Heat and cooling energy measurement.

Thermal energy meters measure the actual heat or cooling energy transferred in heating, cooling, and energy supply systems. They measure the medium’s volume flow and the temperature difference between the supply and return lines, using these values to precisely calculate the energy consumed. They are used in residential and commercial buildings, district and local heating networks, data centers, and industrial applications, providing the basis for transparent consumption measurement, efficient energy management, and usage-based billing.

The importance of thermal energy measurement is continuously increasing as energy efficiency requirements, building decarbonization, and digitalization continue to advance. In particular, thermal energy meters enable fair allocation of heating and cooling costs according to actual consumption in submetering applications. At the same time, they provide valuable data for optimizing energy flows and support compliance with regulatory requirements such as the European Energy Efficiency Directive (EED).

Sontex thermal energy meters provide reliable and precise solutions for measuring heating and cooling energy across a wide range of applications. The portfolio includes modern ultrasonic and compact energy meters as well as flexible system solutions for residential property management, commercial properties, energy utilities, and industrial applications. High measurement accuracy, long-term stability, and a wide range of nominal sizes and configurations enable applications ranging from individual apartment meters to demanding heating and cooling network installations.

Thanks to integrated or optionally available communication interfaces such as Sontex Radio, Wireless M-Bus (wM-Bus) / OMS®, LoRaWAN®, M-Bus, and other standard protocols, the energy meters can be seamlessly integrated into smart metering, energy management, and building automation systems. Extensive memory functions, automated data collection, and modern security mechanisms ensure transparent and traceable consumption measurement. This provides building owners, operators, metering service providers, and energy utilities with a future-proof solution for the digital measurement and billing of heating and cooling energy, as well as for the sustainable optimization of their energy systems.
