Product Overview
The Ultrasonic Meter is a smart water metering device designed for residential, commercial, and utility water management applications. It measures flow based on the transit-time difference of ultrasonic signals traveling with and against the water flow, enabling accurate measurement without mechanical moving parts in the flow channel.
With integrated remote valve control and multiple communication options including NB-IoT, CAT.1, RS485, and M-BUS, this meter supports remote reading, data reporting, abnormal usage monitoring, and remote shutoff management. It is suitable for smart water networks, prepaid water management, leakage control, and IoT-based utility metering systems.
Key Features
- Ultrasonic transit-time measurement: Measures water flow by detecting the time difference between upstream and downstream ultrasonic signals.
- Remote valve control: Supports remote valve opening and closing for water supply management, emergency shutoff, and account control.
- NB-IoT / CAT.1 communication: Provides stable wide-area wireless connectivity for smart water metering networks.
- Multiple interface options: Supports NB-IoT, CAT.1, RS485, and M-BUS communication for flexible system integration.
- High measurement accuracy: Accuracy class 2 with bidirectional flow measurement capability.
- Ultra-low power design: Static current ≤30 μA and battery life over 6 years.
- IP68 protection: Suitable for demanding installation environments with high moisture or possible water exposure.
- No flow-blocking structure: Straight-through flow channel helps reduce pressure loss and eliminates the risk of impeller jamming.
- Abnormal event detection: Optional alarms for pipeline leakage, pipe burst, and scaling detection.
- Data storage capability: Supports storage of historical water usage data such as daily/monthly volume, instantaneous flow, temperature warnings, and pressure fluctuation records.
Applications
- Smart residential water metering
- Apartment and community water management
- Remote water billing systems
- Prepaid water metering systems
- Leakage monitoring and abnormal water usage detection
- Municipal smart water networks
