The meter body comprises a water inlet flow pass, a first flow pass, a measuring flow pass, a second flow pass and a water outlet flow pass which are connected in sequence. A water level sensor for detecting the water level is arranged inside the water inlet flow pass so that the controller can determine the water flow. The first ultrasonic transducer and the second ultrasonic transducer are installed at the portions, at the two ends of the measuring flow pass, of the meter body through a first rotating disc and a second rotating disc respectively. The first rotating disc and the second rotating disc can rotate. The measuring flow pass is composed of a first measuring pipeline and a second measuring pipeline. The flow of the first measuring pipeline is smaller than that of the second measuring pipeline, and the first measuring pipeline is located below the second measuring pipeline. A first electric control valve is arranged in the first measuring pipeline. A second electric control valve is arranged in the second measuring pipeline. The first ultrasonic transducer, the second ultrasonic transducer, the first electric control valve and the second electric control valve are electrically connected with the controller. By the application of the intelligent ultrasonic water meter, the metering accuracy is high no matter whether the water flow is large or small.
