3.2Principle of operation
The VEGAPULS 66 is a radar sensor for continuous level measure-
ment of liquids under difficult process conditions.It is suitable for
applications in storage tanks,process vessels or standpipes.The
instrument can be used universally thanks to the different antenna
versions.
The version with horn antenna is particularly suitable for the
measurement of liquids and bulk solids under extremely difficult
process conditions such as buildup,condensation and foam gener-
ation as well as strong product movement.
In the version without antenna,the antenna system is formed in
conjunction with a measuring tube (surge or bypass tube). This version
is particularly suitable for measurement of solvents and liquid gases.
The instrument can be used with products with an ε
r
value ≥1.8.The
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.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.

4Mounting
4.1General instructions
With instruments with threaded process fitting,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.
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 off.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
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"and on the
type label.
4.2Instructions for installation
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 flange or
mounting boss,the polarisation can be used to reduce the effects of
false echoes.

When mounting the VEGAPULS 66,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.

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.

If the socket height cannot be maintained,an antenna extension will be
necessary.This prevents from false reflections of the socket piece.

Tip:
VEGAPULS 66 is optionally also available with antenna extension.The
antenna length can thus be selected such that the antenna end
protrudes 10 mm (0.4in)out of the socket.
Align the sensor in liquids as vertical as possible to the product surface
to achieve optimum measurement.
Fig.8:Alignment in liquids
The mounting location of the radar sensor should be a place where no
other equipment or fixtures 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 baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
Fig.9:Cover smooth profiles with deflectors
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
reflections from the agitators are saved with the blades in different
positions.
Fig.10:Agitators
Through the action of filling,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 unaffected by foam generation and are best suited for such
applications.
