer disturbing
inuences than an antenna extension.
Align the sensor in liquids as vertical as possible to the product sur-
face to achieve optimum measurement.

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.
