LoRaWAN Ultrasonic Water Meter DN15

Advanced Transit-Time Ultrasonic Flow Measurement

This DN15 Wireless Ultrasonic Water Meter represents the cutting edge in modern smart fluid measurement technology. Utilizing dual acoustic sensors, the meter measures the precise time difference of ultrasonic sound waves propagating upstream and downstream through the water medium. This transit-time differential method allows the integrated electronic calculator to accurately quantify real-time flow rate, flow velocity, and total volume consumption. Because the internal flow profile is entirely clear, the unit introduces virtually zero pressure drop and completely eliminates mechanical wear and clogging risks associated with traditional turbine or displacement meters.

Multi-Protocol Wireless and Wired Connectivity

Designed for seamless integration into Smart City infrastructure, Automatic Meter Reading (AMR), and Advanced Metering Infrastructure (AMI) networks, this smart meter supports versatile telemetry options. Equipped with modular transceiver hardware, it natively supports long-range LoRaWAN, NB-IoT, and 4G Cat1 wireless protocols for direct transmission to private or public cloud platforms. For wired utility installations or local building automation systems, RS-485 Modbus and M-Bus interfaces are provided, alongside an infrared optical maintenance port for effortless local field configuration and data retrieval.

High Precision and Exceptional Turndown Ratio

Engineered for high accuracy across dynamic consumption patterns, the meter features an ultra-low starting flow rate down to 0.004 cubic meters per hour. With achievable turndown ratios of R250 to R400, it reliably captures minor leaks, low-flow residential usage, and high-volume burst consumption with identical precision. The solid forged brass body and robust internal transducers resist magnetic tampering, hydraulic shock, and abrasive particulate wear from sand or rust fragments commonly found in municipal lines.

Industrial Reliability and Submersible IP68 Housing

Built to endure harsh pit environments, outdoor exposure, and prolonged immersion, the electronics enclosure achieves a true IP68 ingress protection rating. Power management circuitry is optimized for extreme low power consumption, allowing the onboard high-energy lithium battery to operate continuously for over 8 years without maintenance. Integrated diagnostics continuously monitor system status, automatically raising alarms for low battery capacity, pipe leakage, reverse flow, sensor fault, or electronic valve failure.

Onboard Intelligence and Local Data Storage

The integrated digital controller incorporates non-volatile memory to log historical billing data, daily volumetric accumulations, and alarm events directly on the device. An integrated high-contrast LCD screen provides immediate field visibility for parameters including cumulative volume in cubic meters or liters, instantaneous flow rate, fluid flow direction indicators, diagnostic warning codes, and current battery health. This dual local display and remote telemetry feature makes it an ideal instrument for municipal water utilities, commercial sub-metering, industrial process monitoring, and automated agricultural irrigation management.
