APPLICATION 

Ultrasonic water meter QALCOSONIC W1* is designed for accurate

measurement of cold and hot water consumption in households,

apartment buildings, and commercial premises.

• Static method of water flow measurement, no moving parts

• High accuracy calculation of water consumption

• 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 1 l/h

• Ready for AMR with NFC, wM-Bus, LoRa technologies

* - Qalcosonic W1 modification for Belgium, Netherlands, France, Germany,

Denmark, Norway, Finland, Poland.

AMR READY 

• wM-Bus 868 MHz OMS T1

• LoRaWAN (EU863-870)

• NFC
