Ultrasonic Water Metering Module
The WM1000-S1 ultrasonic water meter module is a high-precision metering solution developed by Santrua Tech for residential ultrasonic water meters.
Designed for integration with DN15, DN20, and DN25 pipe sizes, this compact ultrasonic water meter module measures water flow based on the transit-time difference of ultrasonic signals in the forward and reverse directions, offering reliable and maintenance-free operation.
Key Features
- All-in-One DesignCombines flow sensing, temperature measurement, error correction, and status monitoring into one integrated module.
- Smart Communication InterfaceCommunicates with the main control board via UART, periodically transmitting real-time flow rate, volume, and operational status. The module pushes data passively—no need for the MCU to participate in measurement logic.
- Easy to IntegrateEnables water meter manufacturers to develop smart ultrasonic water meters with a development process similar to that of mechanical meters.
- Low Power and High AccuracyDesigned for battery-operated water meters with low power consumption and high metering precision.
This ultrasonic water meter module is ideal for OEMs seeking to upgrade mechanical designs to smart, IoT-enabled water metering systems without complex engineering.
