Apator Elf Heat Meter


Apator Elf Heat Meter

The ELF heat meter is designed to take measurements of thermal energy consumption collected from heat networks out of small buildings, flats or detached houses. It can work in remote systems and take automatic readings.

A precise, reliable, high class heat meter that can archive a lot of measurement data, it is also characterized by a modern design.



  • flow rates 0,6; 1,0; 1,5; 2,3 m³/h available
  • flow transducer in second accuracy class according to standards PN-EN-1434
  • electronic detection of rotor rotation – total resistance to strong magnetic fields
  • wide communication possibilities, inter alia M-Bus, radio, impulse output, possibility of connecting 4 additional devices (4 additional impulse inputs)
  • plentiful archive of measurement data configured by the user
  • archive of failure situations


Heat meter functions

  • display of current data: heat consumption, water volume, temperatures of power and return, power, instantaneous flow, impulse inputs states (additional volumes of water meters), error codes, real-time
  • display of average data – averaging period set by the user with possibility of set-up every 15, 30, 45 and 60 minutes
  • data archive in 4 time cycles. In every cycle after the given time, the current data are transferred to the archive (from RAM of the processor to the non-volatile FLASH). Cycles 1 and 2 have a registration period set by the user counted in minutes starting from 1 to 1440 (24h). Cycles 3 and 4 are structurally defined as monthly and annual. Data from cycle registration 1 and 2 can be read only electronically, monthly and annual data can be read on the display
  • archive of failure situations – the appearance and disappearance of the failure situation (electronic reading)
  • display of configuration data (service), which can be set up in the non-metrological part by the user
  • self-diagnosis – detection and signaling of failure situations of the measurement system, e.g. failure of impulse from the water meter, damage of the temperature sensor, too high flow, battery voltage drop


Compatibility with standards and regulations

  • directive 2004/22/WE of The European Parliament and The Council of Europe dated on 2004, March 31 regarding measuring instruments, in particular MI-004 Heat Meters
  • PN-EN-1434 – Heat Meters, Part 1 – 6
  • PN-EN 61000 – electromagnetic compatibility, part 2-4

Designed in compliance with required standards of quality, of environmental protection and security.
