Ultrasonic water meter QALCOSONIC FI designed for measurement of cold and hot water consumption in households and blocks of flats, as well for industrial applications. • Static method of water flow measurement • High accuracy calculation of water consumption • Long-term measurement stability and reliability WIRED M-BUS INTERFACE (SPECIAL ORDER) The internal M-Bus module provides data reading posibility via M-Bus protocol. The optical interface is integrated into the front panel of the calculator. It is designed for data reading via M-Bus protocol and parametrization of the meter, reading of optical pulse values in the TEST mode. NFC interface is used for LoraWAN communication parameter reading. RADIO INTERFACE Integrated radio communication allows data reading via wM-Bus telegram: 433 MHz or 868 MHz, OMS S1, T1 mode, LoRa WAN. TECHNICAL FEATURES • No straight sections required • Temperature measurement possibility Pt 500, 0-180°C • Internal data logger • Battery lifetime > 16 years • Power supply options: Battery/External power supply • Optional communication modules • Measure reverse flow (to additional register) • Flow direction indication UNIVERSAL PULSE INPUTS/OUTPUTS (SPECIAL ORDER) • Pulse cable (optional) • Two configurable pulse outputs/inputs M-Bus JVtBus^ ^/lodbus

Power supply (one of the following depending on meter configuration): • 2 x AA battery 3,6 V 2,4 Ah (Li-SOCl2) battery, operation time at least 16 years. • 12..42 V DC or 12...36 V 50/60Hz AC external power supply, used current 10 mA and back up battery AA 3,6 V (Li-SOCl2) (Optional). Depending on the order, the meter can have up to 3 cables outputs (cable length 1.5 m). The cables can have from two to four core wires. The cable core is identified by the number and color of different communication module applications.
