Reliable data for ESG, CSRD, and sustainability reporting
Turn outdated meters into a transparent data source, without replacement.
When ESG auditors ask for consumption data and you’re piecing it together from five different sources, it’s time for a change. New reporting frameworks such as CSRD, EED, and SFDR demand accurate, frequent, and consistent data. Yet most buildings still rely on outdated meters, each of a different type, often without remote access. The risk? Delays, errors, and reputational damage. ACRIOS provides a way forward.
Common challenges in ESG reporting
Our solution
ACRIOS converters retrofit existing meters, digitalising them instantly, without costly replacements. They provide automated, secure, and frequent readings, ensuring that your data is consistent, reliable, and audit-ready.
ESG benefits
- Waste reduction by reusing existing meters
- Lower CO₂ emissions through fewer site visits
- Energy savings thanks to low-consumption ACR-CV devices
- Early leak detection and anomaly alerts
- Safer workplaces (no manual readings in hazardous areas)
- Better tenant/customer experience with transparent billing
- Digitalisation without operational disruption
- Automated, auditable consumption records
- Precise reporting in line with EU directives
- Encrypted data transmission via NB-IoT (licensed bands)
- Proven in practice (testimonial)

"The remote gas meter reading devices from ACRIOS have proven their reliability and quality of workmanship. We appreciate that all our technical requirements were met and that we received all the necessary documentation and technical support for integration into our information system. We are very satisfied with the cooperation..“
ACRIOS was instrumental in our success on a large-scale European deployment of the wM-Bus concentrators, helped to solve all of the technical challenges and deliver results within the set deadlines.
“The ACRIOS scripting capabilities have provided Netmore with the required solution for solving integrations with MBUS/MODBUS units.”
We successfully integrated the ACRIOS Data Concentrator into our smart metering project, seamlessly connecting hundreds of meters. The device’s performance and stability have been outstanding, even in challenging environments. The LoRaWAN protocol used by the concentrator ensures strong, reliable signal coverage, even in hard-to-reach areas. We highly recommend the ACRIOS Data Concentrator to anyone looking to enhance their smart metering infrastructure.
“We were searching for a way that would allow us to connect existing M-Bus and MODBUS meters to our LoRaWAN network and found the solution provided by ACRIOS valuable for these use cases.“
