Thermal energy meters (TEMs)
Energy cost billing — easier than ever before
Belimo's certified thermal energy meters (TEMs) meet the requirements of EN 1434 and have type approval for thermal energy 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 invoicing.
The TEMs are also available without approval. They reliably measure energy even when there is glycol in the water. They automatically and continuously measure the glycol content in the medium, compensate for it and, in doing so, ensure reliable ultrasonic volumetric flow measurement. This results in precise determination of the thermal energy. Belimo's TEMs are designed to be multi-application devices, i.e. they can be used as heat meters, cooling meters, or as combined heat/cooling meters — installed in either the return or supply line of the system. The application and installation position are configured during commissioning using a smartphone and the Belimo Assistant 2 app.

HVAC hydronics: The goldmine in energy renovation projects
The smart control of heating, cooling, and ventilation loads has a big impact on building energy efficiency. A key aspect here is the heating and chilled water circuit, i.e. the hydronics of a building.
Generation
- No energy loss with 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 the energy flow visible.
Zone
- Demand-driven zone control.

Bringing together what belongs together
High-quality measurement
Multi-point wet calibration of TEMs
The new TEMs integrate energy metering and IoT-enabled billing in one device. They provide seamless and direct integration into a building automation system or into an IoT-based monitoring platform with tools for improving performance and recording billing data. We bring together different functional characteristics — so that you can save both time and cost.

Digital support during planning 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 users's energy data makes your work easier.
The TEMs with a Near Field Communication (NFC) interface enable easy commissioning, configuration, and maintenance directly from a smartphone. Belimo Assistant 2 allows the TEM to be configured intuitively and enables the commissioning process to be logged. Key performance indicators (KPIs) that provide transparency regarding the meter's status ensure reliable operation. At the same time, numerous diagnostic parameters indicate to the user how the product interacts with the system during ongoing operation. Rapid failure analysis is made possible, should a service call become necessary.
Seamless integration of measurement data
Seamless and direct integration into the building automation and control system and designed for IoT-based energy monitoring and billing — integrating energy data has never been easier. One device provides all the information you need to optimise the overall performance of your system.
Excellent connectivity
The TEMs support all standard communication protocols used in building automation.
Power over Ethernet
Supply power to the device and transmit data simultaneously via a single Ethernet cable, thereby simplifying installation and avoiding wiring errors.
Direct integration into IoT platforms
With Belimo's IoT-enabled products, field devices can be connected directly to modern building IoT platforms. Benefit from the possibilities of a connected digital ecosystem.
Intelligent energy meters connected to the Belimo Cloud
Performance reports
Belimo Cloud reporting provides a comprehensive overview of current and past performance data such as energy consumption and flow rate, as well as an overview of operational warnings or errors.
Web server
The TEMs feature an integrated web server that enables direct data access and makes it very easy to configure settings.
Modular design for rapid meter replacement
The TEM consists of a sensor module (lower part) with connected temperature sensors, which house the processing unit and measuring system, as well as the logic module (upper part), which connects the TEM to the power supply and provides the bus and NFC communication interfaces.
The sensor module is available as a spare part and, in certain countries, must be replaced periodically in accordance with national regulations. To do this, the logic module can be removed (with all cables remaining connected) and the sensor module easily replaced. The logic module is then reattached. There is no need to reconnect any cables or reintegrate the meter into the system. This results in significant time savings!
