Product Overview
The Ultrasonic Meter DN15–DN40 for Smart Water Metering with Remote Reading is designed for accurate water consumption measurement in residential, commercial, and municipal smart water networks. It uses the ultrasonic transit-time principle to measure flow by detecting the time difference between upstream and downstream ultrasonic signals.
With NB-IoT, CAT.1, RS485, and M-BUS communication options, the meter supports remote reading, automatic data reporting, abnormal usage monitoring, and integration with smart water management platforms. Its straight-through flow channel has no mechanical moving parts in the measuring section, helping reduce wear, pressure loss, and maintenance requirements.
Key Features
- Ultrasonic transit-time measurement: Measures flow by comparing the travel time of ultrasonic signals in forward and reverse flow directions.
- Smart remote reading: Supports NB-IoT, CAT.1, RS485, and M-BUS communication for remote metering and data collection.
- Wide size range: Available in DN15, DN20, DN25, DN32, and DN40 for different pipe installations.
- High accuracy and stability: Accuracy class 2 with support for bidirectional flow measurement.
- Low power consumption: Static current ≤30 μA and battery life over 6 years.
- IP68 protection: Designed for demanding metering environments with moisture, dust, and water exposure.
- Straight-through flow channel: No impeller structure, reducing the risk of blockage or jamming.
- Flexible installation: Supports horizontal or vertical installation.
- Abnormal event detection: Optional alarms for pipeline leakage, pipe burst, scaling, battery abnormality, and water usage abnormality.
- Historical data storage: Supports storage of daily/monthly flow data, instantaneous flow, water temperature warning, pressure fluctuation, and related usage records.
Applications
- Residential smart water metering
- Apartment and community water management
- Commercial building water metering
- Municipal water supply networks
- Remote water billing and monitoring systems
- Leakage monitoring and abnormal water usage detection
