DLMS UA Announces Release of Water Smart Meter (WSM) Generic Companion Profile
DLMS UA is pleased to announce the release of the Water Smart Meter (WSM) Generic Companion Profile (GCP), the newest addition to the growing suite of DLMS Generic Companion Profiles.
The availability of the WSM GCP is a milestone achievement. It is set to be the first-ever standardized data model and format for water meter data exchange to be adopted by IEC. It defines the technical, functional, and security requirements of smart water meters within the DLMS/COSEM framework and provides clear guidelines for implementation and certification. With this release, utilities can now ensure secure, reliable, and interoperable data exchange across devices and systems.
The WSM GCP resolves some of the most pressing issues facing the water industry by defining a standardized data exchange model and format, ensuring devices from any manufacturer can communicate seamlessly. It incorporates essential data protection features to safeguard sensitive consumption and operational data. It is also one of the most efficient data models, with push message, pre-established clients, compact data frames and compression mechanisms minimizing battery consumption. Finally, it supports standardized a certification process that reduces deployment complexity and risk.
Key benefits of the WSM GCP include:
- Certified Interoperability – All devices implementing the WSM GCP are tested for compatibility, ensuring interoperability within the water smart metering ecosystem simplifying utilities supply chain. DLMS UA’s rigorous certification process reduces the need for expensive, bespoke certification platforms.
- Legally Relevant Data Sharing – Provides metrology-relevant data, ensuring compliance with legal metrology requirements.
- Enhanced Security – Incorporates robust data protection mechanisms under the DLMS/COSEM framework, safeguarding sensitive data and protecting operations against cyber threats.
- Telecommunication Agnostic – The WSM GCP operates independently of telecommunication technologies, ensuring secure, reliable, and interoperable data exchange across all current and future networks. It currently supports 4G/LTE-NB, LoRaWAN, LPWAN, Wireless M-Bus and will evolve and integrate additional communication technologies in the future.
- Global Standardization – The WSM GCP provides a globally recognized framework, that is set to be the first IEC-adopted standard for water smart meters, helping manufacturers and utilities avoid fragmented national or regional approaches.
This release demonstrates our commitment to making DLMS the global language for interoperability across all utilities, now including the water sector.
