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.

Storage
38061-EN-121011

Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
Not in the open
•
Dry and dust free
•

•
Protected against solar radiation
•
Avoiding mechanical shock and vibration

The interface adapter VEGACONNECT enables the connection of
communication-capable instruments to the USB interface of a PC. For
parameter adjustment of these instruments, an adjustment software
such as PACTware with VEGA-DTM is required.
You can nd further information in the operating instructions "Interface adapter VEGACONNECT" (Document-ID 32628).
VEGADIS 62 is suitable for measured value indication and adjustment

4.1 General instructions
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 Mounting versions
Most simply mount the instrument via the straining clamp. For this
purpose, the connection cable is provided with a strain relief wire of
Kevlar.
In order to avoid faulty measured values, make sure that the sensor
does not oscillate.

Mounting bracket
38061-EN-121011
VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire
For a rigid mounting, a mounting bracket with opening for thread
G1½, e.g. from the VEGA product range, is recommended. The
mounting of the sensor in the bracket is carried out via a G1½ counter
nut of plastic. Take note of chapter "Mounting instructions" for the
distance to the wall.

Mounting strap
The optional mounting strap enables sensor mounting on e.g. a ceiling, wall or bracket. It is available in the following versions:
Length 300 mm for ceiling mounting
•
Length 170 mm for wall mounting
•
The instrument is normally mounted vertically on the ceiling.
This ensures swivelling of the sensor up to 180° for optimum orienta-
tion.

As an alternative, mounting can be carried out vertically on the wall.

Fig. 8: Vertical mounting on the wall via the mounting strap with length 170 mm
Some measuring points have only very little space between ceiling and water surface. In such cases, for example in closed storm
overow basins, horizontal mounting of the sensor is recommended.
The radar impulses must be directed via a 45° reector - for example
a stainless steel sheet - to the water surface.

Information:
With this mounting arrangement, the reference plane mentioned in
chapter "Technical data" no longer applies. There is an oset that
must be taken into account for the adjustment. Note the distance
measured at min. level with the reector, for example 2.5 m. Enter
this value as min. adjustment/measuring range begin. Determine the
dierence between the min. and max. level, for example 1 m. The distance for the max. adjustment results from 2.5 m - 1 m = 1.5 m. Enter
this value as max. adjustment/measuring range end.

Flange
For mounting the instrument on a socket or a manhole cover, an unassembled combination compression ange is optionally available for
DN 80 (ASME 3" or JIS 80), also as a retrotting part. As an alternative, the instrument can be already supplied with a tight, x-mounted
adapter ange from DN 100 (ASME 4" or JIS 100).
You can nd drawings of these mounting options in chapter "Dimen-sions".

4.3 Mounting preparations, mounting strap
The optional mounting strap is supplied unassembled. It must be
screwed to the sensor before setup with the attached screws. Max.
torque, see chapter "Technical data". Required tools: Allen wrench
size 4.
There are two dierent ways of screwing the strap to the sensor.
Depending on the selected method, the sensor can be rotated in
the strap innitely variable through 180° or in three steps 0°, 90° and
180°.

4.4 Instructions for installation
For tight installation of the version with plastic horn antenna with compression or adapter ange, the following conditions must be fullled:
1. Use suitable at seal, e.g. of EPDM with Shore hardness 25 or 50
2. Make sure the number of ange screws corresponds to the number of ange holes
3. Tighten all screws with the torque stated in the technical data
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.
