APPLICATION

Ultrasonic water meter QALCOSONIC W1 is designed to accurately measure cold and hot water consumption in households, apartment buildings, and small commercial premises.

It is Europe's first ultrasonic water meter with integrated Narrow-Band-IoT (NB-IoT) technology.

• Static method of water flow measurement, no moving parts
• Very high metering accuracy
• Eliminates measuring deviations caused by sand, suspended particles, or air pockets
• Long-term measurement stability and reliability 
• 9 digits, multi-line LCD. Total volume and instantaneous flow rate indication
• Sensitive and accurate in low flows, down to 3 l/h
• Integrated NB IoT or LoRa WAN technology - ready for AMR
  

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)
