1 Introduction
1.1 Contents of the instruction manual
The Technical Information / Operating Instructions is
called TIB. It contains all necessary information for correct
- installation
- connection
- set-up
- optimization
of the pulse-echo-sensors VEGASON …. V… or pulseecho compact instrument VEGASON … K….
VEGA regularly revises the contents of TIBs as technical
improvements are made to the instruments.
1.2 Safety information
The described module must only be inserted and operated
as described in this TIB. Please note that other action can
cause damage for which VEGA does not take
responsibility.
2 Product description
2.1 Function and configuration
Function
The VEGASON … sensor systems or compact
instruments are used for continuous and non-contact level
measurement.
Short sound impulse packets are emitted by the
transducer of the pulse-echo sensor. The combined
emitter and receiver system detects the pulses reflected
by the product.
The running period of the ultrasonic pulses is directly proportional to the distance between sensor and measured
product.
The signal processing ECHOFOX
of signal analysis to process the reflected ultrasonic
pulses.
®
uses modern methods
The signal-to noise ratio is optimized by digital signal
processing methods with mathematic algorithms (DSP).
The automatic configuration of a user specific data base
enables an optimum adaption to the respective
application.
The use of fuzzy-logic for echo evaluation ensures a
reliable determination of the level. False echoes, e.g. from
stirrers or other installations are detected and are not
included in the generation of the measured value.
These measuring data are transmitted digitally to
respective signal conditioning instruments or processing
systems and processed.
The operation of the sensors is made via the signal
conditioning instrument VEGAMET or via a PC
(VEGACONNECT necessary).
Compact instruments are additionally equipped with an
integral output of the measuring data and make a current
output 0 … 20 mA available.
The operation of the compact instrument is only possible
with PC via VEGACONNECT.
Configuration
Flange version
The sensor or compact instruments consist of a housing,
integrated therein the above electronics and all required
terminals, a mounting flange and a transducer.
Housing, flange and transducer are designed acc. to the
type.
Separate version
The separate version consists of a housing with integral
electronics and all necessary terminal and mounting plate.
Transducer with mounting tube and connection cable as
separate modular unit. The transducers differ acc. to the
various types.

Therefore it is necessary to connect the computer via VEGACONNECT directly with the respective compact instruments.
A digital signal is superimposed to the current output. The adjustment of the sensor can be also carried out via the
current output. For indication and processing systems with an inner resistance of less than 100 Ohm a respective series
resistor must be connected for the time of adjustment.

3.1 Installation recommendations
relating to liquid tank / vessels
Installation under normal conditions
Flange version
Mounting on a very short, generally on a DIN-socket piece
available on the tank.
The max. filling of the tank depends on the min. distance
of the respective sensor or compact instrument.
Min. distance
Separate version
Mounting of the transducer in a very small hole (ø 35 mm)
in the tank ceiling. The mounting procedure can be
provided via an available access hatch.
Installation under special conditions
If the min. distance of the sensor is decreased, mounting
on a socket piece is necessary .
Generally the diameter of the socket piece should be as
large as possible and the socket length should be as short
as possible.
~45°

See the following schedule as general tube relating to the
dimensioning of the socket piece length to socket piece

Installation in open vessels
In most applications a separate version is recommended
for open vessels, i.e. mounting of the transducer to a
fastening bracket or in another fix position above the
vessel opening.
The max. filling of the vessel depends on the min. distance
of the respective sensor or compact instrument.
Due to variation possibilities of the transducer position, the
requested filling height can be ensured.
Information to socket piece / mounting
- In case of round top the sensor or the compact
instrument should be mounted on a socket piece
outside the center (mounting on half the range).

- The emitted sound impulse packets must not be
influenced by the filling stream.

Min. distance
- The socket piece must not be flooded by the measured
product.

- Chamfer the edges of the socket piece.
- There must be no weldment joints inside the socket
piece.

3.2 Installation recommendations
relating to solid silos
Installation under normal conditions
Flange version
Mounting on a very short, generally on a DIN-socket piece.
The socket piece must be directed to the center of the silo
outlet to ensure sufficient reflection in case of different
material angles of repose. The max. filling on the silo
depends on the min. distance of the respective sensor or
compact instrument.
Min. distance
Installation under special conditions
If the min. distance of the sensor is decreased, mounting
on a conical socket piece extension is necessary.
Information to socket piece / mounting
- Conical socket pieces acc. to drawing, i.e. conus
≥ 2x15°.
≥15° ≥15°
Min. distance
Separate version
In case of horizontal silo top the transducer of the separate
version in conjunction with a swivelling holder can be
easily and optimally directed to the center of the silo outlet.
The max. filling of the silo depends on the min. distance of
the respective sensor or compact instrument.
Min. distance
- Cylindrical socket pieces acc. to the values in the
schedule (see page 23) should only be used in silos
after consultance.
- Chamfer the edges of the socket piece.
- There must be no weldment joints inside the socket
piece.
Important:
The distance from the mounting position to the filling and
suction openings should be as large as possible.

The connection between echo sensor and signal
conditioning instrument or processing system can be
made with standard two-wire cable.
For installation with strong interference, screened cable is
recommended. Screening must only be earthed at one
end.
The two terminals marked with " " are connected in the
housing. Connect screening as marked and carry out
screening on the upper large terminal. Potential
equalization to the outer terminals.

5 Set-up
Set-up can be realized in different ways. Observe the
separate instruction for ECHOFOX
®
-sensors.
5.1 Sensor and signal conditioning
instrument (e.g. VEGAMET)
The set-up can be made directly via the operating
elements of the signal conditioning instrument or via a PC
(equipped with VVO-Software).
In this case the computer can be connected via
VEGACONNECT with the signal conditioning instrument
or directly with the sensor.
Attention, in case of Ex-sensors in the Ex-area,
VEGACONNECT must only be connected in the Ex-area
(e.g. signal conditioning instrument).
5.2 Sensor and processing system
(VEGALOG 571)
The set-up can be only made via PC (equipped with VVOSoftware).
The PC must be connected with a suitable central unit
(CPU) with the processing system VEGALOG 571
(interface RS 232).
5.3 Compact instrument
The PC (equipped with VVO-Software) must be directly
connected via VEGACONNECT with the compact
instrument or the current output.
