Our water

Water is the most important natural resource for both man and nature – and in seemingly abundant supply.
Seemingly. Of all the immeasurable water supplies that our earth holds, only a small part is directly usable inreality. Almost everywhere where water is to be used for drinking, it must first be cleaned, softened, desalinatedor sterilised.

If we look at the earth's surface, then we see that more than70 percent is water.
Most, however, is seawater. Salty and undrinkable. Of theentire volume of all water resources, around 97 percent is salt
water, and only about 3 percent is freshwater. The latter ismostly bound in glacial ice.
Against this background, it is understandable why suppliesof drinking water are perhaps mankind's greatest challenge:
Right now, around 1.2 billion of earth's inhabitants – morethan one in six – have no access to clean drinking water.

4

And by 2025, experts estimate there will be over three billion.
In more than 30 countries around the world persistent water
shortages prevail; it is expected that, by 2025, this will be a
problem for 50 countries.

Status, problems, opportunities

The thirst grows

Technology can help

The global situation is worsening as the thirst for drinking
water grows everywhere, and not only through the growth inworld population.

An important role for the better usage and development ofwater resources is played by modern technology for water
sourcing, treatment and distribution.

Here, a particularly large part is also played by agriculture,
which today, averaged around the world, requires about
70 percent of all water supplies, industry a further 20 percent,and private housing around 10 percent.

Here, highly advanced systems and processes are used,which only function with reliable measurement and control
technology.

According to a forecast by the United Nations Environment
Programme (UNEP), by 2025 the water demand from agriculture will have grown by 20 percent, in industry by 50 percent
and in households by 80 percent.

As such, WIKA products and solutions contribute the world
over so that water is treated carefully and sustainably as avaluable commodity.

Water, and that is the positive message, is used, but it isn't
used up. The amount remains the same – only a negligible
part evaporates into space.
However, the technical expenditure in using, processing and/or recycling water resources is immensely high.
Worldwide, around 500 billion euros are spent on thisannually, with the trend growing continuously.

5Drinking water

Drinking water is the most elementary foodstuff – its supply therefore has the highest priority.
For this reason, clean drinking water has been a UN human right since 2010.
The high demands on quality and availability through strict laws, precise guidelines and corresponding structuresare, generally, so perfectly fulfilled, that drinking water, for most people in the Western world, is taken for granted.
The high investment that goes into an uninterrupted water supply is not even recognised by most consumers.

Drinking water is obtained from the widest variety ofsources: groundwater, rain water, surface water (particularly
from rivers and lakes), and increasingly also from the sea.
Depending on its origin, it must be conditioned for humanconsumption, or for other uses, with a greater or lesser
technological investment. This includes processes suchas filtration, desalination, de-acidification, degassing,disinfection and the removal of unwanted substances suchas iron and manganese.

6

For the public water supply in Germany, the DIN 2000 and2001 standards are precisely defined.
In these, amongst other items, the requirements for drinking
water as well as for the design, building and operation of
supply plants are specified exactly.

Drinking water

From deep down
In many countries, especially in Europe, the primarysource of drinking water is from groundwater. In
Germany this accounts for approximately 70 percentof the water supply. The water extracted from various
depths – quite often several hundred metres under theearth's surface – as a rule is hygienically perfect.

WIKA submersible pressure transmitters from stainlesssteel have been applied for many years in drinking watersupply. The measuring instruments can be easily installed
and operated completely submerged in water. They deliver
reliable measuring signals throughout the years.

Powerful submersible pumps transport the groundwater
to the surface. The ratio between the water extraction andthe replenishment of groundwater must be consistently
and carefully controlled. This is achieved through levelprobes, also known as submersible pressure transmitters,
which permanently measure the water level. They must be
particularly low-maintenance and long-lasting.

7

From the sea
Many populated centres with drinking water shortages
are located right near the sea.
The treatment of strongly saline seawater for usage tothe quality of drinking water is a proven process.
Through continuous development and optimisation, theproduction costs have been reduced dramatically andthus the desalination of seawater can be realised costeffectively.
Desalination thus contributes globally to the securingof drinking water supplies which are able to satisfy thecontinuously rising demands of conurbations.
Two treatment methods, in particular, have become established: reverse osmosis and distillation processes.

8Drinking water Reverse osmosis
is a filtration process, in which the seawater is forced througha diaphragm. In the process, the pollutants are retainedby the diaphragm, while the cleaned water is collected forfurther use.
Since, during osmosis, the molecules flow from an area withlower concentration to an area with higher concentration,
so here we are speaking of a process that is the inverse of
osmosis.

 Distillation process or “MSP”(multi-stage flash evaporation)
is a thermal process in which the seawater is passed throughpipes via heat recovery zones and into the end heater. Here,the seawater is heated to over 100 °C and flows back into thefirst chamber of the heat recovery zone.
Thus part of the seawater is evaporated due to a lower
pressure, condenses on the pipes above and is collected as
freshwater.
The remaining seawater flows into further chambers, where
the pressure is reduced in stages, and thus further freshwater
is produced.

9

To the consumer
In most regions, drinking water is distributed to theconsumer through supply networks.
The components in these systems are water pipes,
pressure regulation and measurement and monitoring
devices. In most countries there are specific legal provisions that regulate the handling of drinking water.
Examples:Thus, in the German Drinking Water Ordinance, theessence is described in § 1: “The purpose of the regulation is to protect human health from the adverse effects
resulting from the contamination of water intended forhuman use, by ensuring its purity and fitness for consumption […]”.

The water supply is ensured either by public or privateorganisations. Apart from a consistent water quality, theymust, in particular, provide an adequate pressure within the
supply network.
Depending on the topography in the particular supply area,
the pressure must occasionally be decreased, and frequently
increased. In both cases, mainly Bourdon tube gauges areused to monitor the pressure.

10

An important task in conjunction with this is also ensuring
a constant pressure via compensatory measures during
times of peak usage and also during particularly low water
consumption.
For this purpose pressure transmitters (or pressure gauges
with electrical output signals) are used, not directly on thepumps, but rather mounted at distributed points in the supply
network, for example at valves.
Through the signal from the pressure measuring instrument,
the speed of the appropriate water pump can be regulated
such that the supply rate matches the requirements exactly.

Drinking water

Hydrostatic level measurement
Level sensors based on hydrostatic pressure measurement generally measure the level or filling height in a
vessel in accordance with the following principle:
A liquid generates, through its density and the force ofgravity, a weight force which increases with the filling height.
This weight force, increasing proportionally with the fillingheight, is called the liquid column, and is not dependent on,
for example, foam, turbulence or vessel fittings.
Hydrostatic pressure sensors are gaining in popularity
within continuous level measurement through their simple
application and quick commissioning.

So if one selects a hydrostatic pressure sensor, e.g. a
WIKA model LH-20 submersible pressure transmitter/levelprobe, this measures the height-dependent weight force,
acting from a liquid column, as a hydrostatic pressure. Fromthe measured hydrostatic pressure and the density of the
product, one can now calculate the filling height of the vessel.
Hydrostatic level measurement has enjoyed strong popularity
for many years and represents by far the most frequent formof electrical level measurement. Above all, it is notable for its
high reliability and its very low installation cost. Hydrostaticlevel measurement is therefore seen as particularly simple
and robust by those that use it.

11Process water

The quality requirements for water used in industry depends, primarily, on its application within the production
process (e.g. cooling, boiler feed or production water).
To ensure the required water quality, depending on the quality of the raw water, a greater or lesser intensityof water treatment must be performed (filtration, softening, desalination, etc.). Ultrapure water, as in the foodindustry, thus increasingly becomes the standard.

Strict legal requirements and cost pressure are forcing
companies to adopt ever-more complex water management.
The application and consumption of the resource is
optimised in a variety of ways, and the wastewater volume isthus minimised. Keyword “process-integrated environmental
protection”:
Here, for example, wastewater is conditioned via various
techniques (diaphragm, flotation, anaerobic processes)
into renewed process water. And efficiency is also of prime
importance with other commercial uses beyond industry,
such as irrigation in agriculture.

12

Process water

 SIP and CIP cleaning
Sterilisation-in-place (SIP) and cleaning-in-place (CIP) are
fully automated processes for sterilisation in pharmaceuticaland biotechnology plants. Here, the typical cycle temperatures normally operate in the range of 120 ... 134 °C.
These cycles are slowly cooled with pressurised water. With
these processes, no components need to be taken apart forcleaning.
The individual plant segments are rinsed through in different
stages with cleaning fluid, and between these with cleanwater. In tanks, built-in spray heads carry out these tasks.
In order to obtain an optimal result, the pressure of thecleaning jet and the rinser jet must be set exactly to thegeometry of the vessel and the spray head, as well as setting
it for the degree of pollution. For this, a water pressure of
between 1 and 6 bar is needed.
All measuring instruments needed for these cleaning processes must fulfil the requirements of the pharmaceuticaland food industries. Therefore, the pressure transmitters andmechanical measuring instruments must be installed withhygienic process connections.

 Filtration of process water
Process water for cooling circuits, steam generation andchemical industry solutions should only contain a small
number of electrolytes. Too high water hardness can lead to
calcification while an excess of oxygen and carbon dioxide
can lead to corrosion in the plant. Process water must be
conditioned differently for each application, e.g. with different
filtration processes. The permeate stream can be controlled
by comparing the water pressure before and after the filters.
For these environments pressure transmitters, above all,must be flush and free from dead space. The pressure
differential determined by them can then be evaluated for thefilter monitoring.

13 Industrial water
For industrial water, a cleaning standard is often needed,which is almost equally as high as for the product pipelines
themselves. Also with this there must be no chance of germ
growth.
Therefore, for pressure control, one should use pressuretransmitters with flush diaphragms or mechanical measuring
instruments with diaphragm seals fitted (dead space free).
The wetted parts of the diaphragm seals can be manufactured from corrosion-resistant materials – e.g. Hastelloy –when, for cleaning, solutions with much salt or chlorine areused.

 Ultrapure water production
Ultrapure water is required for highly sensitive processes, forexample, in medical engineering, the pharmaceutical and thefood industry, and also in semiconductor production. Its production requires a commensurate input. Each step to remove
impurities from the water requires differentiated pressure andtemperature monitoring. The most frequently used, reverse
osmosis, is followed, for example, by ion exchange, active
carbon filtration, ultrafiltration and sanitisation, whereby all
microorganisms are safely killed at temperatures of morethan 80 °C.

14

Process water Pharmaceutical water
The pharmaceutical industry has particularly high standards
for treated water.
It must meet high quality requirements since it is used as abase material in pharmaceuticals. A correspondingly higheffort is thus required in the manufacture and control of thisraw material.
With the manufacture of purified water (PW) and highly
purified water (HPW) in accordance with the European
Pharmacopoeia, drinking water is prescribed as thestarting material corresponding to the current drinking
water regulations. A specific challenge is represented by
the manufacture of water for injection (WFI), thus water for
medicines for parenteral application, since these materials
are injected directly into the body.
Raw water qualities as a starting material vary greatly andfluctuate considerably. This has the consequence that theplants must be adjusted to the local conditions in order thatconsistently high quality can be produced. The required
quality and process parameters must be permanently
monitored through specific measurement technology andanalytics.

15

Wastewater

The treatment of wastewater from private households and industry, and from precipitation contaminated with
pollutants, without doubt, rates as one of the most important responsibilities of the public utilities.

Modern wastewater treatment plants clean the wastewater
mechanically and biologically in three phases, before returning it to the receiving water (streams and rivers).
The increasing contamination of the water caused bypharmaceutical matter will make a fourth stage indispensable
in the foreseeable future.
The European Union, for example, is enforcing wastewatercleaning with the goal that all watercourses within its borders
will be brought up to an ecologically perfect condition.

16

Continuously increasing requirements due to ever morerecent constraints and laws, and with that the demandson the technical equipment: automation for more safety,
the highest possible equipment availability, increasing theefficiency through process procedures and energy usage.

Wastewater Rain overflow basins
Rain overflow basins protect the sewage system against
heavy precipitation.
They store the excess precipitated water until drier weather,when it can be gradually pumped into the sewage system.
For smooth pumping, the level in the basins must be monitored continually. Submersible pressure transmitters ensure
reliable level control.
Their measuring signals support the regulation of the waterlevels and guard against both the dry-running of the pumps
and the tanks overflowing. Major damage to the pumping
plant or the immediate environs of the basins is therefore
prevented.
The design of submersible pressure transmitters ensuresa high longitudinal and transverse water resistance for thecable and cable entry and thus a long service life: Even whensubmerged for many years, no water will enter the probe.

 Wastewater pumping stations
Pumps control the heartbeat of numerous processes in thewastewater system. Important switching points at the edges
are the wastewater pumping stations or lift pumps − in Berlin,for example, 150 such stations are operated. They lift thecollected wastewater to a level where it can flow naturally
down, or through pressured pipes, to the sewage treatment
plant. In addition to exact level measurement by submersiblepressure transmitters, permanent temperature measurement
protects the pumps against failure due to dry running. For
this task resistance thermometers specifically designed
to measure bearing temperatures are used. Integrated
transmitters increase the safe and reliable transmission of
the measuring signal to the control room.

Versatile
With electronic process transmitters, the measured value canbe read on site as well as being transmitted to a process control
system, a controller or a terminal.
The data transfer is achieved using an analogue 4 ... 20 mA
signal or via a bus protocol. With the HART®, PROFIBUS® PA or
FOUNDATION™ Fieldbus bus systems, there is the possibility totransmit further information from the process and/or measuring
instrument, in addition to the primary current signals, such as theoperating hours or the sensor temperature.

Large number of instrument variants
With the different diaphragm materials or coatings, the mostsuitable version for each operating environment can be selected.
In some cases, for particularly aggressive media or high processtemperatures, special materials such as tantalum, Hastelloy or
specific surface coatings are the most suitable solution.

Mechatronic measuring instruments
Wherever the process pressure has to be indicated locally and,at the same time, a signal transmission to the central control orremote centre is desired, the intelliGAUGE® instruments can beused.

Our offer is completed by the mechatronic pressure gauges withswitch contacts, making it possible to simultaneously monitor theequipment and to switch circuits.

Through the combination of a mechanical measuring system andelectronic signal processing, the process pressure can be readsecurely, even if the voltage supply is lost.

Limit indicator
The limit indicator, which is available as an option, finds its application wherever overpressures must be displayed with certainty andnot be tampered with. The limit indicator is a mechanical display
fitted on the dial, with two settings: If the indicator is in the green
area, the pressure limit being monitored has not been exceeded.
If the indicator is found in the red area, the set pressure range has
been exceeded at least once. In this case, the indicator will remain
permanently locked and protected from tampering in the red area.

to 0 ... 1,000 bar and static overlay pressures up to 400 bar are
possible.

These differential pressure gauges are used to monitor
the pollution degree in filter systems
the level in closed tanks
the overpressure in clean rooms
the flow of gaseous and liquid media
and they control pumping plants

Mechanical pressure switches
Mechanical pressure switches open or close a circuit, dependingon whether the pressure is rising or dropping.
Due to the use of high-quality micro switches, the mechanicalpressure switches are notable for their high precision and longterm stability. Furthermore the direct switching of electrical loads
up to AC 250 V / 20 A is enabled, while simultaneously ensuring ahigh switch point reproducibility.

Many mechanical pressure switches come with a SIL certificate
and are thus particularly suited for safety-critical applications. In
addition, with their 'intrinsically safe‘ and 'flameproof enclosure‘
types of protection the pressure switches are ideally suited forpermanent use in hazardous environments.

Diaphragm pressure gauges
Diaphragm pressure gauges for high overpressure safety
The application areas for these gauges with diaphragm pressure
element are gaseous and liquid aggressive media. Instrumentswith open connecting flanges are even suitable for highly viscousand contaminated media, also in aggressive ambience.
Typical scale ranges are from 0 ... 16 mbar to 0 ... 40 bar. Dependant upon the pressure range and the instrument model, overpressure safety of 3 x or 5 x full scale value is possible as standard.

For special designs, an overpressure safety of 10, 40, 100 or 400
bar is possible, with the measurement accuracy maintained. Liquid
filling the case ensures a precise instrument display, even withhigh dynamic pressure loads and vibrations. Special wetted-parts
materials are available as options.

Bourdon tube pressure gauges for general applications
These pressure gauges are suitable for liquid and gaseous media,
so long as they are not highly viscous or crystallising and do notattack copper alloy parts. The scale ranges cover pressures from
0.6 ... 1,000 bar.

These instruments are manufactured to EN 837-1 (Bourdon tube
pressure gauges; dimensions, metrology, requirements and testing). For measuring points with high dynamic loads, such as fastload cycles or vibrations, a liquid-filled design should be used.

Connection to the process withdiaphragm seals
Diaphragm seals

Advantages of diaphragm seals

Diaphragm seals separate the pressure gauge, pressure transmitteror pressure switch from the measuring medium and ensure a process connection which is either free of dead spaces or where deadspaces are reduced to a minimum.
The isolation is achieved by means of a flexible metal diaphragm.
The internal space between the diaphragm and the pressure measuring instrument is completely filled with a system fill fluid. The
process pressure is transmitted by the elastic diaphragm into thefluid and from there to the measuring instrument.

In contrast to ceramic principles, with diaphragm seals - as aresult of the measuring cell's metallic construction - additional
sealing elements are eliminated, and so the maintenance burden
is significantly reduced. Ceramic measuring cells exhibit a highsensitivity to dynamic loads. With any sudden pressure spikes, theceramic cell can be destroyed. In these cases, combinations ofpressure measuring instruments and diaphragm seals are clearly
preferable.

Electrical temperature measurement
Design of an electrical thermometer
An electrical thermometer, as a rule, is modular in design and consists of 3 main components: the thermowell, the connection
head and the measuring insert.
The thermowell is used for adapting the thermometer to theprocess and to protect the sensor against the sometimes harshprocess conditions.
In the connection head, the electrical connection of the measuring
insert is made, which can either be fitted with a ceramic cap or atemperature transmitter.

With a rotatable screw connection between the thermowell andthe connection head, this can be rotated in the desired direction,and in addition, if required, the connection head can be removed
together with the measuring insert.
This allows the thermometer, with the entire measuring chain,
to be calibrated directly on site without having to disconnect theelectrical connections. This avoids having to open the process,and thus a potential risk of contamination is minimised.

Resistance thermometers
Resistance thermometers are particularly suited, as a result of
their quality and measurement accuracy, to applications in the foodand beverage industry and also the pharmaceutical, biotechnology
and cosmetics manufacturing industries.

Resistance thermometers are equipped with metallic-conductor
based sensor elements which change their electrical resistanceas a function of temperature. The connection to the evaluationelectronics (transmitter, controller, display, chart recorder, etc.)
can be made with a 2-, 3- or 4-wire circuit, depending on theapplication.

Digital indicators, temperature
controllers
With digital indicators, the measured values from electricaltemperature sensors or from pressure and temperaturetransmitters are shown on a display. Integrated alarm outputs
enable, in addition, the control of the measured process values.
Even simple two-position control, such as level control, is possible
with the switching outputs from the digital indicators.

Temperature controllers are used to control the temperature in
production processes or for the temperature regulation of raw
materials and finished products in storage and transport vessels.
With the help of switchable set points, different set points can beeasily selected. Via optional serial interfaces, controllers can beconnected to a network and connected to a higher-level control
room.

Temperature measurement

Temperaturetransmitters
Transmitters convert the temperature-dependent change inresistance of resistance thermometers or the temperaturedependent voltage change in a thermocouple into a proportional
standard signal. The most commonly used standard signal is theanalogue 4 ... 20 mA signal, though digital signals (fieldbus) are
gaining more and more importance.
By using intelligent circuit concepts with analogue 4 … 20
mA signals, any sensor errors that occur are signalled andsimultaneously transmitted with the measured value over a twowire line (current loop).

The conversion and transmission of the standard signals(analogue or digital) is made over long distances and completely
fail-safe.
A temperature transmitter can either be mounted directly at themeasuring point in the connection head or on a DIN rail in acabinet.

The mechanical temperature measuring instruments work on thebimetal, expansion or gas actuation principle and cover scale
ranges from -200 … +700 °C. All thermometers are suited for
operation in a thermowell if necessary.
As a result of the integration of switch contacts and output signals
into our mechanical temperature measuring instruments, we canoffer a wide variety of combined instruments.

Thermowells
For connecting the thermometer to a process line or a vessel,
WIKA offers a comprehensive programme of thermowells.
Here, the following thermowell groups can be distinguished: Thermowells with flange connections, such as clamp or milk
thread fitting to DIN 11851, are integrated into the process via
an existing connection welded into the pipe or tank. For aseptic
processes, it is recommended that the connection is made via
VARIVENT® or NEUMO BioControl® flanges.

 For a direct connection of the thermowell into the pipeline,

thermowells are available which are fitted via an orbital weld or
via a hygienic process connection sandwiched into the pipeline(patent applied for, patent no. GM 000984349).
 For temperature measurement in tanks and larger vessels, thethermowells can be welded to the tanks with welding balls or
welding collars. One should however take care that the inner
welding seam is polished and passivated after welding.

Magnetic float switches
For vertical installation
A float with a permanent magnet moves reliably along with theliquid level on a guide tube. Within the guide tube is fitted a reed
contact (inert gas contact), which is energised, through thenon-magnetic walls of the float and guide tube, by the approach of
the float magnet.

By using a magnet and reed contact the switching operation is noncontact, free from wear and needs no power supply. The contacts
are potential-free. Magnetic float switches are also available withmultiple switch points. The switch functions always refer to arising liquid level: normally open, normally closed or change-overcontact.

For horizontal installation
Through the use of a float for a max. of 2 switch points a bistableswitch behaviour can be achieved, meaning that the switchingstatus also remains available, when the filling level continues
to rise above or drop below the switch point. The float switch issimple to mount and maintenance-free, so the costs of mounting,commissioning and operation are low.
