Elf 2 (DN15-20)
- High measurement accuracy, 1:100 measurement dynamics, metrological stability ensures correct and accurate billing of energy consumption
- Operation in heat, cooling, or heat and cooling systems
- Dynamic temperature measurement and integration period (2-6 sec) ensures correct energy measurement even under short flows – perfect for residential heat distribution units
- The interchangeable communication modules ensure operation in reading and building automation systems, and allow the connection of four different meters with pulse output to Elf 2 (water meters, electricity meters)
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.
- Small dimensions, horizontal or vertical mounting and rotating display, which allows installation and readability in any environment
- High measurement accuracy, 1:100 measurement dynamics, metrological stability ensures correct and accurate billing of energy consumption
- Operation in heat, cooling, or heat and cooling systems
- Versions with different nominal flow rates (0.6, 1.0, 1.5, 2.5 m3/h) and diameters (DN15, DN20) ensures optimum selection for metering any room
- Dynamic temperature measurement and integration period (2-6 sec) ensures correct energy measurement even under short flows – perfect for residential heat distribution units
- Battery power for up to 6 or up to 12 years of operation
- The interchangeable communication modules ensure operation in reading and building automation systems, and allow the connection of four different meters with pulse output to Elf 2 (water meters, electricity meters)
- Extensive archiving capability for measurement data in retentive memory: registers per minute (15-1440 minutes), hour, day, month and year ensures safe measurement data storage and possibility for the complete analysis of meter operation
- Archive register reading and customisation of meter configuration for individual needs with dedicated software
Interchangeable communication modules
- M-Bus + 4 pulse inputs
- M-Bus + 2 pulse inputs + 1 pulse output
- RS485 with Modbus protocol
- RF Wireless M-Bus T1 + 2 pulse inputs
- USB – service
Elf 2 Service program for configuring Elf and Elf 2 heat meters, in particular:
- setting the measurement unit
- address settings in Mbus and ModBus communication
- settings of pulse inputs/outputs (pulse value, initial state, etc.)
- insensitivity of DT measurement - energy is counted from the temperature difference (in the range of 0.1oC to 3oC)
- event threshold settings
- archive settings
IMPORTANT: the Elf 2 Serwis program requires the creation of an account to work in the program.
The program is not used for reading archive data.
The program requires a USB-service connector
