30511-EN-050914
OPTISOUND 3030 C - 4 … 20 mA/HART 7
OPTISOUND 3030 C is an ultrasonic sensor for continuous
level measurement. It is suitable for liquids and solids in
practically all industries.
Product description
Physical principle
Power supply
Packaging
The transducer of the ultrasonic sensor emits short ultrasonic
pulses to the measured product. These pulses are reflected by
the product surface and received by the transducer as echoes.
The running time of the ultrasonic 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.
Two-wire electronics 4 … 20 mA/HART for power supply and
measured value transmission on the same cable.
The power supply range can differ depending on the instrument version. The exact range is stated in the "Technical data"
in the "Supplement".
3.3 Adjustment
OPTISOUND 3030 C can be adjusted with two different
adjustment media:
l the indicating/adjustment module
l a HART handheld
The entered parameters are generally saved in OPTISOUND
3030 C, optionally also in the indicating/adjustment module.
3.4 Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc. to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly, 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
Mounting
Installation position
Moisture
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°).
Use the recommended cable (see chapter "Connecting to
power supply") and thighten the cable gland.
You can give your OPTISOUND 3030 C 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 mounting
outdoors, in areas where moisture is expected (e.g. by
cleaning processes) or on cooled or heated vessels.
Fig. 2: Measures against moisture penetration
Measuring range
The reference plane for the measuring range is the lower edge
of the transducer.
Make sure that a min. distance - the so called dead zone below the reference plane is maintained in which a measurement is not possible. The exact value of the dead zone is
stated in the Technical data in the Supplement.

Pressure/Vacuum
Gauge pressure in the vessel does not influence OPTISOUND
3030 C. Low pressure or vacuum, however, damp the
ultrasonic pulses. This influences the measuring result,

Mounting
particularly if the level is very low. With pressures under -
0.2 bar (-20 kPa) you should use a different measuring
principle, e.g. radar or guided radar (TDR).
4.2 Mounting information
Installation position
When mounting OPTISOUND 3030 C, keep a distance of at
least 200 mm (7.9 in) to the vessel wall. If the sensor is
installed in the center of dished or rounded vessel tops,
multiple echoes can arise. These can, however, be faded out
by an appropriate adjustment (see chapter "Setup").
If this distance cannot be maintained, a false echo storage
should be carried out during setup. This applies particularly if
buildup on the vessel wall is expected. In this case, we
recommend repeating the false echo storage later on with
existing buildup.

2 Vessel center or symmetry axis
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
Preferably the transducer should be mounted flush to the
vessel top.
If the reflective properties of the medium are good, you can
mount OPTISOUND 3030 C on a socket piece. You will find
recommended values of the 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.

Mounting
Sensor orientation
In liquids, direct the sensor as perpendicular as possible to the
product surface to achieve optimum measurement results.
Fig. 8: Orientation in liquids
To optimally align the sensor to solid products, a swivelling
holder (mounting strap) can be implemented.
Fig. 9: Orientation in solids
To reduce the min. distance to the medium, you can also
mount OPTISOUND 3030 C with a beam deflector. By doing
this, it is possible to fill the vessel nearly to maximum. This
arrangement is particularly suitable for open vessels such as e.
g. overflow basins.

Vessel installations
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, heating spirals, struts etc. can cause false echoes
superimposed on the useful echo. Make sure when planning
your measuring site that the ultrasonic signals have "free
access" to the measured product.
If there are 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 baffles above
the installations scatter the ultrasonic signals and avoid direct
false echoes.
Fig. 11: Cover smooth profiles with deflectors
Agitators
If there are agitators in the vessel, a false echo storage 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.

Inflowing material
Foam
Do not mount the instruments in or above the filling stream.
Make sure that you detect the product surface and not the
inflowing product.
Fig. 13: Inflowing liquid
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 sensor should
be used in a standpipe or, alternatively, the more suitable
guided radar sensors (TDR) should be used.
