3.2Principle of operation
The radar sensor VEGAPULS WL 61 is particularly suitable for use in
pump stations and rain overflow basins,for flow measurement in open
flumes as well as for gauge measurement.The high housing protection
rating of the instrument allows outdoor mounting.
The antenna of the radar sensor emits short radar pulses with a
duration of approx.1ns.These pulses are reflected by the product
and received by the antenna as echoes.The running 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.
3.3Packaging,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 environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
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:
lNot in the open
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration
lStorage and transport temperature see chapter "Supplement -
Technical data -Ambient conditions"
lRelative humidity 20 …85 %

4Mounting
4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the antenna,seal and process fitting,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 find the specifications in chapter "Technical data"or on the
type label.
4.2Mounting versions
The most simple way to mount the instrument is via a straining clamp.
For this purpose,the connection cable is provided with a strain relief
rope of Kevlar.This rope must be anchored separately.
In order to avoid faulty measured values,make sure that the sensor
does not oscillate.

4Mounting
38062-EN-101005

For a rigid mounting,a mounting bracket with opening for thread
G1½A,e.g.from the VEGA product range,is recommended.The
mounting the sensor in the bracket is carried out via a G1½Acounter
nut of plastic.Take note of chapter 4.4"Mounting instructions"for the
distance to the wall.

(7.87 ")
Fig.3:Mounting via a mounting bracket
The optional mounting strap allows sensor mounting on a bracket or a
ceiling.Vertical mounting is the standard method.This allows rotating
the sensor for optimal alignment.
