3.2 Principle of operation
The VEGAPULS 67 is a radar sensor for continuous level measure-
ment of bulk solids under simple process conditions. It is suitable for
smaller silos and vessels.
The instrument is also suitable for applications in liquids.
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reected 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 appropri-
ate 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 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 in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.

4.1 General instructions
On instruments with threaded process tting, 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.
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 high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Make sure before mounting that all parts of the instrument exposed to
the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Process tting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion and mechanical inuences
You can nd detailed information on the process conditions in chapter
"Technical data" as well as on the type label.
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.
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 sucient protection against moisture.

4.2 Collaroradapterange
For mounting the instrument on a socket, a combi compression ange
for DN 80 (ASME 3" or JIS 80) is also available for retro tting. Option-
ally, the instrument can be also equipped with an adapter ange from
DN 100 (ASME 4" or JIS 100).
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the hous-
ing. With the aluminium double chamber housing, retroactive mount-

You can nd drawings of these mounting options in chapter "Dimen-
sions".

4.3 Mounting strap
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 eective 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:
• Single chamber housing
– Angle of inclination 180°, innitely variable
– Angle of inclination in three steps 0°, 90° and 180°
• Double chamber housing
– Angle of inclination 90°, innitely variable
– Angle of inclination in two steps 0° and 90°

4.4 Mounting instructions
For tight installation of the version with plastic horn antenna with com-
pression or adapter ange, the following conditions must be fullled:
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 num-
ber of ange holes
3. Tighten all screws with the torque stated in the technical data
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation is the direction of the electrical share. With
radar sensors, the polarisation can be used to reduce the eect of
false echoes considerably by turning the instrument in the connection
ange or mounting boss.
The position of the polarisation is marked on the instrument.

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.
Filling from the top: Mounting should not be too close to the inow-
ing material as the microwave signal will be interferred. The optimum
mounting position is on the opposite of the lling. To avoid strong
pollution, the distance to the lter or dust extraction must be as big as
possible.

Laterallling: With bulk solids silos with lateral pneumatic lling,
mounting should not be in the lling stream as the microwave signal
will be interferred. The optimum mounting position is next to the lling.
To avoid strong pollution, the distance to the lter or dust extraction
must be as big as possible.

A corresponding collar ange for DN 80 (ASME 3" or JIS 80) as well
as a suitable adapter ange are available for mounting VEGAPULS
67.
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the hous-
ing. With the aluminium double chamber housing, retroactive mount-
ing in this way is not possible - the mounting type must be specied
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.

If the medium has good reective properties, VEGAPULS 67 can
also be mounted on a longer socket piece. Recommended values
for socket heights are specied in the following illustration. You must
carry out a false echo storage afterwards.

The below charts specify the max. pipe socket length h depending on
the diameter d.

Tip:
In new facilities it is useful to incline the vessel socket in the direction
of the outlet. False reections from the vessel wall are thus reduced
and measurement all the way down to the bottom of the conical outlet
is possible.
