Product overview
The DN15 ultrasonic drinking water meter with NB-IoT / CAT.1 is engineered for direct drinking water and clean water metering. It uses the ultrasonic transit-time principle to determine flow by measuring the time difference between upstream and downstream ultrasonic signals. The non-mechanical measuring path improves long-term stability and reduces maintenance needs.

Key features

• Designed for drinking water metering: Suitable for direct potable water systems and clean-water applications.
• Ultrasonic transit-time measurement: High-resolution flow measurement without moving parts in the flow channel.
• NB-IoT / CAT.1 communication: Remote reading, automatic reporting and integration with smart water management platforms.
• High accuracy: Accuracy class 1 for drinking water metering.
• Low power consumption: Static working current ≤20 μA; battery life >6 years.
• Durable protection rating: IP68 suitable for humid or demanding installations.
• Bidirectional measurement: Reverse flow detection for improved monitoring and diagnostics.
• Flexible installation: Supports horizontal or vertical mounting.
• Optional alarms: Pipeline leakage, burst pipe and scaling detection available.
• Data logging: Historical records of consumption, instantaneous flow, warnings and operating status.

Applications

• Direct drinking water metering
• Residential potable water systems
• Commercial drinking water supply
• Apartment and building water metering
• Smart water management platforms
• Remote billing and monitoring systems
