Easy Radio Retrofitting.

Retrofit water meters with Sontex MODULARIS or Honeywell/Elster modules for modern remote meter reading and EED compliance.

Radio Modules

Radio modules expand existing water meters with modern communication capabilities, providing the foundation for efficient, digital consumption data collection. They enable the automatic transmission of consumption data to remote meter reading, smart metering, and building management systems without requiring the water meter itself to be replaced. This allows existing metering installations to be modernized cost-effectively and adapted to the requirements of an increasingly connected infrastructure.

As requirements for digitalization, energy efficiency, and automated consumption data collection continue to increase, retrofit solutions are becoming increasingly important. Radio modules allow existing water meters to remain in use while benefiting from modern communication technologies. Consumption data can be collected, transmitted, and analyzed automatically, reducing the need for manual meter reading, improving data availability, and providing the basis for efficient consumption billing and modern water management.

Sontex radio modules offer a cost-effective and future-proof solution for retrofitting compatible water meters with modern wireless communication. They enable the easy modernization of existing metering installations and provide the basis for remote reading of consumption data in residential buildings, commercial properties, and water utility applications. Depending on the model, the modules are available for different water meter platforms and offer a high degree of flexibility when integrating them into existing metering and billing concepts.

With communication options via Sontex Radio, Wireless M-Bus (wM-Bus) / OMS®, or LoRaWAN®, the radio modules can be seamlessly integrated into AMR, smart metering, remote meter reading, and building management systems. They support the requirements of the European Energy Efficiency Directive (EED) and enable secure, reliable, and future-oriented consumption data collection. This provides metering service providers, building owners, and water utilities with a cost-effective solution for the gradual digitalization of existing water meter installations and the transition to smart metering systems.
