ELF 2

The latest-generation complete heat and cooling meter with a JS90-TI propeller flow sensor (DN15-20)


The meter can work in heating and cooling systems operated in residential, office, and utility buildings, as well as individual apartments. The stylish design helps with seamless installation in any interior setting. The meter can measure heat or cold, or both heat and cold, within the same system. For installation in horizontal piping with the counter sideways (H) or in vertical piping (V). The dynamic temperature measurement period and integration (2 to 6 s) makes the meter perfect for application in apartment-wide space heating and DHW subconnections (“Logothermas”). The extensive connectivity options enable operation in wired or wireless AMR systems and BMS (building automation systems).

Compact heat and cooling meter(DN15-20)

  • Adapted to the remote readings


  • Resistance to strong magnetic fields


  • Minimum service life - 12 years


  • Application

    The meter is designed for heating/cooling systems in residential, office, commercial and apartment buildings. Due to its attractive design, the meter fits into any room. It can be used as a heat meter, cooling meter, or heat and cooling meter in one system. It can be mounted horizontally or vertically. It is perfect for residential heat distribution units (logoterma) thanks to dynamic temperature measurement and integration time (2-6 s). Thanks to wide communication capabilities, the meter can be used in cable and wireless automatic reading systems as well as in building automation systems.
