Compact residential heat meter, type ELF 2, DN15 (1/2"), Q3=1.5 m3/h, Tmax: 90°C, L=110mm, installation on supply, connection GZ3/4", brass body 69-1047207-000

Compact heat meter for precise energy consumption measurement

This compact heat meter, type ELF 2, is designed to measure thermal energy consumption in heating and cooling systems, particularly in residential, office, and commercial buildings. The device combines a precise flow transducer with an electronic calculator, providing accurate and reliable readings. The construction based on a single-jet flow transducer allows for installation in both horizontal and vertical positions.

Construction and application

The ELF 2 heat meter is characterized by a solid construction with a brass body and is adapted to work with water as a heating medium. Equipped with PT500 temperature sensors, it measures both supply and return temperatures, enabling accurate calculation of energy consumption. Thanks to the ability to cooperate with remote reading interfaces (M-Bus, Modbus) and communication modules (Wireless M-Bus), it is ideally suited for integration with building automation systems and remote meter reading. The possibility of connecting additional devices with a pulse output (water meters, gas meters) increases the functionality of the measurement system.

Key features and benefits

• Versatility: Can operate as a heat, cooling, or both meter – the operating mode is defined upon order.
• Accuracy: Accuracy class 2 ensures reliable energy consumption measurements.
• Communication: Modbus protocol support enables easy integration with energy monitoring and management systems.
• Installation: Possibility of horizontal or vertical installation simplifies installation in various conditions.
• Durability: Brass body provides corrosion resistance and long-term operation.
• Energy saving: Battery power ensures independence from the electrical network.
• Dynamic measurement: Short temperature measurement period (2-6 s) makes the meter perfect for residential heat substations (logoterms).
• Protection: Protection class IP54 protects the device from dust and water splashes.
• Flexibility: The ability to exchange communication modules allows you to adapt the meter to changing system needs.

The ELF 2 heat meter is a reliable solution for installers and end-users looking for a precise and versatile device for measuring thermal and cooling energy consumption. Its solid construction, rich communication possibilities, and ease of installation make it an ideal choice for a variety of applications.
