Find out what the ELF heat meter has to offer
The ELF is a modern, multifunctional compact heat meter based on a microprocessor-controlled heat meter with a Class 2 turbine flow transducer. The device is designed for the precise measurement of heat consumption in small residential and office buildings. Thanks to electronic reading of the impeller’s revolutions and extensive archiving of measurement data, it ensures reliable and stable measurement results. It features a modern design, independent battery power supply and high resistance to external interference. The heat meter is designed for use in systems with a heating medium temperature of up to 90°C (105°C*) and a maximum operating pressure of 16 bar (PN16), and can be installed in both horizontal and vertical pipes.

By using the ELF heat meter, you benefit from:
high measurement accuracy in measuring thermal energy thanks to accuracy class 2 (H) and class 3 (V)
no need for mains power supply thanks to battery power supply
long battery lifetime – up to 10 years + 1 in a special version
immunity to interference thanks to complete resistance to strong external magnetic fields
stability of readings thanks to the flat error characteristic of the flow transducers
can be installed in a variety of installation configurations thanks to horizontal (H) or vertical (V) installation
easy installation thanks to the sensors’ 2-metre connection cables
extensive communication options thanks to replaceable communication modules, including M-Bus, Wireless M-Bus, and USB pulse and service modules
