Modular High-End Solutions.

Calculators are the central element of modern heat, cooling, and energy meters. They acquire measurement values from flow and temperature sensors, use these values to calculate the actual heat or cooling energy consumed, and provide the data for billing, monitoring, and energy management. By processing, storing, and transmitting measurement data to higher-level systems, calculators are used in residential and commercial buildings, district and local heating networks, and industrial energy applications, forming the basis for reliable and transparent energy measurement.

As requirements for energy efficiency, digitalization, and building automation continue to increase, the importance of high-performance calculators is growing steadily. They not only enable precise measurement of energy consumption but also provide valuable data for optimizing energy flows, monitoring systems, and implementing modern smart metering concepts. At the same time, they support compliance with regulatory requirements and provide the basis for transparent, usage-based consumption measurement.

Sontex calculators offer high-performance and future-proof solutions for measuring, processing, and transmitting consumption and energy data in heating, cooling, and combined energy applications. Thanks to their modular design, high flexibility, and extensive expansion options, they are suitable for a wide range of requirements – from residential and commercial properties to district heating networks and demanding industrial applications. Support for various flow sensors and additional utility meters enables customized integration into individual metering and energy concepts.

With extensive communication interfaces such as LoRaWAN®, Wireless M-Bus (wM-Bus) / OMS®, Sontex Radio, M-Bus, Modbus, BACnet, NFC, and an optical interface, the calculators can be seamlessly integrated into smart metering, energy management, building automation, and district heating systems. Features such as data logging, tariff management, flexible expansion options, and convenient configuration capabilities provide the basis for efficient consumption measurement and modern energy management. Sontex calculators therefore provide a powerful platform for precise measurement, transparent billing processes, and the digitalization of energy infrastructures.
