Background
Residential water infrastructure in Sweden is steadily moving toward smarter, more automated metering systems. For distributors, the priority is no longer only measurement accuracy, but also operational efficiency and long-term data reliability.
In 2025, DEAZESU supported a Stockholm-based water meter distributor in a residential smart metering pilot project, supplying 3,200 ultrasonic water meters (DN15–DN25) across multiple housing applications. The deployment included both brass and composite body versions to accommodate varied installation environments.
The pilot focused on enabling remote meter reading and leak detection, supporting the transition toward more digitalized residential water management.
The Challenge
The distributor faced several practical constraints typical of residential smart metering rollouts.
Manual meter reading across dispersed residential units created operational inefficiencies, while inconsistent reading cycles often impacted billing accuracy. At the same time, early-stage leak detection requirements were becoming more important as building operators sought to reduce water loss and maintenance costs.
Key project challenges included:
- Dependence on manual or semi-manual meter reading processes
- Need for remote meter reading capability (AMR readiness) to reduce labor intensity
- Requirement for early leak detection to improve system responsiveness
- Ensuring consistent installation across multiple residential buildings
- Managing phased delivery across a multi-quarter rollout schedule
- Maintaining stable measurement performance under varied installation conditions
The distributor needed a solution that could unify measurement reliability with future-ready data communication capability, without adding complexity to field operations.
The Solution
DEAZESU supplied integrated ultrasonic water meters designed for residential smart metering applications, covering DN15–DN25 sizes.
The solution focused on combining stable ultrasonic measurement with deployment flexibility.
Core Product Advantages
- Ultrasonic measuring principle ensures stable performance without moving mechanical parts
- AMR-ready design supports future remote meter reading system integration
- High sensitivity flow detection supports leak identification at low flow rates
- IP68 protection class suitable for demanding installation environments
- U0/D0 installation flexibility allows installation in any orientation
- LED display interface simplifies on-site verification and maintenance
- Compliance with ISO 4064 standards
Technical Overview (DN15 model example)
| Parameter | Specification |
| Nominal Diameter | DN15 (15 mm) |
| Flow Range | Q3 = 2.5 m³/h |
| Starting Flow | 2.08 L/h |
| Accuracy Class | R400 |
| Pressure Loss | ≤0.063 MPa at Q3 |
| Connection | BSP G3/4B threaded |
| Protection | IP68 |
These specifications support stable measurement across typical residential consumption patterns while maintaining responsiveness at low flow conditions—an important factor for leak detection performance.
Project Results
The pilot was completed through phased deliveries between the first and third quarters of 2025.
The distributor reported that the supplied meters integrated smoothly into the installation schedule and supported efficient deployment across participating residential properties.
Project outcomes included:
- Stable product supply throughout multiple delivery stages
- Consistent installation experience for field technicians
- Reliable compatibility with the planned remote reading system
- Flexible product selection using both brass and composite body designs
- Simplified inventory management through a unified ultrasonic platform
Although the project focused on evaluation rather than large-scale rollout, the deployment demonstrated that ultrasonic water meters could provide a practical foundation for future residential smart metering expansion.
The combination of installation flexibility and remote-reading readiness helped simplify project implementation without introducing unnecessary complexity.
Customer Feedback
The Swedish distributor emphasized the importance of dependable product quality and coordinated delivery during the pilot.
“Having both brass and composite options with the same operating concept made product selection much easier across different residential projects.”
The feedback reflected practical project priorities rather than isolated product specifications, highlighting the value of reliable manufacturing and consistent supply during phased deployments.
Conclusion
Residential smart metering projects require more than accurate measurement. Distributors and utilities also depend on dependable product availability, installation consistency, and solutions that fit existing deployment plans.
This Stockholm pilot demonstrated how DEAZESU’s ultrasonic water meters supported those objectives through a combination of ultrasonic measurement technology, flexible housing options, and AMR-ready capability.
Rather than introducing unnecessary complexity, the project focused on selecting equipment that aligned with practical installation needs and long-term smart metering development.
As utilities continue expanding digital water infrastructure, manufacturers capable of delivering reliable products together with stable production and responsive technical support remain valuable partners throughout every stage of deployment.
