An ultrasonic water meter with NB-IoT or Lorawan connectivity is a smart device that uses sound waves to measure water flow and transmits the data remotely via a cellular Narrowband-Internet of Things (NB-IoT) network. This combination enables high accuracy, automated data collection, and efficient water management for both users and utility providers

Key Features and Benefits

• No Moving Parts: Unlike traditional mechanical meters, ultrasonic meters have no internal moving parts subject to wear and tear, ensuring consistent, high accuracy throughout their entire operational life and minimal maintenance requirements.
• High Accuracy: They provide precise readings, even at very low flow rates (as low as 1 liter per hour), which helps in detecting even the smallest consumption or leaks and reduces non-revenue water loss.
• Remote Reading: The integrated NB-IoT module (which uses a SIM card) sends data directly to a cloud server or management platform over a wide-coverage, low-power cellular network, eliminating the need for manual readings and significantly reducing operational costs.
• Anomaly Detection: The smart meters are equipped with intelligent alerts that can detect a variety of issues in real-time, including:
  • Leaks and pipe bursts
  • Reverse flow
  • Tampering or meter damage
  • Low battery capacity
• Long Battery Life: NB-IoT technology is designed for ultra-low power consumption, allowing these meters to operate on a single battery for up to 4-5 years, depending on usage conditions.
• Durable and Robust: With an IP68 protection rating, many of these meters are designed to be completely waterproof and can work submerged for long periods, suitable for various environmental conditions.
• Bi-directional Flow Measurement: Many models can measure and store both forward and reverse flow data.
