3Endress+Hauser - What is in the news?

Dear Customers and Colleagues,This edition of wazzup is a significant milestone for Endress+Hauser, and for me personally. In December 2012 I celebrated the completion of five years with Endress+Hauser. It is a significant event in our company and I was presented with my Five Year Pin by our CEO, Mr Klaus Endress, at a dinner in Germany. At the same time it gave me a chance to reflect on this time and how quickly it has gone.

Endress+Hauser South Africa also takes pride in the celebration of tenure and loyalty. As much as staff may come and go, as tends to be the norm in our fast changing market in South Africa, we have a core of long service colleagues who create the foundation around which our team continues to grow and learn. At the time of writing this letter, 57% of our staff compliment has more than five years of service, which is even more impressive if we count that the company heads have grown by 12% in this last five year period. Fifteen people were presented with new long service pins in 2012, including two staff members who achieved an unbelievable 20 years of service! It is this core of instrumentation expertise and application of knowledge that has enabled us, through our close contact with our customers and constant product development, to grow our sales by more than 80% in this same five year period.

For the Endress+Hauser group, February 2013 saw the celebration of 60 years since the day George Endress and Ludwig Hauser opened their doors in 1953. Of course the company is almost unrecognizable today from those humble beginnings, but we are proud to have maintained our family culture and values, which you can read more about in this magazine.

As you have already seen, this change is also reflected in our new corporate image and new wazzup magazine layout. If you have had a chance to visit our new head office in Sandton you will again see this change in the open, simpler and yet more customer orientated structure. If you have not visited us recently I hope you will soon get a chance, we look forward to welcoming you.

Finally, my thank you to our customers for your custom and support in 2012. Without this partnership we cannot learn and grow and I hope we will have a chance to continue this partnership in 2013.

With regards

4 Endress + Hauser - What is in the news?

Klaus Endress (64) has in recent years repeatedly announced his plans to withdraw from operative business. It was also known that, for reasons of age, no other member of the shareholder family would follow him right now. “We want to avoid speculations and discussions,” explained Klaus Riemenschneider, President of the Supervisory Board. “Announcing the succession at an early stage will provide clarity and smooth the transition.”

The new CEO will be Matthias Altendorf, currently Managing Director of Endress+Hauser’s largest production facilities in Germany. Since 2009 he has also been a member of the Group’s Executive Board. 45-year-old Altendorf has spent his entire working life at Endress+Hauser, beginning with a mechanic’s apprenticeship at the Maulburg factory, followed by advanced

Changes are on the horizon at the top of the Endress+Hauser Group. With effect from 1 January 2014, Matthias Altendorf will be the new CEO of the family-owned company. Klaus Endress, who has led the Group since 1995, will at the same time take his seat at the Supervisory Board.

training and further education. Working for Endress+Hauser Flowtec in Reinach, Switzerland, Altendorf took on more and more responsibilities in various positions until moving up into management as Marketing Director in 2000. In 2005, Altendorf finally returned to Maulburg as Managing Director.

The Supervisory Board’s spokesperson, Klaus Riemenschneider stressed, that this decision “in close consultation with the shareholder family and with their full support”. Klaus Endress underlined the importance of the time frame: “Mr Altendorf can hopefully be a good CEO of the Endress+Hauser Group for a long time – and if possible build a bridge to a younger member of the family as his successor.”

Klaus Endress described Mr Altendorf as an “Endress+Hauser

man through and through, reflecting the culture, values and convictions that characterize our company”, guaranteeing that the transition will be successful. Klaus Endress himself wants to ensure continuity by transferring to the Supervisory Board to replace retiring President Klaus Riemenschneider .

Andreas Mayr new Managing Director in Maulburg, Germany A successor to Matthias Altendorf has already been found. Effective from 1 January 2014, Dr Andreas Mayr will be the new Managing Director of the competence center for level and pressure measurement engineering in Maulburg, Germany. 51-year-old Mayr holds a PhD in physics. He has worked for Endress+Hauser in Maulburg since 1998. As Director of Technology, he has been a member of the management team since 2010.

Endress+Hauser Celebrates its 60th Anniversary!

It’s been 60 years and, Endress+Hauser is still family owned with a global network of companies, worldwide state-of-the art production facilities, a full product basket of quality products and still continues to expand. This success can be contributed to one of the company founder’s; the late Dr George Endress’ motto to satisfy customers’ needs and requirements, ‘First serve, then earn’, which is still valid today!

1953 to todayIt all began rather small and inconspicuously on 1 February 1953. Swiss engineer George H Endress and German banker Ludwig Hauser set up their company in a backyard in Lörrach, Germany. The first level measurement instrument was patented just two years later and these innovative measurement instruments soon enjoyed a good reputation in the industry.

World leader, measurement and automation specialist, Endress+Hauser is celebrating its 60 year milestone

headcount reached 4 000.

At the dawn of the digital transmission and communication era, around 1990, Endress+Hauser was actively involved in various fieldbus initiatives. In early 1995, the company founder handed over the business leadership to his second eldest son Klaus Endress who still runs it to this day.

Responding to the challenges of globalisation, Klaus Endress developed the international network of production and sales, while at the same time steadily expanding the company’s offering.

From device to solutionThe Endress+Hauser Group has evolved from being a vendor of devices and instruments to offering a complete basket of products, services and solutions to support our customers in operating their plants reliably, efficiently, cost effectively and environmentally compatible throughout their entire life cycle. “Our strength is that we are entirely driven by the market,” says Group CEO Klaus Endress. “We learn from our customers and strive to create sustained and outstanding benefits and value for them.”

Thanks to the global roots in different regions (more than 40 sales centres, 70 representatives and productions facilities in 12 countries including South Africa) and operating in various industries, the Endress+Hauser Group is well versed to cope with cyclical fluctuations. The lean and highly networked organisation guarantees flexibility and rapid response.

Company founder Dr. Georg H. Endress (centre) with workers in Lörrach, Germany, 1955.

“We trust in our strength and look ahead with confidence, but we must stay alert.”In the subsequent decades, the fields of operation were expanded to include flow, pressure, analysis and temperature, with new production sites built or bought for development. With a growing number of sales partners, Endress+Hauser gradually conquered first the European market and then the African, Asian and American markets followed. After Ludwig Hauser’s death in 1975, the Endress family became sole shareholders. At that time, the company had approximately 1 000 employees. Fifteen years later, the

Continuity is held high in the family-owned business: in spite of the finance and public debt crisis in 2009, no employees were laid off – with the result that a new sales record was promptly accomplished in the following year after the economy had begun to recover.

OutlookWith sales totalling one-and-a-half billion Euros, the Endress+Hauser Group achieved another record year in 2011 – in spite of a strong Swiss Franc and a flagging economy in Europe.

“Although the market is extremely volatile today, this year will be an excellent one for us,” says CEO Klaus Endress. “We trust in our strength and look ahead with confidence, but we must stay alert.”

With well-targeted acquisitions in biotechnology, gas analysis and energy management, Endress+Hauser has recently rounded off its product portfolio. With an equity ratio of more than 70%, the company is largely independent of lenders and is well equipped to meet the challenges of the future.

Next Level Instrumentation

Being the world market leader in level instrumentation, Endress+Hauser has many years of experience at its disposal – from planning and commissioning through to maintenance and plant management. The new instrument generation of the time-of-flight method offers outstanding properties in the radar instruments of the Micropilot family, just as the guided radar instruments of the Levelflex family launched in 2010 do.

Safe – Precise – Efficient

After its successful launch, more than 20 years ago, the development of Micropilot has continued in co-operation with our customers and users. Far more than 300 000 installed radar instruments and more than one million installed instruments according to the time-of-flight method underline our competence.The new Micropilot FMR5x family offers everything to guarantee safe and precise measurements in the chemical, oil and gas, life science, food and primary industries, from the standard product for basic applications through to high performance versions to be used in sophisticated applications like high-pressure or high-temperature tasks.

The hardware and software of the new instrument generation for the time-of-flight method were developed according to IEC 61508 and can be used in homogeneous redundancy up to SIL3. For example, Micropilot always checks its unobjectionable functionality within the instrument by continuous self-monitoring. If an error occurs, the instrument changes to the safety-oriented output. The recurring check (proof test) can be easily started by an optionally connected engineering tool or directly from the control room in which the connection between the instrument and the engineering tool is constantly monitored.

In its new instrument generation, Endress+Hauser has developed an even more intelligent and reliable signal analysis, using the echo signal curve – Multi-Echo Tracking. All of the echo signals are marked and tracked, not only the level signal. Thanks to the new analysis, the level signal is also acquired if it is partly covered by baffles like heating coils or agitators in the tank. This guarantees safe and precise measurements at any time.Another advantage of the new radar instrument is the HistoROM data management concept. Apart from the continuous backup of all relevant data, it enables customers to exchange defective main electronics in a fast and easy

10 Evan’s Energy Update

Evan’s Energy UpdateAre your Profits Vanishing into Thin Air?

I have often been asked to put into financial terms the cost of compressed air losses. Of course, as a first step, you must have some form of measurement system to get history from, in order to validate and quantify any losses. I have discussed this in previous columns, but for purposes of this column, I will focus purely on the losses that can be expected.

Some facts around compressed air:• Accounts for 10% of global electricity consumption.• As much as 95% is lost as unproductive waste

(mechanical losses, heat losses, wastage, misuse, leakage, etc.).

• Around 30% of compressed air disappears due to waste.• Compressed air losses are grossly underestimated in

most plants.

Now let us consider the costs of these losses. According to Guide Book Three, Compressed Air Systems, www.3e.uct.ac.za, a 3mm hole in a compressed air line equates to about 3.5kW in continuous power loss for that compressor supplying the line. This does not sound like a lot, but consider a typical plant situation where there may be say 50 leaks. Now the cost is R39 200 per month, R470 400 per year. Can you afford

to ignore or not measure this? The reality of the situation is that this is one of the easiest areas to reduce energy consumption in a process, simply by having a leak audit done and most importantly fixing the leaks.

The next question is: How do you ensure sustainability? By installing a comprehensive monitoring system in the process, and profiling the process prior to fixing the leaks, you can quantify the value of the leak repair initiative and set a new profile to work against in future. With limits set into the system, you can then allow the system to highlight when the process is returning to the “old” situation as the real time measures move out of the new profile. Using the system correctly you can then set your regular leak repair programme according to real data and not just a schedule. This is optimized maintenance. The system will also flag failures and errors in the system (large leaks, etc.) quickly for rapid response, saving the energy that would be lost without a real time system monitoring the process.

Now again ask yourself the question, can you afford to ignore this and not to have a monitoring system in place? I think the answer is clear. Endress+Hauser have been working in the energy efficiency arena for many years and are fully competent in developing a strategy and system that suits your process and requirements. We welcome you to contact us to discuss this further.

Enquiries: Evan Dent: Strategic Business Manager evan.dent@za.endress.com

Can we put this into financial terms? Definitely!• 3mm hole = 3.5kW power loss.• Let us say the compressor usage is a conservative 20

hours a day, 20 days per month. This is 400 hours per month.

• Let us use the old Eskom tariff of 56c/kWh• The loss is thus R784 per leak, per month (simply

3.5kW X 20 hrs X 20 days X 0.56c/kWh)

11One piece of advice

Operational Excellence in Calibration - Helping to Minimize your Risk

The importance of a reliable calibration partner?While calibration certainly plays a role in saving raw material and passing quality audits, it also guarantees your “recipe” is adhered to and above all promises your end-users a consistent level of product quality.

ISO 17025 three main driversCalibration is globally supported by standards such as ISO 17025 and consists of three main drivers:• Quality Management System

(QMS) (process).• Validation and traceability

(methods).• Competency (employees).The first driver, Quality Management System is well-known and you can easily check if your partner qualifies, especially if they are already certified or accredited.

The second point, the methods used, is also easy to verify as your partner is either able to demonstrate traceability and usage of validated methods or not - this is a black or white situation. Standard Operating Procedure (SOP) availability is an example of this. However, when it comes to the third point, employee competence it gets a little trickier. Even if handling competence seems simple to check at first, in reality competence is not

as easy to establish as the two first drivers!Training, accreditation and reproducibility to reduce your risksMost companies would say: “Of course our team is trained!” However, is a training course really sufficient to certify the Service Technician as competent to operate and maintain your process? Are your risks controlled?At Endress+Hauser, Service Training and proficiency tests are conducted worldwide with participants from various countries. The objective is not only to train service people to perform calibration using proven methodologies but also to ensure that when they are back in their respective countries, the methodologies used are relevant and efficient.For example, the qualification of a Service Technician for flow calibration consists of different modules:• Metrology. • Flow calibration. • Flow products.

Enquiries: Glenn SmithAdded Value Services Development Managerglenn.smith@za.endress.com

Each of these modules has to be validated independently, covering both theoretical and practical aspects, in order for each participant to obtain the qualification in each specific module. This guarantees our customers the value of the training provided. On top of this, for specific types of calibration, our technician’s ability is backed up after the certified training by proficiency testing, compliant with ISO13528. Internal certification is given based on successful assessment during training and allows us to assign competent technicians to calibration jobs around the world.This global initiative ensures that your Endress+Hauser calibration is performed:• In compliance with worldwide

standards. • With a high level of competence.

Next Level InstrumentationThe new standard in Radar - the Micropilot familySafe • Precise • EfficientMulti-Echo Tracking

Apart from instrument properties, the analysis of echo signals provides safety and reliability in Time-of-Flight level measurement.

In its new instrument generation, Endress+Hauser has developed an even more intelligent and reliable echo signal

evaluation by the echo signal curve – Multi-Echo Tracking.If obstacles, e.g. heating coils, protrude into the signal path in a measurement, they generate a corresponding signal. These interfering signals are suppressed, so that they are not analyzed. The problem of the traditional evaluation is that level signals below the suppression cannot be analyzed thus causing signal losses.

Innovative Multi-Echo Tracking offers the solution. All of the echo signals are marked and traced, not only the level signal. Thanks to the new evaluation, the level signal is also acquired if it is below the suppression – this guarantees safe and precise measurement at any time, e.g. also if the tank contains sources of interference.

HistoROM data management conceptThe innovative and intelligent HistoROM data management concept generates significant benefits in different areas of the life cycle.

HistoROM stores the parameters of an instrument during commissioning. If similar measuring points are commissioned, the display serves as a data carrier like a USB stick.

After commissioning of the instrument, the final parameter settings can be transferred from HistoROM to the display memory. In this way, the display serves as a HistoROM backup.If parameters are accidentally or intentionally set at the display during operation, this data is automatically changed in HistoROM. If, subsequently, the original status is to be recovered, the settings stored in the display may be transferred to HistoROM via the “Restore“ function.

16 Sollutions @ wazzup

In my previous piece, entitled ‘How it all fits together’, I made mention of Digital Fieldbus Technology and its “unusual” maintenance strategy requirements in basic terms. In this edition of wazzup, I elaborate further on the maintenance of Fieldbus Systems, paying particular attention to Profibus.

Profibus has a reputation for being the global networking standard, purely because of its open vendor protocol and its flexibility in terms of accommodating sub-networks such as simple field devices and complex intelligent devices.

Profibus is standardised under the German national standard as DIN 19245, managing to grow significantly over the years, since its inception in 1989.

Over the years, both vendors and users of this technology, had to gather practical experience. Clearly investments have to be made when implementing technology, such as Profibus, especially in system maintenance.Field network communication is likened to living organisms – they change with time. For instance, during the engineering phase the Profibus engineer is expected to produce a design based on the properties of the network participants, allow for expansion capacity and geographical properties of the plant. With time the network will deteriorate due to immediate corrective action(s) taken against communication and peripheral faults that occur during the operation phase.

After a few years you find that the original design and the actual configuration are two different networks. This is one of the practices that contributes to the sluggish transition of plants from analogue to digital field communication technology.

I find it odd that other technology sectors have assumed an almost “natural transition from analogue to digital, specifically the Telephony Industry and Photographic and Audio Storage Media technologies. Why is there a fear of embracing digital communication technology in our sector? One could argue that the lifespan of a plant and that of a cassette tape are two very different periods and hence it takes longer for the transition to occur – point taken, but when an opportunity avails itself grab it with both hands as the benefits outweigh the risks.

When we look at maintenance, both skill and tooling play an inseparable key role. Profibus networks require the use of software based tools for diagnosis and verification, but like all software it requires regular usage since it is easy to forget how the tool is used. The challenge that technicians face is that they qualify for a specific Profibus troubleshooting course and are expected to perform miracles when the network fails. The truth is, by the time the network fails they have difficulty using the software as a diagnostic tool

as they have forgotten how the tool operates or how to interpret the data. Endress+Hauser Profibus experts are exposed to Profibus Network faults on a regular basis, allowing us to offer the expertise, both skill and tooling, should the requirement arise to restore the network to its design standards.

Coupled with our process instrumentation know-how Endress+Hauser have a service portfolio referred to as Field Network Audit (FNA). This entails a complete verification report of existing Profibus Networks, followed by a recommendation report.

Since the inception of Profibus, the nature of available tooling was limited, as was the experience that went with it. Today’s tooling allows for predictive maintenance on Profibus Networks. Another reason to consider field networking communication!

AFRICA in FOCUS

Needless to say, most of us have reset our budgets. And 2013 is ready to be measured and reported. The results and difficulties of last year are forgotten, with the new challenges in 2013, already occupying our daily actions. Endress+Hauser South Africa had an excellent year in 2013 and we achieved growth in excess of 20% for the South African operation. Again, we have confirmed that we are the undisputed leader in the fields of Industrial Instrumentation and that many customers believe in our value proposition, products, services and solutions. Where did Africa end up in the scheme of things?Africa Key Achievements:• Africa Overall Growth exceeded 40% of Target• Africa Projects Growth exceeded 158% of TargetEndress+Hauser’s Africa aggressive growth target of 30% for 2013 is testimony to the commitment and drive of both the Endress+Hauser Management Team and the actions and commitments of our partner teams deployed in Africa. The Endress+Hauser team is geared for the challenge and we will be focusing on Operational Excellence, which involves initiatives like; Key Client Development (with Evan Dent), Pricing and Contract initiatives, Training (both our teams and clients alike) and a focused Vertical Market drive in all the key verticals i.e. Oil and Gas, Water, Waste water and Mining, F&B and Power Generation. Over and above these initiatives, our partner programme will be strengthened, re-aligned and restructured, a re-seller tier will be trialled in areas where we are considering Business Development and Expansion, and our Client and Customer relationships will be revitalized. 2013 will see Endress+Hauser Africa re-focus our goals and objectives, to meet our customer’s needs. I would like to emphasize: OUR CUSTOMERS NEEDS.

This involves a re-think of Endress+Hauser Africa’s strategies and methodologies, our local Endress+Hauser structures of logistics, supply chain and also how we think about our service and support business.For up to date information on the latest Endress+Hauser products and solutions, please consult the Endress+Hauser website at www.endress.co.za or your local Endress+Hauser (per country). The previous editions of Africa-in-Focus have profiled our representatives throughout Africa. In 2013 Endress+Hauser Africa, will see increased visibility and growth in countries such as Uganda, Angola, Tanzania, Kenya, Mozambique and the Democratic Republic of the Congo. Together with the Marketing Team, we have a lot of ground to cover and 2013 is set to become very interesting.

Analysis in simple terms

Lesson 1: pH measurement

Understanding the in and outs of liquid analysis is no simple task. In each issue of the wazzup, a measuring principle or method of operation will be explained in layman’s terms for non-experts.

Why do customers even want to measure the pH value?The pH value provides information about the behavior of a liquid. The easiest way to understand this is by a change in the taste: acids taste sour while alkalis have a soapy taste. Both acids (pH value below 7) and alkalis (pH value above 7) can destroy and “dissolve” materials, such as skin, clothing, lime and metals. Our customers’ processes also hinge on maintaining a correct pH value. Examples: • A neutral pH value of 7 is critical in the

outlet of wastewater treatment plants (WWTP) so as not to present a threat to fish and plant life in our lakes and rivers.

• Minor changes in the pH value can affect the effectiveness of drugs or vaccines.

• In plastics production, the pH value is measured to rule out any changes to the properties of the plastic, such as brittleness or changes in colour. The well-known litmus test is based on this specific effect.

• How is the pH value measured?The pH value depends on the concentration of H+ ions in the liquid (ions are electrically charged particles). The more H+ ions there are, the lower the pH value. In all types of pH

value measurement, the sensors “count” the H+ ions and use the results to

calculate the pH value.

In the case of glass electrodes, the H+ ions gather on the outside of the glass and in doing so change the charge. The sensor compares this charge with the reference liquid inside the sensor. You can imagine it to work like a kind of battery, with a voltage between the two poles. The difference in charge is used to calculate the number of H+ ions and ultimately the pH value.ISFET sensors do the same, but instead of using a glass membrane they work with a microchip which reacts specifically to H+ ions. A reference liquid inside the sensor is also required here as a reference value.

What criteria do I use to select the sensor (and related transmitter and assembly) to suit my application?This depends on a variety of factors in the process. Does the sensor need to be shatter-resistant (e.g. for the food industry)? Be cleaned in place? What pH values must it be able to measure? Should it be immune to particles, oil and dirt? What pressures occur in the process? What temperatures must the sensor and assembly withstand? Are special certificates and approvals required?The pH Selection Guide is a great help for selecting the right solution for the complete pH measuring point. It can be ordered with SAP number 71114029.
