The freedom to think long term.

For more than 25 years, consumption data have been determined precisely and transmitted by radio. Data in the "cloud" and "big data" change the Metering world.


We travel by train instead of flying and eat more vegetables than meat to improve our personal ecological footprint. However, making the footprint of metal processing plants “greener” takes much more effort than that.


People sit up to 18 hours in an aircraft. How can light contribute to the passengers' wellbeing? How can flying be made an experience?

Companies deal differently with the requirements of the digital world. "We do not want to participate half-heartedly in digitization but take advantage of the opportunity," Sina Seebach says. "Our products as well as our workplaces are to reflect digital transformation."

Harmonization of the IT world is the first of many necessary steps. "Future-oriented ideas require modern IT tools which our employees like to use," the project manager declares. "The new, standardized working world enables us to ensure internal cooperation but also communication with customers and partners worldwide."

When energy providers read off smart meters in households today, this is in many cases done precisely by automatic meter reading. The measurement results can then be called up from a system platform and processed further.

"Four our customers, we want to be a system supplier. We not only offer products but comprehensive solutions where products and services complement each other." Sina Seebach explains.

"The energy consumption of an accommodation unit or a city district can thus be determined precisely and optimized. Smart metering, the smart use of energy, helps our customers to make better use of energy. Climate also benefits from that," Sina Seebach adds. 

Smart cities will in the future be supplied with water, heat, gas and electricity via interconnected consumption meters providing smart measurement and control. With digital and secure solutions from Diehl Metering, energy supply is ready for the Internet of Things.

Improve the process – Save energy

How can we obtain an overview of all the consumption data required during ongoing production? The first step of energy management is effective energy controlling: Ongoing consumption must be monitored exactly: The cause must be researched wherever specific upturns are seen. Meter data is prepared to assign it exactly to the individual energy consumers. Energy management creates the prerequisites for responsible, conscientious and economical handling of energy, to continuously improve the ecological footprint of our metal production.

This year's objective? Handling materials more efficiently and sustainably than we do today.

“We have always been conscious about our environment and costs” says Camille Kielwasser from Central Services at Diehl Metall in Röthenbach. “We basically never had open doors to the boiler room and we installed motion sensors on lamps that were always on. But that is not what we mean, when we talk of energy management. For example, we are working on reducing the energy expended and the material used in the individual processing stages of production.”

This means rethinking and optimizing the entire production process time and again. “The high number of over 100 different alloys and a wide spectrum of semi-finished product formats and dimensions make recording and accurate assignment to products very difficult. This is a giant task”, acknowledges Dr. Claus Heubeck, Manager for Energy and responsible for the purchase of energy for the entire Diehl Group. More and more meters were installed at Diehl Metall in Röthenbach for this purpose, which recorded the consumptions in real time and routed it to an evaluation system. This enables production heads to effectively monitor the energy consumption of their plants. Managing energy with continuously improving transparency, is the task.

"Time and again we find new adjusting screws which we must turn to improve a bit every year", Camille Kielwasser says. "This year we plan to reduce waste heat losses. The hot-water basin into which the brass rods are immersed after pickling will be provided with a flexible cover swimming in the basin during breaks in production. This will have two effects: water losses will be reduced and energy will be saved as the water temperature is maintained.

Light Verification Center

The Light Verification Center of Diehl Aviation has a floor space of more than 1000 sq m. It is the largest facility of its kind in Germany where the effect of light in aircraft cabins is tested. Passengers are to constantly feel comfortable during up to 18 hours of flight. "Cabin lighting is of great importance for a person's biological clock, and the service crew uses lighting to structure the flight phases. That means for us: every flight phase must have appropriate cabin lighting," Dirk-Achim Schevardo explains.

Depending on the respective cultural origin, light is perceived in different ways and so we adapt it to the airline’s wishes: "Scandinavian airlines like warm, bright light; in the Asian region, cooler, bluish light is preferred" Schevardo describes the different tastes. In this context, the surfaces reflecting the light are decisive. "We try to "paint by light": that means all surfaces should be illuminated evenly."

In top-of-the-range aircraft construction, designers use select materials and want to stage them appropriately. Dirk-Achim Schevardo remembers a customer who wanted to accentuate a particular kind of wood veneer: "However, dark wood absorbs a huge amount of light and thus requires a specially adjusted light source. We see ourselves as a link between engineers, designers, marketing experts and businessmen. This is of particular importance if the customer cannot describe his problem in detail."

Aircraft Projection System

  • Diehl Aviation regularly shows at exhibitions what is possible in aircraft cabins:  

Diehl Aviation is known as a supplier with highest quality standards. This is what matters in our sector: “It is important to us that lights can be replaced rapidly and our high quality standards ensure a low failure rate. Nevertheless, we want to sell the light effects in the cabin, not the technology as such or individual lamps. The amount of effort we spend on that guarantees the best results for our customers.” 

In order to show the multiple effects of light in the cabin, our employees check the customer's requirements in detail: "Light can make flying an experience again. We offer design workshops to show what is possible. In the cabin roof or in a light dome, we make emerge a starry sky, the airline's logo or duty-free products. 

The success of Diehl Aviation proves us right: “All Airbus aircraft and almost the entire Boeing aircraft family are equipped with Diehl lighting systems,” Dirk-Achim Schevardo proudly states.
