3.2 Principle of operation
VEGAFLEX 62 is a level sensor with cable or rod probe for continuous
level measurement.
It is designed for industrial use in all areas of process technology and
can be used equally well in liquids or solids.
High frequency microwave pulses are guided along a steel rope or a
rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and
outputted as distance.

The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
Measured value transmission is carried out via the 4 … 20 mA/HART
output separate from power supply.
The background lighting of the indicating and adjustment module is
powered by the sensor. A certain level of operating voltage is required
for this. You can find the exact voltage specifications in chapter
"Technical data".
3.3 Operation
VEGAFLEX 62 can be adjusted with different adjustment media:
l with indicating and adjustment module
l with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
l with manufacturer-specific adjustment programs AMS™ or PDM
l With a HART handheld
3.4 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.

4.1 General instructions
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, 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" or on the
type label.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
In case of difficult installation conditions, the probe can be also
mounted laterally. For this purpose, adapt the rod with rod extensions
or bow-shaped segments.
The sensor must be readjusted to compensate the resulting running
time changes.

Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.
Use the hexagon for screwing in.
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.

Measuring range
Pressure
Mounting position
Fig. 4: Measures
The reference plane for the measuring range of the sensors is the
sealing surface of the thread or flange.
Keep in mind that a min. distance must be maintained below the
reference plane and possibly also at the end of the probe measurement in these areas is not possible (dead band). Keep in mind
that the cable length cannot be used all the way to the end because
measurement in the area of the gravity weight is not possible. These
dead bands are listed in chapter "Technical data". Keep in mind for the
adjustment that the default setting for the measuring range refers to
water.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.

4.2 Mounting instructions
Mount VEGAFLEX 62 in such a way that the distance to vessel
installations or to the vessel wall is at least 300 mm (12 in).
During operation, the probe must not touch any installations or the
vessel wall. If necessary, fasten the probe end.
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 bottom. When using the cable version,

keep in mind that measurement down to the tip of the probe is not
ble. The exact value of the min. distance (lower dead band) is
possi
stated in chapter "Technical data".
Vessel type
Fig. 5: Vessel
with conical bottom
Plastic vessel/Glass vessel
The guided microwave principle requires a metal surface on the
process fitting. Therefore use in plastic vessels etc. an instrument
version with flange (from DN 50) or place a metal sheet (ø > 200 mm/
8 in) beneath the process fitting when screwing it in.
Make sure that the plate has direct contact with the process fitting.
In bypass tubes of plastic, a metal screen must be provided on the
outside. You can glue metal foil, for example, on the outside along the
entire length of the tube. This metal screen must be connected to the
ground terminal on the instrument.
When installing rod or cable probes without metal vessel wall, e.g. in
plastic vessels, the measured value can be influenced by strong
electromagnetic fields (emitted interference according to EN 61326:
class A).
In this case, use a probe in coax version.

this is not possible, use short sockets with small diameter.
Higher sockets or sockets with a bigger diameter can generally be
used. They simply increase the upper dead band. Check if this is
relevant for your measurement.
In such cases, always carry out a gating out of false signals after
installation. You can find further information under "Setup procedure".

Standpipes or bypass
tubes
pes or bypass tubes are normally metal tubes with a diameter
Standpi
of 30 … 200 mm (1.18 … 7.87 in). In measurement technology such a
tube corresponds to a coax probe. It does not matter if the standpipe is
perforated or slotted for better mixing. Lateral inlets with bypass tubes
also do not influence the measurement.
Measuring probes can be mounted in bypass tubes up to DN 200.
If VEGAFLEX 62 is used in standpipes or bypass tubes, contact with
the tube wall should be avoided. We offer spacers as accessories for
fastening the probe in the middle of the tube.
Depending on the tube diameter or tube length, one or several spacers
can be mounted. With cable probes, the cable can also be strained to
avoid contact with the tube.
Keep in mind that buildup can form on the spacers. Strong buildup can
influence the measurement.
Microwaves can penetrate plastics. For process technical reasons,
plastic standpipes are problematic. If durability is no problem, then we
recommend the use of metal standpipes.
