HWU Series Small-diameter IoT Ultrasonic Water Meter

Product Overview

The HWU Series Small-Diameter IoT Ultrasonic Water Meter utilizes the transit-time difference of ultrasonic pulses propagating downstream and upstream in a liquid to measure flow velocity. It then calculates the flow rate within the pipe, with temperature compensation based on collected data for enhanced measurement accuracy. The meter body contains no mechanical moving parts, resulting in zero wear and tear, a long service life, and low maintenance costs. It supports various communication protocols, enabling remote meter reading and facilitating efficient centralized management.

Product Advantages and Features

1. High-Precision Picosecond Measurement: Equipped with a picosecond-level measurement chip, the device features an ultra-low starting flow rate and a wide measuring range. Its high accuracy allows for the precise detection of even dripping water.

2. Fully Encapsulated Electronic Design: The electronics are entirely sealed, providing comprehensive protection against water, moisture, dust, contaminants, and sand.

3. Robust Data Storage: Capable of storing 24 monthly records, 360 daily records, and 192 hourly records. All data is non-volatile and will not be lost during power outages.

4. Real-time Monitoring & Intelligent Alerts: Provides real-time monitoring of battery status, temperature, and flow rate. It includes intelligent diagnostics to record and alert for low voltage, transducer abnormalities, or empty pipes, with warnings displayed directly on the screen.

5. Diverse Communication Protocols: Supports multiple communication interfaces, including RS485, M-Bus, NB-IoT, LoRa, 4G, and TTL, for centralized meter reading and remote parameter configuration.

6. Remote OTA Upgrades: Supports online remote firmware upgrades to meet evolving requirements and provide long-term peace of mind for users.
