3.2 Principle of operation
The VEGAPULS 65 is a radar sensor for continuous measurement of
liquids under simple process conditions. It is particularly suitable for
level measurement in vessels with small process ttings and under
simple process conditions.
The instrument can be used with products with an ε
actually achievable value depends on the measuring conditions, the
antenna system, the standpipe or bypass.
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.
The instrument is powered via an integrated accumulator. This allows
operation of the instrument independently of the mains or a control
system. To achieve a longer battery lifetime, the instrument is preset
to HART multidrop. This puts a load of only 4 mA current on the accumulator.

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.

Suitability for the process
conditions
Sealing of the encapsulated antenna system
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 Instructions for installation
The ange screws must be tightened so that the PTFE washer of
the encapsulated antenna system seals eectively. You can nd the
required torque in the technical data.
You can counteract the material-induced tension loss with PTFE by
doing the following:
1. Make sure the number of ange screws corresponds to the number of ange holes
2. Use disc springs in addition to the ange screws for fastening the
ange
3. Tighten all screws with the torque stated in the technical data
Polarisation plane
14
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.

Installation position
When mounting the VEGAPULS 65, keep a distance of at least
500 mm (19.69 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 storage later with existing buildup.

Fig. 6: 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.

The active part of the antenna, i.e. the conical antenna part should
protrude completely out of the socket.
To meet the dierent socket dimensions, sensors for socket lengths
up to 50, 100 and 250 mm (2, 4, 10 in) are available.

Fig. 9: Recommended socket mounting
In case of very big socket diameters, the active antenna part can
be slightly recessed in the socket. The following rule applies to the
standard version of VEGAPULS 65: Socket diameter corresponds to
max. socket height.
Sensor orientation
Vessel installations
Align the sensor in liquids as vertical as possible to the product surface to achieve optimum measurement.
Fig. 10: Alignment in liquids
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.
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.

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. 12: Agitators
Through the action of lling, stirring and other processes in the vessel,
dense foams which considerably damp the emitted signals may form
on the product surface.
If foams are causing measurement errors, the biggest possible radar
antenna 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.

to ensure the optimum adjustment of the measurement. The procedure is described in the following.
Setup
Setup/Medium
Each medium has dierent reection properties. With liquids, further
interfering factors are uctuation product surface and foam generation. With bulk solids, these are dust generation, material cone and
additional echoes from the vessel wall.
To adapt the sensor to these dierent measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.

If a separation of liquids with dierent dielectric gure occurs in the
vessel, for example through condensation, the radar sensor can
detect under certain circumstances only the medium with the higher
dielectric gure. Keep in mind that layer interfaces can cause faulty
measurements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially designed for interface measurement.

Setup/Adjustment
Since a radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. For indication of
the real level, an allocation of the measured distance to the percentage height must be carried out.
To perform the adjustment, enter the distance with full and empty vessel, see the following example:

Fig. 19: Parameter adjustment example min./max. adjustment
1 Min. level = max. meas. distance
2 Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specications is always the seal surface of the thread or ange. By
means of these settings, the real level will be calculated.
The real product level during this adjustment is not important, because the min./max. adjustment is always carried out without changing the product level. These settings can be made ahead of time
without the instrument having to be installed.

VEGAPULS 65 • HART and accumulator pack
When non-contact level sensors are used, the measurement can be
inuenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The

higher the value, the more reliable the measurement. With a functioning measurement, the values are > 10 dB.
Diagnoses/Curve indication
The "Echo curve" shows the signal strength of the echoes over the
measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.
The "False signal suppression" displays the saved false echoes (see
menu "Additional settings") of the empty vessel with signal strength in
"dB" over the measuring range.
A comparison of echo curve and false signal suppression allows a
more accurate conclusion on measurement reliability. The selected
curve is continuously updated. With the [OK] key, a submenu with
zoom functions is opened:
"X-Zoom": Zoom function for the meas. distance

With the function "Echo curve memory" the echo curve can be saved
at the time of setup. This is generally recommended; for using the Asset Management functions it is absolutely necessary. If possible, the
curve should be saved with a low level in the vessel.
With the adjustment software PACTware and the PC, the high resolution echo curve can be displayed and used to recognize signal
changes over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.

False signal suppression
The following circumstances cause interfering reections and can
inuence the measurement:
High sockets
•
Vessel installations such as struts
•
Agitators
•
Buildup or welded joints on vessel walls
•
Note:
A false signal suppression detects, marks and saves these false signals so that they are no longer taken into account for level measurement.
This should be done with the low level so that all potential interfering
reections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and conrm
with [OK]. With [->] you have to select the menu item "False signal suppression" and conrm with [OK].
2. Conrm again with [OK].
3. Conrm again with [OK].
4. Conrm again with [OK] and enter the actual distance from the
sensor to the product surface.
5. All interfering signals in this section are detected by the sensor
and stored after conrming with [OK].
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as false
signal. The lling level would then no longer be detectable in this area.

6 Set up with the indicating and adjustment module
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal suppression":
The menu item "Delete" is used to completely delete an already created false signal suppression. This is useful if the saved false signal
suppression no longer matches the metrological conditions in the
vessel.
The menu item "Extend" is used to extend an already created false
signal suppression. This is useful if a false signal suppression was
carried out with a too high level and not all false signals could be detected. When selecting "Extend", the distance to the product surface
of the created false signal suppression is displayed. This value can
now be changed and the false signal suppression can be extended to
this range.
Additional adjustments/
Linearization curve
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindrical or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.
By activating the appropriate curve, the volume percentage of the
vessel is displayed correctly. If the volume should not be displayed in
percent but e.g. in l or kg, a scaling can be also set in the menu item
"Display".
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.
Caution:
Note the following if the instrument with corresponding approval is
used as part of an overll protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting the switching point on the level
switch.

7.2 Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the conguration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collection. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older rmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manual "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descriptions are available in the online help of PACTware and the DTMs.

9.1 Maintenance
If the device is used correctly, no maintenance is required in normal
operation.
9.2 Measured value and event memory
The instrument has several memories which are available for diagnosis purposes. The data remain even with voltage interruption.
Measured value memory
Event memory
Echo curve memory
Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:
Distance
•
Filling height
•
Percentage value
•
Lin. percent
•
Scaled
•
Current value
•
Meas. reliability
•
Electronics temperature
•
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
Modication of a parameter
•
Switching on and o times
•
Status messages (according to NE 107)
•
Error messages (according to NE 107)
•
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measurement conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:
PC with PACTware/DTM

•
and explained by pictographs:
4123
Fig. 22: Pictograms of the status messages
1 Failure - red
2 Function check - orange
3 Out of specication - yellow
4 Maintenance - blue
Failure: Due to a malfunction in the instrument, a failure message is
outputted.
This status message is always active. It cannot be deactivated by the
user.
Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Outofspecication: The measured value is unstable because the
instrument specication is exceeded (e.g. electronics temperature).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Maintenance: Due to external inuences, the instrument function
is limited. The measurement is aected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

The operator of the system is responsible for taking suitable measures to rectify faults.
The rst measures are:
Evaluation of fault messages, for example via the indicating and
•
adjustment module
Checking the output signal with 4 … 20 mA instruments
•
Treatment of measurement errors
•
Further comprehensive diagnostics options oer a PC with the software PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectied.
Connect a handmultimeter in the suitable measuring range according
to the wiring plan. The following table describes possible errors in the
current signal and helps to remove them:

are the normal call charges.
9.5 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
In Ex applications only one instrument and one electronics module
with respective Ex approval may be used.
If there is no electronics module available on site, the electronics
module can be ordered through the agency serving you. The electronics modules are adapted to the respective sensor and dier in signal
output or voltage supply.
The new electronics module must be loaded with the default settings
of the sensor. These are the options:
In the factory
•
Or on site by the user
•
In both cases, the serial number of the sensor is needed. The serial
numbers are stated on the type label of the instrument, on the inside
of the housing as well as on the delivery note.
When loading on site, rst of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics module").

10 Dismounting
10.1 Dismounting steps
Warning:
Before dismounting, be aware of dangerous process conditions such
as e.g. pressure in the vessel, high temperatures, corrosive or toxic
products etc.
Take note of chapters "Mounting" and "Connecting to power supply"
and carry out the listed steps in reverse order.
10.2 Disposal
The instrument consists of materials which can be recycled by specialised recycling companies. We use recyclable materials and have
designed the parts to be easily separable.
Materials: see chapter "Technical data"
For disposal or recycling within the European Union proceed according to the "Electronics recycling" and "Battery/Accumulator recycling"
below. Outside the European Union you should take note of the valid
national regulations.
Electronics recycling
This instrument is not subject to the WEEE directive 2002/96/EG and
the respective national laws. Therefore pass the instrument directly
on to a specialised recycling company and do not use the municipal
collecting points. These may be used only for privately used products
according to the WEEE directive.
Battery/accumulator recycling
Note:
The disposal is subject to the directive 2006/66/EG on batteries and
accumulators.
Batteries and accumulators contain some environmentally harmful but also some valuable raw materials that can be recycled. For
that reason batteries and accumulators must not be disposed of in
household waste.
All users are legally obligated to bring batteries to a suitable collection
point, e.g. public collection points. You can also return the batteries
and accumulators to us for correct disposal. Due to the very strict
transport regulations for lithium-based batteries/accumulators, this is
normally not a good idea because shipment is very expensive.
Proceed as follows to dismount the accumulator:
Unscrew the cover of the supply room
•
Loosen the plug connector
•
Loosen the xing screws
•
Pull out the complete insert by means of the plastic strap
•
Correct disposal avoids negative eects on humans and the environment and ensures recycling of useful raw materials.
