3.2 Principle of operation
The radar sensor VEGAPULS WL 61 is the ideal sensor for all applications in the water and waste water industry. It is particularly suitable
for level measurement in water treatment, in pump stations as well as
storm water overow tanks, for ow measurement in open umes and
for gauge measurement.
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.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.

Polarisation plane
38061-EN-121011
VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire
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 strap, the polarisation can be used to reduce the eects of
false echoes.
The position of the polarisation level is marked by marking bars on the
instrument.

Installation position
When mounting the sensor, keep a distance of at least 200 mm
(7.874 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.
> 200 mm
(7.87

Fig. 15: 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.

Direct the sensor as perpendicular as possible to the product surface
to achieve optimum measurement results.
Fig. 19: Orientation of the sensor
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.

Foam generation
Flow measurement with

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.
The short examples give you introductory information on the ow

ensures the seal eect of the cable gland. If you are using cable with
a dierent diameter, exchange the seal or use a suitable cable gland.
We generally recommend the use of screened cable for HART multidrop mode.

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.

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:

7 Setup with PACTware
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.
Standard/Full version
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project conguration simplies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.
In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.
The standard version is available as a download under www.vega.
com/downloads and "Software". The full version is available on CD
from the agency serving you.
7.3 Saving the parameter adjustment data
We recommend documenting or saving the parameter adjustment
data via PACTware. That way the data are available for multiple use or
service purposes.

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
•
Control system with EDD
•
Indicating and adjustment module
•

Further echo curves: Up to 10 echo curves can be stored in a ring
buer in this memory section. Further echo curves are stored via:
PC with PACTware/DTM
•
Control system with EDD
•
9.3 Asset Management function
The instrument features self-monitoring and diagnostics according
to NE 107 and VDI/VDE 2650. In addition to the status messages in
the following tables there are more detailed error messages available
under the menu item "Diagnostics" via the indicating and adjustment
module, PACTware/DTM and EDD.
Status messages
The status messages are classied in the following categories:
Failure
•
Function check
•
Out of specication
•
Maintenance requirement
•
and explained by pictographs:
41 2 3
Fig. 29: 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.

signal
38061-EN-121011
VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire
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:
