Information:
The optional instrument features are described in the operating
instructions manual. The respective scope of delivery results from the
order specication.
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

ing in! Tightening can cause damage, 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
• When mounting horizontally, turn the housing so that the cable
gland or plug connector point downward
• 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.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Make sure that the degree of contamination specied in chapter
"Technical data" meets the existing ambient conditions.
Make sure before mounting that all parts of the instrument exposed to
the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Process tting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion and mechanical inuences
You can nd detailed information on the process conditions in chapter
"Technical data" as well as on the type label.
The instrument is suitable for standard and extended ambient condi-
tions acc. to IEC/EN 61010-1.

4.2 Mounting preparations
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; max. torque see chapter "Technical data"
Note:
The radar sensor with rinsing air connection or with antenna exten-
sion has a notch on the antenna socket for polarization. This notch
must be aligned with the marking on the process tting.

Caution:
A secure hold of the antenna is only ensured with the untwist guard.
The untwist guards inserted on site must hence be used again.
Depending on temperature range and antenna material, these are
spring rings according to DIN 217 or wedge lock washers according
to DIN 25 201.

Proceed as follows:
1. Clamp VEGAPULS 62 with the ange, e.g. in a bench vice
2. Hold the connection piece (1) with a wrench on the at surfaces
(width across ats 22 mm)
3. Loosen counter nut (3) completely with a wrench (width across
ats 36 mm) in the direction of the antenna
4. Loosen compression nut (2) completely with a wrench (width
across ats 41 mm) in the direction of the antenna
5. Remove the parabolic antenna (4) axially
6. Mount sensor ange on the adapter ange and fasten it tightly
7. Check if the O-ring seal is present on the connection piece and
make sure it is not damaged.
Note:
A damaged O-ring seal must be replaced: FKM (SHS FPM 70C3
GLT), FFKM (Kalrez 6375)
8. Remount the parabolic antenna (4)
9. Fasten compression nut (2) with a wrench (width across ats 41),
max. torque see chapter "Technical data"
10. Fasten counter nut (3) with a wrench (width across ats 36), max.
torque see chapter "Technical data"
Note:
On the version with rinsing air connection, make sure that the holes
in the antenna and in the process tting coincide. This ensures a suf-
cient air ow (the air is led through the holes to the feed system. A
rinsing of the whole parabolic antenna is not intended).

The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical wave compo-
nent. 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 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 maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup on
the vessel wall is expected. In such cases, we recommend repeating
the false signal suppression at a later date with existing buildup.
> 200 mm

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.
