Measurement technology for a demanding industry
housing versions in plastic, aluminium and
stainless steel
all sensors are available in Intrinsically safe, or Explosion
proof housings
VEGA instruments are appropriate for SIL rated applications
dust approval ratings available
operating temperatures up to 400°C (752°F)
highly corrosion resistant materials
The environment and recycling industry sets high
demands on housings, electronics and sensor
technologies. No problem for VEGA – because all
components can be adapted to the required process
conditions.
A rugged housing is crucial for protection and high
mechanical stability. Depending on the model type,
sensors and antennas are able to withstand temperatures
up to 400°C (752°F) and are resistant to acids and alkalis.
The basis for this is the use of high-resistance materials
such as PTFE, Hastelloy, tantalum and enamel.
Under rigorous conditions
VEGA offers a suitable process connection for every
vessel and pipeline. Be it a simple storage tank or a
complex reaction vessel with heating coils and agitators –
thanks to the extensive range of physical measuring
principles virtually any application problem can be solved.
Connections to suit your process

In the area of landfill and special waste treatment, vessels
are alternately filled with products having varying
properties. Quite often the materials to be processed and
the finished product can change with regard to density,
viscosity, reflective properties and conductivity. For every
application VEGA has a solution that assures reliable
measurement data.
Products change but security stays
VEGA offers all current and emerging standards of signal
processing in its range of products. For continuous level
and pressure measurement, 4 … 20mA/HART 2-wire and
4-wire technology, Profibus PA or Foundation Fieldbus are
available. For point level detection and switching relay,
contactless, or transistor outputs as well as NAMUR signal
and current signal are available. VEGA’s measuring
instruments can always be adapted to equipment already
installed.

plics® – the idea with a future
plics® makes everything easier – from selecting to
ordering, right through to set-up, maintenance and
service. In this modular system, you combine the
performance features you need to solve the measuring
problem – both technically and commercially.
Whoever has once worked with plics® can apply the set-
up, wiring and adjustment concept to any other
application, and even to other measuring principles.
Because of the broad range of the technology and the
“easy choose – easy use” concept, plics® provides an
element of security and reliability for every application.
Easy is better
plics® offers optimum performance for disposal processes
due to reliable and precise measured value output. plics®
instruments possess the comprehensive certification
required for responsible handling of chemicals: Approval
according to FM, CSA, ATEX and more.
plics® good for human life and the environment
plics® offers unlimited selection and combination of
sensors, process connections, electronics modules and
housings. For the engineering department, this translates
into easy, straightforward planning and instrument
selection. The plant builder benefits from the short delivery
time, uncomplicated connection and quick set-up, while
the user profits from operational reliability, simplified
maintenance and reduced inventory costs.

PLICSCOM and PACTware
PLICSCOM, with its entirely new adjustment philosophy,
offers extensive practical convenience. It can be mounted
in the housing in four positions 90° apart. Indication and
adjustment are carried out via 4 keys and a concise dot-
matrix graphical display. The adjustment menu with
selectable language is clearly structured and allows easy
set-up. Afterwards, PLICSCOM serves as indicating
instrument: level and pressure values are viewed directly
through the screw-on lid with glass insert in the requested
unit and presentation style.
Set-up and indication with PLICSCOM
In the unlikely event of failure, the cause is displayed
on the PLICSCOM. In addition, instrument data such as
measuring range, process connection, seal material as
well as recorded process data of level, pressure and
temperature can be called up. In conjunction with suitable
instruments, the PLICSCOM also displays echo curves.
When the sensor is replaced, the PLICSCOM ensures
that the measuring loop is quickly up and running again:
all sensor data is saved by a quick keystroke and copied
afterwards into the replacement sensor.
Diagnosis and service with PLICSCOM

PACTware is a new industry standard configuration
software for field instruments, from the mobile computer
through to the control room. As a free-of-charge,
manufacturer-independent software, PACTware composes
the Fieldbus-independent interface for data exchange
between all current protocols of communication-capable
field devices, e.g. HART and Fieldbus. In practice this
means: all plics® instruments – from reactor to storage tank
– can be set up and operated via one single program with
a completely integrated user interface.
Configuration and parameter adjustment with
PACTware
Because of PACTware's capability of plant-wide failure
recognition and evaluation, it is an ideal decision platform
for maintenance measures. PACTware accesses and
makes available the data of all communication
components and field devices continuously and centrally.
Thus, after the status of field devices and other system
components is recognised and evaluated, appropriate
measures can be taken – e.g. pre-emptive servicing. This
increases the operational availability of the plant and
ensures a smooth production process.

VEGADIF 35
Garbage incineration
In addition to landfills, incineration is the most common
method of disposal of household waste. Modern
incineration plants are very complex systems consisting of
a waste bunker, a furnace, a boiler and a combustion gas
scrubber. A predefined quantity of refuse from the waste
bunker is placed on the combustion grate and transported
through the furnace. To ensure complete combustion of the
refuse, a temperature of up to 1000°C (1832°F) has to be
maintained. Large amounts of air are injected for this
purpose. Through sophisticated incineration technology
and flue gas purification, the emission of pollutants is
reduced to a minimum. State-of-the-art measurement
technology enables automatic and efficient operation.
Control and monitoring of the furnace are of key
importance. Air quantity and air pressure must be
precisely measured.
As hot as hell in there
The influx of primary and secondary air is carried out via
two large main ducts which split up into smaller individual
ducts. The primary air is blown through the combustion
grate from below, the secondary air from above. The air
flow in each respective main duct is measured in a section
containing a venturi tube. This is a defined constricted
area in the duct in which a pressure drop of a few mbar
takes place. With its metallic measuring cell and suitable
measuring range, VEGADIF 35 measures this pressure
drop precisely. Its output signal corresponds to the air flow.

11
VEGABAR 52 VEGABAR 64
To provide additional monitoring, the air pressure in both
main ducts (approx. 25 - 60 mbar / 0.362 - 0.87 psig) is
measured by a VEGABAR 52 pressure transmitter. The
furnace is constantly operated with a slight underpressure.
This facilitates the influx of air for combustion.
Pressure measurement of combustion air
with VEGABAR 52
The still hot cinders fall into the water-filled discharger at
the end of the combustion grate. To enable automatic
cinder discharge, a continuous level measurement of the
water/cinder mixture is necessary. This is carried out with
two VEGABAR 64 pressure transmitters. Their front flush
ceramic measuring cells are abrasion-resistant and
protect against build-up.

Landfill
Landfill leachate results from permeating surface water
and water pressed out during compaction of the waste
mass. It can contain harmful substances such as various
salts, ammonium and carbon compounds which are
flushed out in the process and represent a serious threat
to underground and surface water. For that reason, the
leachate is gathered via a ground seal into drainage pools
and wells and fed to a multistage treatment plant. Level
measurement in the well controls a drainage pump and
also gives the landfill operator important information on
the status of the landfill.
Leachate – something's brewing there
Well galleries are used to systematically gather leachate.
They are made of long steel tubes driven vertically
through the cross section of the dump. Water collects at
the bottom of the tube and is forwarded to the leachate
treatment plant via special submersible pumps. The level
in the individual tube is measured with a VEGAWELL 72
suspension pressure transmitter. With its PE coating, it has
optimum protection against the corrosive leachate. The
output signal controls the frequency converter of the
pumps. By means of this measurement, the special pumps
are protected from dry running, and the leachate level is
prevented from getting too high.

VEGAPULS 63
The free oils contained in the leachate are separated by
gravity into plastic settling tanks. After further chemical
treatment, the leachate arrives at a stripper column. This is
a slender, approximately 3 m (9.84 ft) high reactor into
which air is pumped from below and leachate from above.
Here, nitrogen compounds are converted and carbon
compounds degraded with the help of microorganisms.
This pre-treated leachate is finally cleaned and filtered in
additional physical stages and then separated as
distillate. To ensure the optimal operating conditions
inside the stripper column, an accurate level
measurement in the bottom area of the column is
necessary.
Leachate treatment
To facilitate the reaction, the middle zone of the column is
packed with carrier material. Due to the influx of air, the
surface of the liquid medium is very agitated. Direct level
measurement inside the column is impossible. For this
reason, level measurement is carried out in a bypass tube.
A VEGAPULS 63 radar sensor is used for this application.
Its highly resistant antenna system guarantees a precise
and reliable measurement.

VEGAPULS 62 VEGACAP 64
Treatment of special waste
Lacquers, paints and thinners, among other things, as well
as acids, alkalis and emulsions are treated as special waste.
Many of these are by-products from applications in the
chemical industry, in metal processing and in vehicle
construction. In special waste treatment, substances that
impact the environment are converted to be compatible with
the environment, i.e. capable of being disposed of in waste
repositories. Level measurement, e.g. in storage tanks and
receiving vessels, ensures automatic, monitored operation of
the facility and thereby protects human life and the
environment.
Special waste – a “cocktail” of chemicals
Lacquers, paints and thinners are stored in tanks up to 15 m
(45.7 ft) high. These substances require no pre-treatment
and are fed directly to incinerators via smaller day tanks.
Agitators inside the tanks prevent fibrous materials and co-
lour pigments from clumping and settling on the bottom. The
VEGAPULS 62 radar sensor is the ideal solution here for
level measurement. The radar measurement is unaffected
by the ambient conditions, such as strong vapour emission
of the waste, and delivers accurate measuring results even
when the agitators are in motion.

- non-contactmeasurement of allmedia
- very small minimumdistance to the product

Capacitive compact level switches, being completely
unaffected by buildup, have proven to be a good solution for
level detection of lacquers and paints. For that reason,
VEGACAP 64 is applied as dry run protection for the agitators
and discharge pumps.

The receiving vessels are sunk into the ground and are
composed of double-walled, plastic-coated steel tanks.
Because the delivered acids, alkalis and emulsions have
very different properties, the level measurement should be
made with non-contacting methods. VEGAPULS 63 radar
sensors work reliably under difficult measuring conditions,
such as steam, vapours, extreme temperature fluctuation and
surface agitation from agitators. Corrosive media, as well as
salt deposits caused by neutralisation, are no problem for the
buildup-free, flat antenna of top-grade TFM-PTFE plastic.

Maximum signal with VEGACAP 63
The maximum signal from the fully PTFE-insulated
capacitive level switch VEGACAP 63 stops the filling
process and prevents overfill.
Leakage detection with VEGASWING 63 and
VEGATOR 636 Ex
A leakage warning system is an absolute requirement for
double-walled vessels holding water-contanimated liquids.
The ECTFE-coated vibrating level switch VEGASWING 63 is
perfect for this application. In conjunction with the compatible
signal conditioning instrument VEGATOR 636 Ex, it fulfils the
requirements of SIL 2. The mandatory function test is carried
out simply by pressing a key on the signal conditioning
instrument.

Biogas production and composting
- easy installation- rugged and
maintenance-free
Organic waste is created by private households, industry and
food processing plants. Beside compost products, valuable
biogas fuel can be obtained from this waste. 80 to 100 m³ of
biogas can be generated from one metric ton of organic
waste – that corresponds to 55 to 100 l of heating oil. After
being delivered, the organic waste is shredded and
machine-sorted into substrate and structure components. The
substrate is then fed via a buffer tank into the multi-stage
fermentation process which, at 55°C (131°F), operates in a
“thermophilic” temperature zone. Fermentation sludge and
biogas are the end products of this process. The fermentation
sludge is mixed with the structure mass to create high-grade
compost products. The biogas generated in the reactors is
collected in gas storage tanks and later converted into heat
and electricity in a combined block heat and power plant.
Organic waste – raw material for biogas and compost
Backup detection with VEGACAP 66
The substrate is brought to the buffer tank via belt or screw
conveyors. A fully insulated VEGACAP 66 capacitive cable
probe detects irregularities and prevents backup or
overfilling of the buffer tank. Depending on the temperature,
steam may form in the buffer tank. Completely uninfluenced
by this, VEGACAP 66 continues to function reliably.

- reliable long-termstability
- small measuring rangefrom -0.05 ... +0.05 bar(-0.725 ... +0.725 psig)
To monitor gas generation in the reactors, gas pressure of
only a few mbar is measured continuously.
The VEGABAR 52 pressure transmitter is recommended
for this task. Its ceramic CERTEC® measuring cell provides
the small measuring ranges required for this precision
measurement.
Pressure measurement with VEGABAR 52
The mandatory overfill protection is realised with a
VEGACAP 64 capacitive rod measuring probe. It requires no
adjustment and is ready to operate immediately after
installation. Due to the fully insulated, buildup-insensitive
construction, it delivers an exact switching point even with
strongly adhering product.
Overfill protection with VEGACAP 64
Level measurement in the reactor with
VEGAPULS 66
To ensure efficient fermentation, the optimum levels of the
individual reactors must be ensured. The typical measuring
conditions in the reactors include layered gasses,
temperatures up to 55°C (131°F) and multistage agitators.
For this reason, VEGAPULS 66 radar sensors with large horn
antennas are implemented for continuous level
measurement. These instruments measure the level with
extreme precision, even under difficult process conditions.

Fuels from renewable raw materials
Through a new, patented method, wood chips can be
converted into fuel. This is carried out in a multistage process.
In the first stage of the gasifier, the wood chips – at
temperatures up to 500° C (932°F) and pressures up to 5 bar
(72.5 psig) – are decomposed into biomass cokes and tar-
laden gas. The biomass cokes are carried out on conveying
equipment and fed to the grinding process through a system
of locks. To allow this process to run continuously, automatic
discharge via lock hoppers is necessary. For this purpose,
the lock hoppers are equipped with sensors to measure
level, limit and pressure.
Put some wood in your tank!
Level measurement in the lock hoppers
with VEGAFLEX 61
The lock hopper is filled with biomass cokes. A guided
microwave VEGAFLEX 61 sensor in cable version
measures the level continuously. When the lock hopper is
full, the filling process is stopped and the valve is closed.
The special advantage of VEGAFLEX 61 is its reliable
measurement performance even under unfavourable
conditions, such as low DK (dielectric constant) value of
the biomass cokes, and strong dust generation during
filling.

- flush ceramic front- high abrasion
resistance- long-term drift less

When the lock valve closes, no cokes should be in the
chute – otherwise the valve would not close completely.
Backup detection is provided by a VEGAVIB 61 vibrating
level switch. Its patented rod design, in contrast to a tuning
fork, has been optimised for use in bulk solids. It avoids
material getting wedged in the instrument and provides
maximum functional reliability.
Backup detection with VEGAVIB 61
Before the cokes can be transferred to the grinding
process, the pressure of approx. 5 bar (72.5 psig) in the
lock hopper must be released. Vessel discharge can only
take place after pressure equalisation. For that reason, the
pressure is measured via VEGABAR 64. With its tube
extension, it sits perfectly flush with the vessel wall. The
robust ceramic diaphragm is highly resistant against
abrasion.

Recycling plastic windows
The recycling of plastic windows yields raw material for the
production of new high-quality windows. Whole plastic
windows including glass, mountings, sealing and
reinforcements are chopped into small pieces in the
shredder. Afterwards, the metal, glass and rubber are sorted
out with the help of special separators. The remaining chunks
of PVC are then reduced to a uniform particle size in a
cutting mill. This material is sorted according to colour and
then granulated. The end product of this recycling process is
a sorted, high-quality PVC granulate. It is stored in large
mixing silos. These are equipped with mixing tubes that
ensure thorough mixing of the grey-white PVC granulate. The
content of the silo is registered via level measurement. The
measurement data provides the basis for regulating
production and distribution.

Typical application conditions are noise and dust during the
filling process and abrasive products. That’s why the
VEGAPULS 68 radar sensor is the most suitable solution.
The instrument is non-contacting and wear-free and was
specifically developed for solids with unfavourable reflection
characteristics. Its sensitivity is many times greater than that
of conventional radar sensors. That ensures accurate
measuring results even when the granulate has a low
dielectric constant.

Recycling process water
The levels in the operating, rinsing, and filtrate vessels
are measured with the VEGAWELL 72 suspension
pressure transmitter. The unique advantages it offers for
this application are the front flush CERTEC® ceramic
measuring cell and easy mounting from above.
Level measurement in the receivers
Water from part cleaning and degreasing equipment is
often contaminated with oil. This leads to increased fresh
water consumption and shortened equipment service life.
With modern microfiltration technology, oil can be easily
separated from water. Via special pre-separation
equipment, the residual oil content of the oil/water mixture
is reduced to less than 0.5%. In the subsequent
microfiltration facility, it is pumped through tube-shaped
ceramic membranes at a pressure of approx. 5 bar
(72.5 psig). Here it is separated into so-called retentate
(concentrated oil/water mixture) and filtrate (purified
water). To enable automatic operation of the microfiltration
facility, level measurements in the receivers and pressure
measurements around the ceramic membranes are
necessary.

Ground water regulation
In brown coal strip mining, a continuous lowering of the
groundwater level is necessary in order to protect the
mining area from flooding and the pit walls from water
pressure. A large number of filter wells with underwater
motor pumps are kept in operation for this purpose. The
high-performance pumps are controlled by frequency
converters and operate non-stop. This prevents the pump
shaft from blocking due to the effects of iron and
manganese oxide deposits. To effectively lower the water
level, several hundred million cubic meters have to be
pumped out each year. Precise level measurement is
required in each of the up to 750 m (2460 ft) deep wells to
regulate pump output.
Lowering groundwater via filter wells
Lowering the pump and pressure pipe is very difficult and
expensive. For this reason, extremely high reliability is
required of all components. VEGAWELL 72 fulfils this
needs. The ceramic measuring cell is so robust that it is
mounted front flush without additional protection. The
water flowing around it gives rise to a “self-cleaning” effect
that prevents premature mineral deposits and thus
incorrect measurements.
