Thermal Energy Meters (TEM)
Energy billing made easier than ever
Belimo's certified thermal energy meters meet the requirements of EN 1434 and have type approval in accordance with the European Measuring Instruments Directive 2014/32/EU (MID). They provide validated data for invoicing purposes, which can be used for direct tenant billing. Our thermal energy meters are also available as variant without MID / EN 1434 approval. They can reliably measure energy, even when there is glycol in the water. They automatically and continuously measure the glycol content in the fluid, compensate for it and, in doing so, ensure reliable ultrasonic volumetric flow measurement. This results in precise determination of the thermal energy. Belimo Thermal Energy Meters™ are designed to be multi-application devices, i.e. they can be used as heat meters, cold meters, or combined heat/cold meters. They can also be installed either in the return flow or in the supply flow of the system. The application and installation position are provided to the valve during setup using a smartphone and the Belimo Assistant App or using a laptop and the built in web-server.

HVAC hydronics – the goldmine in building renovation projects.
The smart control of heating, cooling, and ventilation loads has a big impact on the energy efficiency of buildings. A key aspect here is the heating and chilled water circuit, i.e. the hydronics of a building.
Generation
- No energy loss at zero load reduces operating costs.
- Planning reliability as a first step towards better energy efficiency.
Distribution
- Pressure fluctuations in distribution lead to lower power output.
- Making energy flow visible.
Zone
- Demand-driven zone control.

Digitally supported project design and commissioning
Apps and web tools support the design process and offer fast and simple commissioning at your fingertips. A truly digital approach and full transparency on the end usersʼs energy data makes your life easier.
The Belimo Thermal Energy Meter™ with NFC interface (Near Field Communication) enable easy configuration and maintenance directly from a smartphone. With the Belimo Assistant 2, the devices can be configured intuitively and commissioning values can be logged. Key performance indicators, which make it easy to determine the "health status" of the device, ensure reliable operation. Numerous diagnostic parameters show how the device interacts with the system during operation. If servicing is required, it is possible to draw up a failure analysis quickly.
Seamless integration of metering data
Seamless and direct integration to the BMS and equipped for IoT-based energy monitoring and billing. Integration of energy-data has never been easier. One device provides all the information you need to improve the energy performance of your system.
Excellent connectivity
The Belimo Thermal Energy Meter™ has on board all common building automation communication protocols.
Power over Ethernet (PoE)
PoE allows the device to be powered and the data to be transmitted simultaneously via an Ethernet cable. This simplifies installation, avoids wiring errors and eliminates the need for a local power supply.
Direct integration into IoT platforms
Belimo's IoT-ready products allow field devices to be connected directly to modern building IoT platforms. Now you can benefit from the possibilities of a networked digital ecosystem.

Performance reports
Belimo Cloud Reporting provides a complete overview of current and past performance data such as flow, energy consumption, power requirements and delta T, as well as an overview of operational warnings or errors that could impact efficiency.
Webserver
The Thermal Energy Meters have an integrated web server for direct data access and setting options.
Modular design for a fast meter exchange
The Thermal Energy Meter consists of a sensor module (lower part) with connected temperature sensors, which houses the calculator unit and measuring system, and the logic module (upper part), which connects the Thermal Energy Meter to the power supply and provides the bus and NFC communication interface.
The sensor module is available as a spare part and, in certain countries, must be periodically replaced according to national regulations. To do this, the logic module can be separated (leaving all cables connected) and the lower sensor module can be easily exchanged. After that the logic module is clipped back on again. There is no need to re-connect cables or re-integrate the meter into the system. A very significant time-saving!
