1 Product description
Product description
VEGAPULS series 40 sensors are a newly
developed generation of very compact, small
radar sensors for high resolution and accuracy. They are characterised by special
focusing features for level measurement in
narrow space applications. With modest
space requirements they were developed for
measuring distances of 0 … 4 m/10 m/20 m
and for standard applications such as storage vessels and buffer tanks as well as for
process tanks. With small housing dimensions and process fittings, the compact sensors monitor your levels at reasonable cost.
With the integrated display they enable high
precision level measurements and due to
their advantages, radar sensors have
increasingly become the standard solution
for many applications, even for those where it
was previously unthinkable due to high
costs.
VEGAPULS 40 radar sensors utilise two-wire
technology perfectly. The supply voltage and
the output signal are transmitted via one twowire cable. They provide a digital output
signal (VBUS or Profibus) or an analogue
4 … 20 mA signal as output or measuring
signal.
This operating instruction manual relates
to VEGAPULS 42, 44 and 45 sensors with
digital VBUS output signal (VEGA-Bus).
1.1 Function
Radio detecting and ranging: Radar.
VEGAPULS radar sensors are used for noncontact, continuous distance measurement.
The measured distance corresponds to a
filling height and is outputted as level.
Measuring principle:
emission – reflection – reception
Tiny 26 GHz radar signals are emitted from
the antenna of the radar sensor as short
pulses. The radar impulses reflected by the
sensor environment and the product are
received by the antenna as radar echoes.
The running period of the radar impulses
from emission to reception is proportional to
the distance and hence to the level.
Meas.
distance
emission - reflection - reception
The radar impulses are emitted by the antenna system as pulse packages with a
pulse duration of 1 ns and pulse intervals of
278 ns; this corresponds to a pulse package
frequency of 3.6 MHz. In the impulse intervals, the antenna system operates as receiver. Signal running periods of less than
one billionth of a second must be processed
and the echo image evaluated in a fraction of
a second.

Product description
VEGAPULS radar sensors can accomplish
this through a special time transformation
procedure which spreads out the more than
3.6 million echo images per second in a slowmotion picture, then freezes and processes
them.
tt
Time transformation
Hence, it is possible for the VEGAPULS radar sensors to process the slow-motion
pictures of the sensor environment precisely
and in detail in cycles of 0.5 to 1 second
without using time-consuming frequency
analysis (e.g. FMCW, required by other radar
techniques).
Virtually all products can be measured
Radar signals are physically similar to visible
light. According to the quantum theory they
propagate through empty space and are
therefore not dependent, like e.g. sound
waves, on a conductive medium. And like all
electromagnetic waves, they travel at the
speed of light.
The radar signals react to two primary
electrical properties:
- the electrical conductivity of a substance.
- the dielectric constant of a substance.
All products which are electrically conductive
or have a dielectric constant greater than ε
1.6 have sufficiently good reflection charac-

1.3 Adjustment
Each measuring situation is unique. For that
reason, every radar sensor needs some
basic information on the application and the
environment, e.g. which level means "empty"
and which level "full". Beside this "empty and
full adjustment", many other settings and
adjustments are possible with VEGAPULS
radar sensors.
Adjustment and parameter setting of the
radar sensors is done with
- the PC and the adjustment program VVO

2.3 Antennas
The antenna is the eye of the radar sensor. A
casual observer would never guess how
carefully the antenna geometry must be
adapted to the physical properties of electromagnetic fields. The geometrical form determines focal properties and sensitivity - the
same way it determines the sensitivity of a
unidirectional microphone.
For various application purposes, measurement conditions and process requirements,
series 40 sensors are available with three
antenna forms as VEGAPULS 42,
VEGAPULS 44 and VEGAPULS 45.
VEGAPULS 42 sensors are characterised by
1
G 1
/2 A or 11/2" NPT thread as process fitting.
These sensors are equipped as standard
versions with a ø 40 mm horn as antenna.
VEGAPULS 44 sensors are characterised by
a DIN or ANSI flanges as process fitting. In
standard version they are manufactured with
DN 50, 80, 100 and 150 as well as with ANSI
2", 3", 4" and 6". The bigger flanges come
equipped with respectively larger antenna
horns (ø 48, 75 and 95 mm).
Generally: The bigger the antenna horn, the
better the focusing characteristics, and the
better the antenna gain. This ensures that
even a weak product echo can be detected
reliably as level echo.
VEGAPULS 45 sensors are characterised by
integrated measuring tube. The measuring
tube serves the radar signals as a
waveguide in which no emitted energy is lost.
The complete emitted energy is returned as
reflection energy. Due to this, also products
with very weak reflection characteristics,
such as light petrol, liquid gas with
of 1.4 … 2.0 can be reliably detected.

Viscous or adhesive products cannot be

Horn antennas
Horn antennas focus the
radar signals very well.
Manufactured from 1.4435
(StSt) or Hastelloy C22, they
are very rugged, and both
physically and chemically
resistant. They are suitable
for pressures up to 40 bar
and for medium temperatures up to 150°C. The horn
VEGAPULS 42
diameters determine the
focusing of the radar signals. The antenna gain increases with increasing horn
diameter (40, 48, 75,
95 mm).
The antenna gain represents
the relation between
transmitted energy and
received echo energy.

Pipe antennas
Pipe antennas composed of horn antenna
and standpipe or bypass tube
Horn antennas on a standpipe or bypass tube form a
complete antenna system in
conjunction with a measuring
pipe (which must not be
perfectly straight, but can
also have bends). For the
radar signals, the measuring
pipe acts as a conductor.
The running time of the radar
signal changes in the pipe
and depends on the pipe
diameter. The sensor must
be therefore informed about
the tube inner diameter so
that the running time can be
taken into account and
precise level signals are
delivered. Pipe antennas are
best suited for turbulent
applications and products
with very low dielectric constant.
The antennas are
characterised by a very high
antenna gain. As a result,
high reliability is achieved
even with products having
very poor reflection properties.

Interfering reflections
Flat obstructions and struts cause large
interfering reflections. They reflect the radar
signal with high energy density.
Rounded profile interfering surfaces scatter
the radar signals in all directions and thus
cause interfering reflections of lower energy
density. Hence, they ar e less critical than
reflections from a flat surface.
If flat obstructions in the range of the radar
signals cannot be avoided, we recommend
diverting the interfering signals with a deflec-
tor. Through scattering, the interfering signals
will be low in amplitude and so diffuse that
they can be filtered out by the sensor.

Mounting and installation
Emission cone and interfering reflections
The radar signals are focused by the antenna system. The signals leave the antenna
in a conical path similar to the beam pattern
of a spotlight. The form and intensity of the
emission cone depend on the antenna used.
Any object in this beam cone causes a reflection of the radar signals. Within the first few
meters of the beam cone, tubes, struts or
other installations can interfere with the measurement. At a distance of 6 m, the false echo
of a strut has an amplitude nine times greater
than at a distance of 18 m.
At greater distances, the energy of the radar
signal distributes itself over a larger area,
thus causing weaker echoes from obstructing surfaces. The interfering signals are
therefore less critical than those at close
range.
If possible, orient the sensor axis perpendicularly to the product surface and avoid
vessel installations within the 100 % area of
the emission cone, e.g. tubes or struts.
The illustrations of the emission cones are
simplified and represent only the main beam
- a number of weaker beams also exist. Under difficult measuring conditions, the alignment of the antenna must be such that the
lowest possible false echo values appear.
Only giving attention to the size of the useful
echo is not always adequate when measuring conditions are unfavourable.
Optimum measuring conditions exist when
the emission cone reaches the measured
product perpendicularly and when the emission cone is free of obstructions.

3.2 Measurement of liquids
Flange antennas
In most cases, the mounting of radar sensors
is done on short DIN socket pieces. The
lower side of the instrument flange is the
reference plane for the measuring range. The
antenna must always protrude out of the
flange tube.
When the DIN socket piece is longer, please
make sure that the horn antenna is not cov-
ered completely by the socket. It is better if
the antenna protrudes slightly out of the
socket.

Dished tank ends can act as paraboloidal
reflectors. If the radar sensor is placed in the
focal point of the parabolic tank, the radar
sensor receives amplified false echoes. The
radar sensor should be mounted outside the
focal point. Parabolically amplified echoes
can be thereby avoided.

General instructions
Pipe antennas are preferred in vessels which
contain many installations, e.g. heating tubes,
heat exchangers or fast-running stirrers.
Measurement is then possible where the
product surface is very turbulent, and vessel
installations cannot cause false echoes.

Make sure the required upper vent hole in
the surge pipe is aligned with the sensor

As an alternative to a surge pipe in the ves-
sel, a pipe antenna system outside the ves-
sel in a bypass tube is also possible.
The surge and bypass tubes must generally
be made of metal. For plastic tubes, a
closed, conductive jacket is always required.
For metal tubes with plastic inner coating,
make sure that the thickness of the coating is
minimal (approx. 2 … 4 mm).
Align the sensor such that the type label lies
on one axis with the tube holes or the tube
connection openings. The polarisation of the
radar signal enables a considerably more
stable measurement with this alignment.

Extended bypass tube on a vessel with intense
product movements
For products with small dielectric constants
(< 4), a bypass tube longer than that required by the lower tube connection should
be used. Products with small dielectric constants are partly penetrated by the radar
signals, so that the tube bottom delivers a
stronger echo than the product (when the
bypass tube is nearly empty). As a result of
the extension of the lower tube end, sufficient
liquid will remain even when the vessel is
emptied.
With a liquid quantity of 300 … 800 mm in the
blind lower end of the tube, the portion of the
signal that penetrates the liquid and reflects
from the tube bottom is sufficiently damped the sensor can then easily distinguish it from
the echo of the liquid surface. If not enough
liquid remains, a deflection plate located at
the bottom of a vertical pipe can provide the
same function. It deflects the signal reflected
from the tube end sideways into the standard
tube opening.
Connections to the bypass tube
The connections to the bypass tubes must
be fashioned in such a way that only minimal
reflections are caused by the walls of the
connecting tubes. This is especially important
for the breather connection in the upper part
of the tube. Observe the following points:
• Use small openings for the connection.
• The diameter of the connecting tubes
should not exceed 1/3 of the bypass diameter.
• The tube connections must not protrude
into the bypass.
• Large welding beads in the tubes should
be avoided.
• Additional connections to the bypass tube
are more suitable if they lie on the same
plane as the upper and lower vessel connection (superimposed or displaced by
180°).

Conducting tube in existing surge or bypass tube
To increase the min. distance, the conducting
tube can protrude out of the surge or bypass
tube. For this purpose, a plain flange can be
welded at the required position on the outside of the extended conducting tube. In
both cases, an adequate vent hole must be
provided.

Use of conducting tubes
(VEGAPULS 44)
In case of very rough inner surfaces in existing bypass tubes (e.g. due to corrosion) or
in case of big connection openings as well as
bypass tubes with an inner diameter of more
than 100 mm, the use of a conducting tube in
the existing bypass tube is recommended.
This reduces the noise level and increases
reliability considerably. The flange of the
conducting tube can be easily mounted as a
sandwich flange between vessel and sensor
flange.

Seals on tube connections and tube extensions
Microwaves are very sensitive to gaps in
flange connections. If connections are made
without proper care, distinct false echoes as
well as increased signal noise can result.
Observe the following points:
• The seal used should correspond to the
tube inner diameter.
• If possible, conductive seals such as conductive PTFE or graphite should be used,
especially for thicker seals.
• Make sure that there are only a few seal
positions on a conducting tube.
Flange connections on bypass tubes
Adhesive products
For slightly adhesive products, choose a
surge pipe with e.g. a nominal width of
50 mm. VEGAPULS 42 and 44 radar sensors
with 26 GHz technology are relatively insensitive to buildup in the tube. Nevertheless,
buildup must not be allowed to plug up the
tube completely.
For adhesive products, the use of a DN 80 to
max. DN 100 stand/surge pipe can enable
measurement in spite of buildup. Products
that cause excessive buildup cannot be
measured in a standpipe.
VEGAPULS 45 with integrated measuring tube
The sensor version VEGAPULS 45 is especially developed for measuring tube applications and is supplied complete with a 27 mm
measuring tube. With a measuring tube
length up to 4 m, this sensor version is suitable e.g. for the use in existing standpipes.

VEGAPULS 45 sensors with integrated

fitting, make sure that the complete sensor,
i.e. also the sensor housing, turns when
screwing in. The sensor housing is fastened
with a clipped connection. This sensor housing must not be turned with respect to the
measuring tube or even loosened. Otherwise
the radar signal coupling would be
destroyed and the sensor would not function
proberly.
VEGAPULS 42, 44 and 45 – VBUS21
Mounting and installation
If you want to measure inhomogeneous products or stratified products in a surge pipe, it
must have holes, elongated holes or slots.
These openings ensure that the liquid is
mixed and corresponds to the liquid in the
vessel.
The more inhomogeneous the measured
product, the closer the openings should be
spaced.
Due to radar signal polarisation, the holes or
slots must be positioned in two rows offset
by 180°. The radar sensor must then be
mounted so that the type label of the sensor
is aligned with the rows of holes.

Guidelines for standpipe construction
Radar sensors for measurement on surge or
bypass pipes are used with G 1½ A
screwed-on antenna or flange sizes DN 50,
DN 80, DN 100 and DN 150. The radar
sensor with a DN 50 flange is only a
functional measuring system in conjunction
with a measuring tube.
On the left you see the constructional features of a measuring pipe (surge or bypass
tube) as exemplified by a sensor with DN 50
flange.
The measuring pipe must be smooth inside
(average surface quality Rz ≤ 30). Use stain-
less steel tubing (drawn or welded lengthwise) for construction of the measuring pipe.
Extend the measuring pipe to the required
length with welding neck flanges or with connecting sleeves. Make sure that no shoulders
or projections are created during welding.
Before welding, join pipe and flange with their
inner surfaces flush and exactly fitting.
Avoid welding through the pipe wall. The pipe
must remain smooth inside. Roughness or
welding beads on the inner surfaces must be
carefully removed and burnished, as they
cause false echoes and encourage product
adhesion.
On the following page you will see the
constructional features of a measuring pipe
as exemplified by a sensor with DN 100
flange.
If the vessel contains agitated products,
fasten the measuring pipe to the vessel bottom. Provide additional fastenings for longer
measuring pipes.

When measuring products with lower dielectric values (< 4), a part of the radar signal
penetrates the medium. If the vessel is nearly
empty, an echo is generated by the medium
and the vessel bottom. In some cases, the
vessel bottom generates a stronger signal
echo than the product surface. With a deflector on the measuring pipe end, the radar
signals are scattered. In nearly empty vessels and products with low dielectric value,
the medium then generates a stronger echo
than the vessel bottom.
Thanks to the deflector, only the useful signal
is received in a nearly empty vessel - the

3.4 False echoes
The mounting location of the radar sensor
must be selected such that no installations or
inflowing material cross the radar impulses.
The following examples and instructions
show the most frequent measuring problems
and how to avoid them.
Vessel protrusions
Vessel forms with flat protrusions can, due to
their strong false echoes, greatly effect the
measurement. Shields above these flat protrusions scatter the false echoes and guarantee a reliable measurement.
CorrectWrong
Vessel protrusions (slope)
Intake pipes, i.e. for the mixing of materials with a flat surface directed towards the sensor - should be covered with a sloping shield
that will scatter false echoes.
Vessel installations
Vessel installations such as, for example, a
ladder, often cause false echoes. Make sure
when planning your measuring location that
the radar signals have free access to the
measured product.
CorrectWrong
Ladder
Vessel installations
Ladder
Struts
Struts, like other vessel installations, can
cause strong false echoes superimposed on
the useful echoes. Small shields effectively
hinder a direct false echo reflection. These
false echoes are scattered and diffused in
the area and are then filtered out as "echo
noise" by the measuring electronics.

product surface and not the inflowing material.
Correct

Buildup
If the sensor is mounted too close to the
vessel wall, buildup and adhesions of the
measured product to the vessel wall will
cause false echoes. Position the sensor at a
sufficient distance from the vessel wall.
Please also note chapter "3.1 General installation instructions".
CorrectWrong
Strong product movements
Strong turbulences in the vessel, e.g. caused
by stirrers or strong chemical reactions, can
seriously interfere with the measurement. A
surge or bypass tube (figure) allows, provided the product causes no buildup in the
tube, a reliable measurement even with
turbulences in the vessel.

Sensor too close to the vessel wall
If the radar sensor is mounted too close to
the vessel wall, strong false echoes can be
caused. Buildup, rivets, screws or weld joints
superimpose their echoes onto the product
or useful echo. Please ensure sufficient distance from the sensor to the vessel wall.
Foam generation
Conductive foam is penetrated by the radar
signals to different depths and generates a
number of single (bubble) echoes. The signals in the foam are also damped, like heat
radiation that tries to penetrate styrofoam.
Thick, dense, creamy foam, and especially
conductive foam, on the product surface can
cause incorrect measurements.
conductive

Liquid
In case of good reflection conditions (liquids

without vessel installations), we recommend
selecting the sensor distance so that there is
no vessel wall within the inner emission cone.
For products in less favourable reflection
environments, it is a good idea to also keep
the outer emission cone free of interfering
installations. Note chapter "3.1 General installation instructions".
Take measures to avoid foam, measure in a
bypass tube or use a different measuring
technology, e.g. capacitive electrodes or
hydrostatic pressure transmitters.
In many cases, VEGAPULS 54 radar sensors
with 5.8 GHz operating frequency achieve
considerably better and more reliable measuring results in foam applications than type
40 sensors with 26 GHz technology.

Wrong polarisation direction
When measuring in a surge pipe, especially if
there are holes or slots for mixing in the tube,
it is important that the radar sensor is aligned
with the rows of holes.
The two rows of holes (displaced by 180°) of
the measuring tube must be in one plane with
the polarisation direction of the radar signals.
The polarisation direction is always in the

4.4 Configuration of measuring
systems
A measuring system consists of one sensor
and one processing unit. The processing unit
(VEGAMET signal conditioning instrument or
VEGALOG processing system) evaluates the
level-proportional, digital measuring signals
in a number of processing routines and outputs the levels as individual current, voltage
or switching signals.
Two sensors can be connected via one twowire cable to VEGAMET signal conditioning
instrument. Up to 255 sensors can be connected to the VEGALOG 571 processing
system. 15 sensors (loop powered) can be
connected on one two-wire cable.
Beside the output of the level in percent,
cubic meter or other physical units, as current, voltage or switching signal (relay or
transistor), the levels can also be processed
by linked processing algorithms. Scaling,
linearisation, calculation of linearisation
curves, differential generation, addition or
tendency processing are an integral part of
the VEGALOG processing systems and
VEGAMET and are easy to implement via the
menu selection.
Ex
Series 40 sensors with VBUS signal require
for operation in Ex areas the Ex separator
VEGATRENN 548V Ex, providing intrinsically
safe Ex circuits to the sensors. Up to nine
sensors (in groups of three sensors) can be
connected to the Ex separator VEGATRENN
548V Ex.
Connection cable
Sensor wiring should be looped in screened
cables. Ground the cable screens on the
processing system, or better, on the sensor.
We recommend grounding the cable screens
on both ends. However, make sure that no
earth compensation currents flow via the
screens. When earthing on both ends, it is
possible to connect the cable shield on one
earth side (e.g. in the switching cabinet) via a
capacitor (e.g. 10 nF; 1500 V).

5 Setup
Setup
5.1 Adjustment structure
The radar sensors can be operated
- with the PC (adjustment program VVO,
version ≥ 2.70)
- with the adjustment module MINICOM
- with the VEGAMET signal conditioning
instrument.
The adjustment is always possible with one
adjustment instrument at once.
Adjustment with the PC
The PC with the adjustment program VVO
(VEGA Visual Operating) in version ≥ 2.70
can be connected to:
- the sensor
- the signal cable
- the VEGAMET 514V, 515V signal conditioning instrument
- the VEGALOG 571 processing system.
With the adjustment program VVOon the PC,
you can adjust the radar sensors very easily.
A digital adjustment signal is herewith
superimposed to the signal and supply
cable. By this means, the adjustment can be
made directly on the sensor, on any position
of the signal cable or on the VEGAMET or
VEGALOG processing system.
Note:
Make sure that for adjustment of VEGAPULS
42, 44 and 45 sensors, the adjustment program VVO in version 2.70 or higher is
installed.
PC directly on the sensor
Insert VEGACONNECT into the communication sockets of an individual sensor. Only
sensor-relevant adjustment options such as
e.g., sensor optimisation on the affected
sensor, are adjustable. Other sensors and
VEGAMET are then not adjustable. This is
due to an adjustment hierarchy beginning
with VEGAMET or VEGALOG and ending
with the sensor.
PC on the signal cable
Only the sensor-relevant adjustment options
of sensors connected to the signal cable are
adjustable on the signal cable. However, not
available are the configuration and measured
data processing functions of VEGAMET or
VEGALOG.
Note:
The adjustment with the "PC on the signal
cable" and with the "PC directly on the sensor" is described in chapter "5.2 Adjustment
with the PC on the signal conditioning instrument". For this reason, adjustment with the
PC when connected directly to the sensor or
the signal cable is not shown separately.
Adjustment with the PC on the VEGAMET
signal conditioning instrument or on the
VEGALOG processing system
The PC communicates via the interface converter VEGACONNECT 2 with the signal
conditioning instrument or via the standard
RS 232 interface cable with the VEGALOG
processing system and all sensors connected to VEGAMET or VEGALOG. If you
connect the PC to the processing system or
the signal conditioning instrument, besides
the connected sensors, also the processing
system or the signal conditioning instrument
is adjustable.
Adjustment with the VEGAMET signal
conditioning instrument
Sensor and VEGAMET signal conditioning
instrument can be operated with the 6 key
adjustment field of the signal conditioning
instrument just like with the adjustment program VVO. The scope of the adjustment
functions is the same as with VVO on the PC.
42VEGAPULS 42, 44 and 45 – VBUS
Setup
Adjustment with the adjustment module
MINICOM
With the adjustment module MINICOM you
adjust the individual sensor directly in the
sensor or in the external indicating instrument
VEGADIS 50. The adjustment module
MINICOM with the 6 key adjustment field with
text display enables the parameter adjustment of the sensor with an array of functions
comparable to the adjustment program VVO
or the VEGAMET signal conditioning instrument, but not the configuration of the measuring system.
Adjustment of the signal conditioning instrument is only possible with the adjustment
program VVO or the 6 key adjustment field
on the instrument itself.
5.2 Adjustment with the PC on the
signal conditioning instrument
To connect the PC to the signal conditioning
instrument, the interface converter
VEGACONNECT is required. The PC communicates via the interface converter with the
signal conditioning instrument and the connected sensors.
In the following setup and adjustment instructions you will find information on the following
topics and adjustment points:
•

Note:
Keep in mind that you first have to log in a
sensor in the configuration menu before you
can continue with the parameter setting and,
if necessary, carry out adjustments in the
menu "
Sensor optimisation
VEGAPULS 42, 44 and 45 – VBUS43
".
Adjustment with the PC on the signal conditioning instrument
Beside the measured values, adjustment
signals are also transmitted digitally via the
signal and supply cable between sensor and
VEGAMET. The adjustment program VVO
can then communicate with VEGAMET and all
connected sensors. In chapter "4.4 Configuration of measuring systems", connection of
the PC to different sensor arrangements is
shown.
Before starting setup:
Do not be confused by the many pictures,
adjustment steps and menus on the following
pages. Just carry out the setup with the PC
step by step and you will soon no longer
need the following instructions. Actions, like
entering a value or making a choice, are
indicated in the following by a large black
dot, like this:
• Choose …
• Start …
• Click to …
• Connect the standard output of your PC by
the standard RS 232 interlink cable to
VEGALOG.
• Now switch on the power supply of the
processing system.
By this convention, the actions to be carried
out are clearly separated from supplementary information in the following adjustment
instructions.
Start now:
• Connect the standard plug of
VEGACONNECT 2 (9-pole) to the interface
COM 1 or COM 2 of your PC.
• Insert the two small pin plugs of
VEGACONNECT 2 into the CONNECT
socket on the front of the signal conditioning instrument.
• Now switch on the power supply of the
signal conditioning instrument.
Usually after approx. 1 … 2 minutes (selftest) the measuring system is operating and
displaying the measured value.
• Now start the adjustment software VVO on
your PC.
• Choose with the arrow keys or the mouse
the item "
Planning
" and click to "OK".
You are asked for user identification.
• Enter under name "VEGA".
• Also enter "VEGA" under password.
You are asked for the kind of sensor connection or if you want to carry out a virtual
adjustment.
• Choose "

Configuration
During the setup of the measuring system
you are confronted with two terms: "Configuration" and "Parameter adjustment". The
meas. system is first set up with a configuration and then with a parameter adjustment.

No matter whether you set up a measuring
system (consisting of sensor and VEGAMET
signal conditioning instrument or VEGALOG
processing system) with the adjustment
software VVO or with the signal conditioning
instrument, the adjustment procedure is
always the same:
- first of all in the menu "
Configuration
", you
create a measurement loop
- then configure a measurement loop
- in the menu "
Instrument data
" you carry out
the parameter adjustment of the sensor.
Configuration
The term "Configuration" means the basic
adjustments of VEGAMET. You inform
VEGAMET about the application (level measurement, gauge, distance …), the measurement loop name and the input channel. The
configuration represents an electronic wiring
and labelling of your VEGAMET or, in other
words, telling the system which sensor for
what application and where.
Parameter adjustment
After the configuration, you carry out the
parameter adjustment for each individual
sensor. This means adjusting the sensors to
the respective operating range and adapting
them to the specific application. You infor m
the sensor which product distance (which
level) is "empty" and which "full". This is called
adjustment. Here you choose which physical
quantity (volume, mass) and unit of
measurement (m
3
, gal, liters …) the adjusted
measured value should be outputted in. In
the submenu "Sensor optimisation", you
inform the sensor electronics about the actual
environment, such as e.g. quick changes of
the measured value, foam generation, gas
stratification, solid or liquid.

level. 1.27 m meas. distance corresponds to
100 % level. The measuring span is therefore
4.58 m (5.85 m – 1.27 m = 4.58 m).
The percentage value of 95.79 % means that
now 4.387 m of the adjusted measuring
span (4.58 m) have been reached:
4.58 • 0.9579 = 4.387 m.
The distance (product distance) outputted
by the sensor, in case you have chosen
"
distance
" as output parameter, is then:
5.85 – (4.58 • 0.9579) = 1.463 m.
If the index markers or value pairs of your
vessel are not known, you have to define the
linearisation curve by incremental filling or
calculate it with the vessel calculation program of VVO.
Defining the linearisation curve by incremental filling
In the characteristics of the example, you see
four index markers or value pairs. There is
always a linear interpolation between the
index markers. The example vessel consists
of three cylindrical segments of different
height and diameter. The middle segment
has a considerably smaller diameter.

Outputs
Configure outputs
VEGAMET 514V/515V is provided with current, voltage and switching outputs.
VEGALOG enables additional transistor
outputs. Before an adjustment signal is set
(parameter adjustment), it must be assigned
to a particular (configurate), because inputs
and outputs are independent components.
For example, a sensor signal can be
assigned to several current or voltage outputs (three per VEGAMET) and the parameter adjustment for each output can be
different (0 … 20 mA; 20 … 0 mA etc.). Relay
switching functions, after being assigned to a
sensor signal, are adjusted during the parameter adjustment, for example with certain
switching routines (dry run protection, overfill
protection, switching points, switching hysteresis).
In the following, the configuration of outputs
with the PC is described, which can be naturally carried out also with the 6 adjustment
keys on the VEGAMET 514V, 515V and 614V

5. Measurement in a standpipe
This adjustment is only necessary if the
sensor is mounted on a standpipe (surge or
bypass tube). When measuring in a
standpipe, the distance must be sounded
and the measured value display (can deviate
a few percentages from the sounded value)
must be corrected according to the
sounding. Then the sensor corrects future
running time shifts of the radar signal in the
standpipe and displays the correct level in
the standpipe (meas. tube).
6. Operating range
Without special adjustment, the operating
range corresponds to the measuring range.
The measuring range has already been adjusted with the min./max. adjustment. Generally it is useful to choose a slightly bigger
(approx. 5 %) operating range than measuring range.
Example:
Min./max. adjustment: 0.500 … 3.500 m;
adjust operating range to approx.
0.400 … 3.600 m.

an internal database. The sensor electronics
treats these (false) echoes differently from
the useful echoes and filters them out.
The menu item "Signal conditioning" in the

5.4 Adjustment with the PC on
VEGALOG
For connection of the PC to the VEGALOG
processing system, a standard RS 232 DTEDTE (Data Terminal Equipment) interface
cable is required. Connect the PC with the
cable to the processing system.

Beside the measured values, adjustment
signals are also transmitted digitally between
sensor and processing system via the signal
and supply cable. The adjustment program
VVO can then communicate with the
processing system and all connected sensors. In chapter "4.4 Configuration of measuring systems" the connection of the PC to the
different configurations is shown.
The individual adjustment steps are marked
in the following with a dot.
Example:
• Choose …
• Start …
• Click to …
The first steps of the setup with the PC in
conjunction with the VEGALOG processing
system correspond to the adjustment in
chapter "5.3 Adjustment with VEGAMET or
MINICOM".
• Connect the standard interface of your PC
with the standard RS 232 interlink cable (9pole) to the VEGALOG processing system.
• Now switch on the power supply of the
processing system.
After approx. 1 … 2 minutes (self-test) the
measuring system, consisting of processing
system and sensors, is in operating condition
and the sensors display measured values.
• Now start the adjustment software VVO on
your PC.
• Choose with the arrow keys or the mouse
the item "
Planning
" on the entrance screen
and click to "OK".
In the next window, you are asked for the
user identification.
• Enter under name "VEGA".
• Also enter "VEGA" under password.
The adjustment program VEGA Visual Operating (VVO), called in the following VVO, gets
into contact with the connected sensor and
indicates after a few seconds if and with
which sensor a connection exists.
Note:
If you make no connection with the sensor,
check the following:
- Is the processing system being supplied
with supply voltage?
- Did you inadvertently use a wrong RS 232
cable instead of the VEGA RS 232 connection cable?
76VEGAPULS 42, 44 and 45 – VBUS
Adjustment with the PC on VEGALOG
If VVO (adjustment software) gets in contact
with the processing system for the first time,
you will be asked if you want to transfer the
data from the processing system to the PC.
• Click to "
If you have connected the VVO to a
VEGALOG from which data has already been
saved, you are asked if the saved data
should be transferred from the PC to
VEGALOG or the data from VEGALOG to the
PC.

Configuration
The adjustment of a radar sensor with the PC
on a VEGALOG generally corresponds to the
adjustment of a radar sensor on the signal
conditioning instrument, as in chapter "5.2
Adjustment with the PC on VEGAMET".
The only difference are the increased configuration requirements of VEGALOG. A
number of possible sensor inputs and signal
outputs as well as different processing
routines must be assigned. First of all, you
must define where and what processing
which sensor (input) does.
Configuration info
• Choose the menu "

Configuration/Measur-
".
No matter whether you set up a measuring
system (unit consisting of sensor and
VEGAMET signal conditioning instrument or
VEGALOG processing system) with the
adjustment software VVO or with the signal
conditioning instrument, the adjustment procedure is always the same:
- first of all, create a measurement loop and
configure a measuring system in the menu

- carry out the parameter adjustment of the
sensor in the menu "

Diagnosis
6.1 Simulation
To simulate a certain filling, you can call up
the function "Simulation" on the adjustment
module MINICOM, in the software program
VVO or on the signal conditioning instrument.
You simulate a vessel filling and thereby a
certain sensor current. Please note that connected instruments, such as e.g. a PLC react
according to their adjustments and will probably activate alarms or system functions.
Simulation with VVO
If you start the simulation mode with the adjustment program VVO on the PC, the simulated level is outputted until you quit the
simulation mode.
Simulation with VEGAMET
If you call up the simulation mode with the
adjustment keys on the signal conditioning
instrument, 15 minutes after the last adjustment the signal conditioning instrument returns to standard operating condition.
Simulation with MINICOM
If you start the simulation mode on the adjustment module MINICOM, the sensor returns to
standard operating mode after one hour.
