QALCOSONIC W2 – ULTRASONIC WATER METER WITH AN INTEGRATED SMART VALVE
APPLICATION
QALCOSONIC W2 accurately measures water consumption and enables remote water supply management through its integrated valve. It helps utilities secure timely payments and manage water infrastructure more efficiently, while giving users greater visibility into their water use.
- Static method of water flow measurement, no moving parts
- High accuracy of water consumption measurement
- Eliminates measuring deviations caused by sand, suspended particles or air pockets
- Long-term measurement stability and reliability
- 10-digit, multi-line LCD. Total volume and instantaneous flow rate indication
- Sensitive and accurate at low flows, down to 1 l/h
- Failsafe mechanisms in place for every real-life scenario
- Configurable physical button on the housing
- Daily consumption mode enables setting a daily usage limit in litres
- Valve health monitoring
- Configurable partial valve position
- Equipped with NFC, wM-Bus, LoRa and NB-IoT technologies
AMR READY
- wM-Bus 433 or 868 MHz OMS T1
- LoRaWAN (EU863-870, AS923, AU915-928, US902-928, IN865-867 channel plans)
- NB-IoT (CoAP, DLMS)
- NFC
PARAMETERISATION
- NFC and optical interfaces on the top panel enable meter data reading and parameterisation
- Valve and meter parameterisation is available over the air (COTA)
