Water meters

Smart and prepaid water meters with remote reading.

Quill’s water meter range covers LoRaWAN prepaid smart water meters (QE-WL-XX) and ultrasonic smart water meters (QE-WS-XX, DN 15 to DN 50). Both are MID certified and IP68 rated for residential compounds, commercial buildings and municipal water networks.

Remote reading, leak detection and tamper alerts help operators cut non-revenue water, while the optional prepaid IC card and control valve let them collect in advance and manage supply remotely through QE-SYS-2.0.
