Ultrasonic STS AMR Water Meter measure water flow by detecting ultrasonic beam when the water velocity changing, analyzing ultrasonic beam to measure water velocity to draw a conclusion that the water discharge. It has high accuracy reach to R200, and would not measure air, not be effected by sand. It has Real-time clock (RTC), real-time volume calculation & monthly billing data etc. functions to provide real-time water consumption statistics. Meanwhile it has Friendly Period management function to ensure the water use in holidays and duty-off time Periods as human-based management of water supply.
