Ultrasonic Water Meters: The Smart Solution for Modern Water Management
1. Working Principle
Water flows through the metering tube equipped with paired ultrasonic transducers. The transducers emit 1MHz ultrasonic signals both with and against the flow direction. The microprocessor calculates the time differential (Δt) between upstream and downstream signal propagation. Flow velocity is derived from the formula:(Where L = acoustic path length, K = calibration constant)Total volume is then calculated by integrating velocity with cross-sectional area. Valve control is executed via encrypted wireless commands (NB-IoT/LoRaWAN) or local infrared signals.

How Ultrasonic Water Meters Work
Unlike traditional mechanical meters, ultrasonic water meters utilize transit-time difference technology to measure flow. Two ultrasonic sensors transmit sound waves diagonally across the pipe:
Downstream wave: Travels faster with the flow
Upstream wave: Slows against the flow
By calculating the time difference between these waves, the meter determines flow velocity with ±1% accuracy, even in turbulent conditions.
