Real Realneeds. solutions. Application QALCOSONIC E3 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 • Brass flow measuring part LSRaUftN' M-Bus ■^BACnet' JVtBus. • Flexible meter configuration. Meter is delivered in user configuration mode with possibility to configure meter parameters and features as: units, mounting position, pulse inputs/outputs, communication ON / OFF and other meter parameters • Dual communication module options (Integrated: M-Bus (standard), M-Bus/wM-Bus. Optional: Modbus RTU, BACnet MS/TP, LoRaWAN) • Measuring accuracy class 2 • Dynamic range up to qp/qi = R 100/250 • No straight sections required U0D0 for DN15 - DN50, U5D3 DN65-DN80 • Pressure loss class P25/63 • Calculator unit measurement range: 0 0C ... 180 0C • Temperature of conveying liquid: 0,1 0C ... 130 0C • Metering archive • Battery lifetime > 15+1 years • Power supply options: battery/external • Optional communication modules • Mounting in any installation position • Tariff functions * - Non modular design only

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 T1 OMS mode or LoRaWAN. • Integrated heat energy • Integrated cooling energy • Integrated energy of tariff • Integrated volume of liquid • Integrated pulse value in pulse input 1/2 • Maximum thermal power value for heating / cooling • Maximum and maximum value of flow / return temperature of heat conveying liquid and date • Average value of flow/return temperature of the heat conveying liquid • Minimum...

• 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 /pulse • If the meter is ordered with...
