Real Real needs. solutions. Smart ultrasonic heat and cooling meter QALCOSONIC E4 is a cost-effective smart ultrasonic heating and cooling meter designed for commercial metering of consumed energy where water is the heat carrier, such as residential buildings, enterprises, commercial premises, or heat supply facilities. • Static flow metering using ultrasonic technology • High accuracy • Modular design with replaceable battery • MID DN15 - DN32* with the composite body flow part LoRaMaN' M-Bus ■ffBACnet' JVtBus, Special features • Flexible meter configuration. Meter is delivered in a user configuration mode with the possibility to configure the meter parameters and features as units, mounting position, pulse inputs/outputs, communication ON / OFF, and other meter parameters • Dual communication module options • (RF/M-Bus, M-Bus/ M-Bus, LoRa/M-Bus) • Measuring accuracy class 2 • Dynamic range up to qp/qi = R 100/250 • No straight sections required • Temperature measurement sensor type Pt500, from 0 0C to 90 0C • Temperature of conveying liquid: from 0,1 0C to 90 0C • Composite flow part • Metering archive • Battery lifetime > 15+1 years • Power supply options: battery/external • Optional communication modules • Mounting in any installation position • RF and M-Bus on-board (by request) • Tariff functions

Integrated into the front panel of the calculator. It is designed for data reading via M-Bus protocol and parameterisation of the meter. The internal radio provides data reading via wM-bus telegram: S1, T1 OMS mode, LoRa. Every hour, day, and month value of the measured parameters are stored in internal memory. • All data from the archive can be read using the remote reading • In addition, data logger records of monthly parameters can be seen on the display • Hours for archive records: 1480 h • Days for archive records: 1130 days • Months for archive records: 36 months • Archive data storage...

Pulse value in the operating mode: • When the output is configured for energy, the value of its pulses can be selected from the list (depending on the rated flow qp and energy measurement units): Energy pulse value, when units are "kWh" or "MWh" 0,00001 - 10 000 MWh/pulse Energy pulse value, when units are "GJ" 0,0001 - 10 000 GJ/pulse Energy pulse value, when units are "Gcal" 0,0001 - 1 000 Gcal/pulse • When the output is configured for water quantity, the value of its pulses can be selected from the list (depending on the permanent flow qp): Water volume pulse value, m3 /pulse 0,001 - 10 m3...
