Flow rates 0,6; 1,0; 1,5; 2,5 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, interalia 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
ELF heat meter is designed for measurements of thermal energy consumption collected from heat networks out of small buildings, as flats or detached houses, etc. It can work in remote systems of building automation readings.
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 signalling 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
