Application area
3.2 Principle of operation
The VEGAPULS 61 is a radar sensor for continuous level measurement of liquids under simple process conditions.
The instrument is ideal also 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 overflow tanks, for
flow measurement in open flumes and for gauge measurement.
Functional principle
41714-EN-161104
Packaging
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected 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
based on ISO 4180.
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.

4Mounting
Screwing in
4.1 General instructions
On instruments with threaded process fitting, the hexagon must be
tightened with a suitable wrench. For the proper wrench size see
chapter "Dimensions".
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Protection against moisture
Protect your instrument against moisture ingress through the following
measures:
•
•
•
•
Use the recommended cable (see chapter "Connecting to power
supply")
Tighten the cable gland
When mounting horizontally, turn the housing so that the cable
gland points downward
Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where humidity is
expected (e.g. through cleaning processes) and on cooled or heated
vessels.
Suitability for the process Make sure that all parts of the instrument exposed to the process are
conditions
suitable for the existing process conditions.
These are mainly:
•
•
•
Active measuring component
Process fitting
Process seal
•
•
•
•
Process pressure
Process temperature
Chemical properties of the medium
Abrasion and mechanical influences
Process conditions are particularly:
You can find detailed information on the process conditions in chapter
"Technical data" as well as on the type label.
Cable glands
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
12
VEGAPULS 61 • 4 … 20 mA/HART - four-wire
41714-EN-161104
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection. The dust protection caps do
not provide sufficient protection against moisture.
4 Mounting
Prior to setup you have to replace these protective caps with approved cable glands or close the openings with suitable blind plugs.
4.2 Collar or adapter flange
For mounting the instrument on a socket, a combi compression flange
for DN 80 (ASME 3" or JIS 80) is also available for retro fitting. Optionally, the instrument can be also equipped with an adapter flange from
DN 100 (ASME 4" or JIS 100).
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar flange 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 specified
with the order.
You can find drawings of these mounting options in chapter "Dimensions".
Fig. 2: Flange mounting of the radar sensor
4.3 Mounting preparations, mounting strap
41714-EN-161104
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 effective 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 socket 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:

4.4 Mounting instructions
For tight installation of the version with plastic horn antenna with compression or adapter flange, the following conditions must be fulfilled:
1. Use suitable flat seal, e.g. of EPDM with Shore hardness 25 or 50
2. Make sure the number of flange screws corresponds to the number of flange holes
3. Tighten all screws with the torque stated in the technical data
Polarisation
The position of the polarisation is marked on the process fitting of the
instrument.
14
VEGAPULS 61 • 4 … 20 mA/HART - four-wire
41714-EN-161104
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical wave component. By turning the instrument in the connection flange or mounting
boss, the polarisation can be used to reduce the effects of false
echoes.

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 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
(7.87")
Fig. 6: Mounting of the radar sensor on round vessel tops
41714-EN-161104
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.

A corresponding collar flange for DN 80 (ASME 3" or JIS 80) as well
as a suitable adapter flange are available for mounting VEGAPULS
61.
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar flange 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 specified
with the order.
Information:
The mounting socket should be as short as possible and its end
rounded. This reduces false echoes from the vessel mounting socket.

Vessel installations
The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the radar 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 point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
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 baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
41714-EN-161104
Fig. 14: Cover flat, large-area profiles with deflectors
Agitators
If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interfering reflections from the agitators are saved with the blades in
different positions.

Fig. 15: Agitators
Foam generation
Through the action of filling, stirring and other processes in the vessel,
compact foam can form on the product surface, damping the emitted
signals considerably.
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 unaffected by foam generation and are best suited for such applications.
Measurement in a surge

4.5 Measurement setup - Pipes
By using a surge pipe in the vessel, the influence of vessel installations and turbulence can be excluded. Under these prerequisites, the
measurement of products with low dielectric values (εr value ≤ 1.6) is
possible.
Note the following illustrations and instructions for measurement in a
surge pipe.

Safety instructions
5.1 Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
•
•
The electrical connection must only be carried out by trained
personnel authorised by the plant operator.
If overvoltage surges are expected, overvoltage arresters should
be installed.
Note:
Install a separating facility for the instrument which is easy to access.
The separating facility must be marked for the instrument (IEC/
EN 61010).
Voltage supply via mains
voltage
In this case, the instrument is designed in protection class I. To maintain this protection class, it is absolutely necessary that the ground
conductor be connected to the internal ground terminal. Take note of
the national installation regulations.
Supply voltage and current signal are carried on separate connection
cables if reliable separation is required. The supply voltage range can
differ depending on the instrument version.
The data for power supply are specified in chapter "Technical data".
Voltage supply via low
voltage
In this case, the instrument is designed in protection class II. Generally connect the instrument to vessel ground (potential equalization)
or with plastic vessels to the next ground potential. For this purpose, a
ground terminal is located laterally on the instrument housing.
Connection cable
An approved, three-wire installation cable with PE conductor is
required for voltage supply with mains voltage.
The 4 … 20 mA current output is connected with standard two-wire
cable without screen. If electromagnetic interference is expected
which is above the test values of EN 61326-1 for industrial areas,
screened cable should be used.
Use cable with round cross section for instruments with housing and
cable gland. To ensure the seal effect of the cable gland (IP protection
rating), find out which cable outer diameter the cable gland is suitable
for.
Use a cable gland fitting the cable diameter.
41714-EN-161104
Cable glands
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
VEGAPULS 61 • 4 … 20 mA/HART - four-wire
27
5 Connecting to power supply
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with approved cable glands or close the openings with suitable blind plugs.
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".
Cable screening and
grounding
If screened cable is required, we recommend connecting the cable
screen on both ends to ground potential. In the sensor, the screen
must be connected directly to the internal ground terminal. The
ground terminal on the outside of the housing must be connected to
the ground potential (low impedance).
In Ex systems, the grounding is carried out according to the installation regulations.
In electroplating plants as well as plants for cathodic corrosion protection it must be taken into account that significant potential differences
exist. This can lead to unacceptably high currents in the cable screen
if it is grounded at both ends.
Information:
The metallic parts of the instrument (process fitting, sensor, concentric tube, etc.) are connected with the internal and external ground
terminal on the housing. This connection exists either directly via
the conductive metallic parts or, in case of instruments with external
electronics, via the screen of the special connection cable.
You can find specifications on the potential connections inside the
instrument in chapter "Technical data".
Connection technology
5.2Connecting
The voltage supply and signal output are connected via the springloaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turning it slightly to the left.

Setup - Medium
Letters from A … Z
Numbers from 0 … 9
Special characters +, -, /, -
Each medium has different reflection properties. With liquids, further
interfering factors are fluctuation 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 different measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.
Through this selection, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with poor reflective properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Setup - Application
In addition to the medium, also the application, i.e. the measuring site,
can influence the measurement.
With this menu item, the sensor can be adapted to the applications.
The adjustment possibilities depend on the selection "Liquid" or "Bulk
solid" under "Medium".
The following options are available when "Liquid" is selected:

curve at the time of setup. This is generally recommended, and it is
absolutely necessary to do this if you want to use the Asset Management functions. 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 during operation. In addition, the echo curve of setup can be
displayed in the echo curve window and compared with the current
echo curve.
Additional adjustments Instrument units
In this menu item you select the measured variable of the system and

Additional adjustments False signal suppression
The following circumstances cause interfering reflections and can
influence the measurement:
•
•
•
•
High sockets
Vessel internals 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 in the level
measurement.
This should be done with the lowest possible level so that all potential
interfering reflections can be detected.
Proceed as follows:
1. Select with [->] the menu item "False signal suppression" and
confirm with [OK].
41714-EN-161104

4. Confirm 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 confirming 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 a false
signal. The level would then no longer be detectable in this area.
If a false signal suppression has already been saved in the sensor,
the following menu window appears when selecting "False signal
suppression":
Delete: An already created false signal suppression will be completely deleted. This is useful if the saved false signal suppression no
longer matches the metrological conditions in the vessel.
Extend: is used to extend an already created false signal suppression. This is useful if a false signal suppression was carried out with
too high a 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
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. 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.

Further comprehensive diagnostics options are available with a PC
with PACTware and the suitable DTM. In many cases, the reasons can
be determined in this way and faults rectified.
Connect a multimeter in the suitable measuring range according to
the wiring plan. The following table describes possible errors in the
current signal and helps to eliminate them:

• Wherever the sensor displays a constant value, the reason could
also be the fault setting of the current output to "Hold value"
• If the level indication is too low, the reason could be a line resistance that is too high

English. The service itself is free of charge, the only costs involved 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 instruments and electronics modules with appropriate 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 differ 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, first of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics
module").
41714-EN-161104
Caution:
All user-specific settings must be entered again. Hence, you have to
carry out a new setup after the electronics exchange.
If you have stored the data of the parameter adjustment during the
first setup of the sensor, you can transfer these to the replacement
electronics module. A new setup is no more necessary.
