3.2 Principle of operation
The VEGAPULS 61 is a radar sensor for continuous level measurement of liquids under simple process conditions.
Dependent on the application range, dierent versions are used:
Level measurement of aggressive liquids in small vessels: encap-
•
sulated antenna system
Flow measurement in open umes or gauge measurement of bod-
•
ies of water: Plastic horn antenna
Products with an εr value ≥ 1.8: Standard electronics
•
Products with an εr value ≥ 1.5, < 1.8; applications with very poor
•
reective 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.
Functional principle
Packaging
36501-EN-121011
VEGAPULS 61 • Probus PA
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reected 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 appropriate 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
according to DIN EN 24180.

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.
Moisture
Suitability for the process
conditions
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 applies 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 specications in chapter "Technical data" and on the
type label.
4.2 Collaroradapterange
For mounting the instrument on a socket, a combi compression ange
for DN 80 (ASME 3" or JIS 80) is also available for retro tting. Optionally, the instrument can be also equipped with an adapter ange from
DN 100 (ASME 4" or JIS 100).
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the housing. With the aluminium double chamber housing, retroactive mounting in this way is not possible - the mounting type must be specied
with the order.
You can nd drawings of these mounting options in chapter "Dimen-
sions".

4.3 Mounting preparations, mounting strap
The mounting strap enables simple mounting on the vessel wall or
silo top. It is suitable for wall, ceiling or boom mounting. Especially in
open vessels this is a very easy and eective way to align the sensor
to the bulk solid surface.
The strap is supplied unassembled and must be screwed to the
sensor before setup with three hexagon screws M5 x 10 and spring
washers. Max. torque, see chapter "Technical data". Required tools:
Allen wrench size 4.
There are two ways to screw the strap onto the sensor. Depending
on the selected version, the sensors can be swivelled in the strap as
follows:
Single chamber housing
•
– Angle of inclination 180°, innitely variable
– Angle of inclination in three steps 0°, 90° and 180°
Double chamber housing
•
– Angle of inclination 90°, innitely variable
– Angle of inclination in two steps 0° and 90°

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 eects of
false echoes.
The position of the polarisation plane is marked on the process tting
of the instrument.

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 storage later with existing buildup.

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.

A corresponding collar ange for DN 80 (ASME 3" or JIS 80) as well
as a suitable adapter ange are available for mounting VEGAPULS
61.
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the housing. With the aluminium double chamber housing, retroactive mounting in this way is not possible - the mounting type must be specied
with the order.
Information:
The socket should be as short as possible and the socket end
rounded. Thus, false reections by the vessel socket are reduced.
Fig. 12: Recommended socket mounting
If the medium has good reective properties, VEGAPULS 61 can
also be mounted on a longer socket piece. Recommended values
for socket heights are specied in the following illustration. You must
carry out a false echo storage afterwards.

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 spirals, struts, etc., can cause false echoes and impair the useful echo.
VEGAPULS 61 • Probus PA
36501-EN-121011
4 Mounting
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 baes above the installations scatter the
radar signals and prevent direct interfering reections.
Fig.18:Coversmoothproleswithdeectors
Agitators
Foam generation
If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfering reections from the agitators are saved with the blades in dierent
positions.
Fig. 19: 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 unaected by foam generation and are best suited for such applications.

Measurement in a surge
pipe
When using a surge pipe in a vessel, inuences from vessel installations 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.

•
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.

36501-EN-121011
VEGAPULS 61 • Probus PA
The voltage supply is provided by a Probus DP /PA segment coupler.
The voltage supply range can dier depending on the instrument
version. You can nd the data for voltage supply in chapter "Technical
data".
Connection is made with screened cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent diameter or cross-section,
exchange the seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the
Probus specication. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.
You can nd detailed information of the cable specication, installation and topology in the "ProbusPA-UserandInstallationGuide-
line" on www.probus.com.
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technical data"
Make sure that the cable screening and ground is executed according to the Fielbus specication. If electromagnetic interference is
expected which is above the test values of EN 61326-1 for industrial
areas, we recommend to connect the cable screen on both ends to
ground potential.
With systems with potential equalisation, connect the cable screen
directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).
In systems without potential equalisation with cable screening on
both sides, connect the cable screen directly to ground potential at
the power supply unit and at the sensor. In the connection box or
T-distributor, the screen of the short stub to the sensor must not be
connected to ground potential or to another cable screen. The cable
screens to the power supply unit and to the next distributor must be
connected to each other and also connected to ground potential via a
