3.2 Principle of operation
VEGASON 62 is an ultrasonic sensor for continuous level measurement. It is suitable for liquids and solids in virtually all industries,
particularly in the water and waste water industry.
Functional principle
28785-EN-130417
VEGASON 62 • Probus PA
The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reected by
7
3 Product description
product surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception
is proportional to the distance and hence the level. The determined
level is converted into an appropriate output signal and outputted as
measured value.
Power supply and bus
communication
GSD/EDD
Power supply via the Probus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Probus specication
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument prole of VEGASON 62 corresponds
to prole specication version 3.0.
The backlight of the display and adjustment module is powered by the
sensor. Prerequisite is a certain level of operating voltage.
The data for power supply are specied in chapter "Technical data".
The optional heating requires its own operating voltage. You can nd
details in the supplementary instructions manual "Heating for display
and adjustment module".
This function is generally not available for approved instruments.
The GSD (instrument master les) and bitmap les necessary for
planning your Probus-DP-(PA) communication network are available
from the download section on the VEGA homepage www.vega.com
under "Services-Downloads-Software-Probus". There you can
also nd the appropriate certicates. In a PDM environment, an EDD
(Electronic Device Description) is also required to enable the full
range of sensor functions (also available as a download).A CD with
the appropriate les can be ordered via e-mail under info@de.vega.

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process tting, are suitable for the existing process conditions, such
as 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
nameplate.
Installation position
Moisture
Measuring range
Select an installation position you can easily reach for mounting and
connecting as well as later retrotting of a display and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the display and adjustment module in four
dierent positions (each displaced by 90°).
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 o. 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.
Fig. 2: Measures against moisture penetration
The reference plane for the measuring range is the lower edge of the
transducer.
Make sure that a minimum distance from the reference plane - the
so-called dead band, in which measurement is not possible - is
maintained. The exact value of the dead band is stated in chapter
"Technical data".

3 Measuring range
Gauge pressure in the vessel does not inuence VEGASON 62. Low
pressure or vacuum does, however, damp the ultrasonic pulses. This
inuences the measuring result, particularly if the level is very low.
With pressures under -0.2 bar (-20 kPa) you should use a dierent
measuring principle, e.g. radar or guided microwave.
4.2 Mounting instructions
Screw VEGASON 62 into the mounting socket with an appropriate
spanner applied to the hexagon of the process tting. Max. torque see
chapter "Technical data".
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.

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").

> 200 mm
Fig. 5: Mounting on round vessel tops

2 Vessel center or symmetry axis
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.

Socket pieces should be dimensioned so that the lower end of the
transducer protrudes at least 10 mm (0.394 in) out of the socket.

If the reective properties of the medium are good, you can mount
VEGASON 62 on sockets which are higher than the length of the
transducer. You will nd recommended values for socket heights in the
following illustration. The socket end should be smooth and burr-free,
if possible also rounded. Carry out a false echo storage.

To reduce the min. distance to the medium, you can also mount VEGASON 62 with a beam deector. By doing this, it is possible to ll the
vessel nearly to maximum. Such an arrangement is suitable primarily
for open vessels such as e.g. overow basins.

Vessel installations
Agitators
The ultrasonic sensor should be installed at a location where no
installations cross the ultrasonic beam.
Vessel installations such as for example, ladders, limit switches, heat-
ing spirals, struts etc. can cause false echoes that interfere with the
useful echo. Make sure when planning your measuring site that the
ultrasonic signals have 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 or plastic baes above the installations
scatter the ultrasonic signals and avoid direct false echoes.

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 reections from the agitators are saved with the blades in dierent
positions.

Foam
Air turbulences
Do not mount the instruments in or above the lling stream. Make sure
that you detect the product surface, not the inowing product.
Fig.13:Inowingliquid
Through the action of lling, 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 sensor should be used
in a standpipe or, alternatively, the more suitable guided radar sensors (TDR) should be used.
Guided wave radar is unaected by foam generation and is particularly suitable for such applications.
If there are strong air currents in the vessel, e.g. due to strong winds
in outdoor installations or air turbulence, e.g. by cyclone extraction
you should mount VEGASON 62 in a standpipe or use a dierent
measuring principle, e.g. radar or guided radar (TDR).

Standpipe measurement
By using a standpipe (surge or bypass tube), the inuence of vessel
installations, foam generation and turbulence is excluded.
Standpipes must extend all the way down to the requested min. level,
as measurement is only possible within the tube.
