Product Overview
The Ultrasonic Meter DN15 for Drinking Water Metering with NB-IoT / CAT.1 is designed for drinking water and direct drinking water metering applications. It uses the ultrasonic transit-time principle to measure flow by detecting the time difference between ultrasonic signals traveling with and against the water flow.
With NB-IoT and CAT.1 communication, the meter supports remote reading, automatic data reporting, and integration with smart water management platforms. Its ultrasonic measuring structure has no mechanical moving parts in the flow channel, helping improve measurement stability and reduce long-term maintenance requirements.
Key Features
- Designed for drinking water metering: Suitable for direct drinking water systems and clean water metering applications.
- Ultrasonic transit-time measurement: Measures water flow based on the time difference between upstream and downstream ultrasonic signals.
- NB-IoT / CAT.1 communication: Supports remote reading and data transmission for smart water management systems.
- High measurement accuracy: Accuracy class 1 for drinking water metering applications.
- Low power consumption: Static working current ≤20 μA and battery life over 6 years.
- IP68 protection: Suitable for humid or demanding installation environments.
- Bidirectional flow measurement: Reverse flow can be measured for improved monitoring and system diagnostics.
- Flexible installation: Supports horizontal or vertical installation.
- Optional abnormal event alarms: Supports pipeline leakage, pipe burst, and scaling detection alarms.
- Historical data storage: Supports storage of water usage records, instantaneous flow data, warnings, and operating status information.
