This is a question that often comes up in smart metering projects, but perhaps it is not the right question to ask, because battery life is not an intrinsic characteristic of the meter.

It is the result of the interaction between technology, service configuration and actual operating conditions.

Yet, tender specifications and procurement requirements often include statements such as: “Battery life: at least 13 years”, without clearly defining the conditions required to achieve this target.

The reality is that two identical meters, equipped with the same battery and the same firmware, can have very different service lives.

Why? Because battery life depends on many factors

✅ Battery capacity
✅ Hardware efficiency
✅ Firmware optimisation
✅ Application protocol used
✅ Reading and transmission frequency
✅ Number of alarms and additional communications
✅ Radio coverage quality
✅ Installation conditions
✅ Evolution of the cellular network over time

One aspect that is often underestimated is the application protocol.

Not all protocols have the same impact on energy consumption: some are more verbose and energy-intensive than others. The more messages are exchanged, the more data are transmitted, and the longer the modem remains active, the higher the energy consumption. The choice of application protocol therefore has a direct impact on battery life.

The most important point, however, concerns NB-IoT connectivity

Unlike local radio technologies such as wireless M-Bus, an NB-IoT smart meter is part of an end-to-end solution involving at least three key players: the meter, the platform collecting the data, and the mobile network operator carrying the communications.

The overall performance of the system depends on all three.

The cellular network, in particular, is a dynamic infrastructure: it evolves over time and is continuously optimised, reconfigured and upgraded. Coverage, radio parameters and frequency usage can all change.

Many tender specifications and SLAs are written as if the radio conditions on day one will remain identical fifteen years later. Yet anyone—even someone new to smart metering—knows this is not the case: we have all experienced how mobile network performance can vary over time simply by using our smartphones.

The NB-IoT network is not a constant. It is a variable.

All these factors can influence the device’s energy consumption throughout its lifecycle.

This does not mean that the battery life of a smart meter is unpredictable or that the manufacturer is simply a passive observer. On the contrary, a significant part of the device’s service life is determined by the design choices made before the meter is ever installed in the field.

At Maddalena, we have worked on several strategies with one straightforward objective: to make the meter as resilient as possible to real-world operating conditions, optimising its efficiency across the different conditions it may encounter in the field.

Perhaps, then, the right question is not: “Will the meter last 13 years?” but rather: “Which operating conditions have been considered, and which measures have been adopted to maximise the likelihood of achieving those 13 years?”

For this reason, when evaluating an NB-IoT smart meter, battery life should always be associated with a clearly defined operating scenario: transmission frequency, application protocol, radio coverage, alarm management and installation conditions.

Only then does the figure become comparable across suppliers and genuinely useful in a technical specification or purchasing decision.

Because a declared battery life without reference conditions is just a number.

A declared battery life together with its operating conditions is a technical requirement that can be measured and verified.

And ultimately, battery life is not guaranteed simply by using a larger battery.

It is engineered by designing a system capable of making better use of every available joule.

Field experience drives innovation

This is the approach behind ElecTo SONIC, Maddalena’s ultrasonic smart meter, which has surpassed 500,000 installed units.

A milestone that goes beyond commercial figures: it reflects the field experience gained by a technology used every day by a growing number of utilities. This experience is what drives its continuous evolution, turning operational needs identified in the field into new features and increasingly advanced performance.

ONE PLATFORM, MULTIPLE TECHNOLOGIES
Different metering technologies.
One digital experience.

The experience gained with ElecTo SONIC continues to drive the development of the ElecTo (Electronic Totalizer) platform, now also adopted by Maddalena across other metering technologies, such as ElecTo MVM and ElecTo SJ. This approach allows utilities to choose different metering principles while maintaining continuity across the digital platform and its functionalities.

In ElecTo SONIC, these principles have been translated into specific design choices aimed at ensuring metering stability, mechanical robustness, operational continuity and data availability throughout the meter’s entire lifecycle.

The ultrasonic measuring principle enables consumption to be measured without any moving mechanical components and helps maintain stable metering performance over time, with no deterioration due to product ageing. The brass body also ensures high mechanical robustness under varying installation conditions, while the high and constant sampling rate, both day and night, combined with IP68 certification for up to 1,440 hours, enhances the meter’s ability to withstand demanding field conditions, including environments subject to flooding.

The communication system has been designed according to the same reliability-driven approach: the separate multiband antenna maximises signal radiation and improves transmission performance, while the NFC interface provides quick access to configuration and local diagnostics. The integrated data logger, capable of collecting data for over twenty years, also provides utilities with a valuable source of information for statistical analysis, consumption monitoring and a better understanding of how the network evolves over time.

To maximise battery life in LoRaWAN and NB-IoT configurations, Maddalena has implemented the latest versions of communication standards and state-of-the-art hardware components, optimised for both transmission performance and power consumption. Battery life thus becomes the result of an integrated design approach, consistent with the goal of ensuring operational continuity and reliability throughout the smart meter’s entire lifecycle.

Truly scalable multi-protocol communication

The sector is progressively shifting from an AMR (Automatic Meter Reading) model, based on short-range radio readings primarily used for billing purposes, to an AMI (Advanced Metering Infrastructure) model, where data is collected daily via long-range technologies and becomes a valuable tool for monitoring and managing water resources.

In this scenario, each utility can choose the infrastructure best suited to its specific context, primarily LoRaWAN or NB-IoT. However, relying on a single communication channel can create dependency on a fixed network, often managed by third parties, which may be affected by outages, technological changes, decommissioning or contractual changes over the meter’s lifetime.

For this reason, ElecTo SONIC integrates a secondary Wireless M-Bus link even in long-range architectures, providing a true fallback strategy. While the LoRaWAN + Wireless M-Bus combination is now widely available on the market, the NB-IoT + Wireless M-Bus fallback configuration is a distinctive feature of Maddalena’s solution, designed to protect the investment and ensure continuous access to data even in the event of issues with the primary network.

A significant example is the recent project carried out with Acque Bresciane, which led to the installation of over 36,000 ElecTo SONIC meters as part of its water network digitalisation programme. This successful project confirms the platform’s reliability even in large-scale deployments.

DESIGNED TO EVOLVE
The true value of a smart meter lies in its ability to evolve over time

The experience gained from over half a million installations continues to drive the evolution of ElecTo SONIC, with new features developed to meet the evolving operational needs of utilities.

Key enhancements currently available include:

• metrological certification up to R1000, further improving accuracy at low flow rates;
• MID-certified reverse flow measurement, enabling the detection and measurement of any reverse flows;
• availability in MID Accuracy Class 1 for applications requiring higher metrological performance;
• T70 temperature class, available on request;
• bacterial growth alarm, based on water temperature monitoring to detect and signal conditions that may favour bacterial growth;
• NB-IoT interface with Wireless M-Bus over NB-IoT communication protocol (EN 13757-8:2023) and Wireless M-Bus fallback, a distinctive feature compared with NB-IoT-only solutions available on the market, designed to ensure continuous access to data even if the primary network is unavailable.

For utilities, this means access to even more reliable data, improved billing accuracy, timely detection of anomalies, and increasingly advanced tools for network management.

READY FOR THE FUTURE
New regulatory requirements, new features, the same reliability

Innovation also extends to materials intended to come into contact with drinking water. The evolving European regulatory framework introduced by the Drinking Water Directive (EU Directive 2020/2184) is setting increasingly stringent requirements for the safety and compliance of materials used in water supply networks.

To address these evolving requirements, ElecTo SONIC is also available in a lead-free brass version, with a lead content below 0.1%, providing utilities with a solution already designed to meet future regulatory requirements while helping protect the value of their investment over the long term.

A roadmap for continuous innovation

Surpassing 500,000 installations is not an endpoint, but a solid foundation for continued innovation. The ElecTo SONIC roadmap includes further developments aimed at expanding interoperability and communication protocols, diagnostic capabilities, remote management and integration with utilities’ digital ecosystems, reinforcing Maddalena’s commitment to the continuous evolution of the platform.

At the same time, Maddalena is completing a Life Cycle Assessment (LCA) study in preparation for the publication of an Environmental Product Declaration (EPD), which will be available soon and will provide utilities with transparent, verified environmental information covering the product’s entire life cycle.

Innovation means ensuring continuity

In the water sector, a meter remains part of the network for many years. This is why the true value of a smart meter lies not only in the performance it delivers today, but also in its ability to evolve over time.

With over 500,000 ElecTo SONIC meters installed, Maddalena confirms the strength and reliability of its offering in the ultrasonic smart meter segment. The experience gained in the field continues to drive the evolution of the ElecTo platform, now also available across the MVM and SJ product families, giving utilities the freedom to choose the metering technology best suited to their needs while benefiting from a common, stable and continuously evolving digital platform.

Metering technologies may differ. Utilities’ needs evolve over time. The digital platform supporting them must ensure continuity, reliability and the ability to evolve alongside their networks. This is the vision driving the development of ElecTo SONIC and, more broadly, the entire ElecTo platform.

On 25 June, Maddalena took part in the 11th edition of Servizi a Rete TOUR, held at the Stazione Leopolda in Florence and organised by Servizi a Rete in collaboration with Publiacqua.

A key event for the Italian water sector and an important opportunity for utilities, water operators, companies and professionals to discuss the transformations currently shaping the industry: digitalisation, smart metering, remote reading, data quality, infrastructure resilience and sustainability.

These topics are becoming increasingly interconnected, changing not only the technologies deployed in the field, but also the way water networks are understood, monitored and managed.

Smart metering and remote reading: the experience of AMAP Palermo

During the session dedicated to smart metering and intelligent consumption management, Alessandro Senatore, Maddalena’s Sales Manager for Central and Southern Italy, joined Sandro Ferrito, Head of the Warehouse, Standardisation and Testing Unit at AMAP Palermo, to present the water utility’s experience in digitalising its meter fleet.

AMAP, the integrated water service operator for the Metropolitan City of Palermo, has launched a major digitalisation programme, progressively extending the use of smart meters to a large number of the municipalities it serves.

The project, divided into three geographical lots – Palermo, Western Area and Eastern Area – is part of a broader programme that also includes maintenance and upgrading works on the water network and service connections. A concrete example of how the digital transformation of water services increasingly relies on the availability and intelligent management of data.

From meter to data: a new model for network management

Smart metering is changing the role of the meter itself. Periodic, manual consumption readings are being complemented by more frequent and accurate information, enabling remote reading, consumption monitoring, early detection of anomalies and greater measurement accuracy.

The meter thus becomes a true network sensor: a tool capable of generating valuable data to support operational efficiency, improve service quality and contribute to more responsible management of water resources. In this context, measurement quality and data quality are becoming increasingly interconnected.

ElecTo SONIC: technology and interoperability for smart metering

This is where ElecTo SONIC comes into play: Maddalena’s ultrasonic water meter with integrated electronic clock and multi-protocol radio.

The solution enables remote reading through both mobile and fixed systems, with the aim of ensuring interoperability and continuous data availability. Its sampling frequency remains constant under different operating conditions, enabling highly accurate reconstruction of consumption profiles and the detection of rapid changes in flow rate, contributing to measurement accuracy and the quality of the information available for network management.

The evolution of smart metering also involves the ability of technologies to meet utilities’ changing needs over time, including those related to materials, sustainability and the regulatory framework. ElecTo SONIC is also available with a lead-free brass body, in preparation for the evolving requirements introduced by the European Drinking Water Directive (DWD), which will become fully applicable from January 2027.

Digitalisation and sustainability: increasingly interconnected paths

The experience shared in Florence highlights another important aspect: innovating water metering means looking beyond individual technologies.

Alongside the performance of metering systems, reliability, information security, environmental impact management, protection of people and governance throughout the value chain are becoming increasingly important.

This is an approach that Maddalena pursues through its Integrated Management System and the voluntary sustainability programme launched in 2020, which also includes Sustainability Reporting and the EcoVadis assessment (Silver Rating in 2025).

In the world of Utilities and critical infrastructure, digitalization – smart meters, IoT, and data platforms – has multiplied value and opportunities. But it has also expanded the attack surface.

Today, cybersecurity is no longer a downstream technical requirement: it is a strategic choice that directly affects service continuity, regulatory compliance, and the trust of end users.

For Maddalena, security has always been an integral part of how we design, develop, and deliver intelligent metering solutions. Not as a reaction to the threats of the moment, but as a structural, long-term commitment.

Certified Security, Embedded in the Product

Maddalena has adopted an Information Security Management System (ISMS) certified to ISO/IEC 27001:2022, covering not only information protection and operational continuity, but the entire lifecycle of software and technological solutions.

In practical terms, this means:

• Secure by design across firmware, software, and platform development

• Systematic and documented risk management

• Technical, organizational, and procedural controls aligned with the highest international standards

Regulatory compliance as a driver of trust and reliability

In a rapidly evolving regulatory landscape, compliance is an enabling factor, not a constraint:

• GDPR for the protection of personal data

• NIS2 for the security of networks and information systems

• Alignment with the principles of the Cyber Resilience Act and RED / RED DA regulations for connected products

This approach strengthens trust among Utilities, partners, and stakeholders across the entire value chain.

IT Architectures Designed for Continuity

Digital resilience also depends on infrastructure:

• High availability and redundancy of critical systems

• Segmentation of IT/OT networks

• Enterprise-grade backup and disaster recovery.

The objective is clear: operational continuity, data integrity, and the ability to respond effectively even in complex scenarios.

People, Processes, and Culture

Technology alone is not enough. Maddalena invests in specialized expertise — including IT/OT cybersecurity, risk management, governance, and compliance — as well as in continuous training, because digital resilience is built through the integration of people, processes, and technologies.

A Message to the Utility Sector

In the smart metering context, choosing a supplier no longer means evaluating metrological performance or functionality alone.
It means asking the right questions:

• How secure is the solution over time?

• Is it ready for future regulatory requirements?

• Does it truly protect the Utility’s data, services, and reputation?

Raising the bar in supplier selection means reducing systemic risk and building stronger, more sustainable, and more reliable digital infrastructures.

For Maddalena, protecting systems means protecting value, innovation, and trust. A concrete commitment to supporting Utilities in their digital transition — securely.

With Decree No. 219 of 26 November 2025, which entered into force in January 2026, the regulatory framework governing metrological controls of water meters has been substantially updated, introducing a simplification that will have concrete effects across the entire market.

From an operational perspective, the first impact is a reduction in regulatory complexity. The elimination of distinctions between mechanical, static and venturi-type water meters allows operators and utilities to work within a clearer and more uniform regulatory framework, simplifying the planning of verification activities and reducing the risk of inconsistent interpretations.

A single verification deadline makes the management of the meter fleet more straightforward and facilitates coordination among operators, suppliers and inspection bodies.

The extension of the verification interval also has a direct impact on asset management strategies. With longer cycles, planning can no longer rely solely on regulatory deadlines, but requires greater attention to long-term metrological quality, performance stability and data reliability throughout the entire life cycle of the water meter.

In this context, the ability to maintain consistent performance over time becomes a key factor in ensuring operational continuity and service quality.

From a cost perspective, the new framework may translate into a reduction in operational burdens related to periodic verifications, with fewer field interventions and a more efficient use of resources. However, this benefit is real only if supported by measuring instruments designed to last over time and to ensure accuracy and reliability even across longer time horizons.

Another relevant effect concerns the positioning of technologies in the market. As regulatory differences between the various solutions are removed, competitive value increasingly shifts from the type of meter to the overall quality of the measurement system.

Stability, robustness, data protection and the ability to support advanced network management become distinguishing factors, in a context where measurement is increasingly a strategic tool for operational efficiency and water resource management.

Finally, the extension of verification cycles also fits coherently within a sustainability perspective. Fewer replacements and fewer interventions mean a reduction in environmental impact, greater process efficiency and more responsible infrastructure management. In this sense, the decree represents not only a technical update, but a step towards a more rational, long-term-oriented management model.

For the market—and for companies like Maddalena operating along the water metering value chain—the new regulatory framework therefore represents an opportunity to rethink the value of the water meter not as a simple device, but as a strategic asset, capable of combining reliability, efficiency and sustainability over time.
