Compact residential heat meter, type ELF 2, DN15 (1/2"), Q3=1.0 m3/h, Tmax: 90°C, L=110mm, return line installation, GZ3/4" connection, brass body 69-0046207-000

Compact heat meter for precise energy measurement

This compact heat meter, type ELF 2, is an advanced device designed to measure heat or cooling consumption in heating and cooling systems. It is ideal for use in residential, office, and commercial buildings. Thanks to its precise measurement and remote data reading capabilities, it allows for cost optimization and efficient energy management. Installation on the return line ensures stable readings, and the brass body guarantees durability and corrosion resistance.

Construction and functionality

The ELF 2 heat meter uses a single-jet mechanical flow converter, providing measurement accuracy in accordance with PN-EN 1434 (class 2). The device is battery-powered, ensuring independence from external energy sources. It has a built-in PT500 temperature sensor that accurately measures the temperature of the medium flowing through the installation. Support for the Modbus protocol enables integration with building automation systems and remote data reading. The ability to operate as a heat, cooling, or both parameters meter in one installation increases its versatility.

Advantages and application

• Versatility: Can operate as a heat, cooling, or both meter simultaneously – configuration selected upon order.

• Accuracy: Class 2 accuracy ensures precise energy consumption measurements.

• Communication: Modbus protocol support enables integration with remote reading and building automation systems.

• Durability: The brass body provides corrosion resistance and long device life.

• Installation: Can be mounted in both horizontal and vertical positions, making installation easier in various conditions.

• Dynamic measurement: Short temperature measurement period (2-6 s) is ideal for residential heating units (logoterms).

• Battery power supply: Ensures independence from external energy sources.

• Protection: IP54 protection rating protects against dust and water splashes.

The ELF 2 heat meter is used in:

• Residential buildings

• Office buildings

• Commercial buildings

• Apartments

• Residential heating units (logoterms)

The device is particularly recommended for applications where high measurement accuracy and remote data reading are required. Thanks to its compact design and aesthetic appearance, it fits perfectly into any interior.
