Problems solved by technology
The ultrasonic propagation direction of the beam ultrasonic water meter crosses the water flow direction at a certain angle, the output signal is small, the structure is complex, and the cost is high
The reflective ultrasonic water meter will weaken the ultrasonic energy by reflecting the ultrasonic wave through the reflective sheet, and the reflective element is susceptible to the deposition of scale to weaken the ultrasonic energy, and the ultrasonic water meter uses a single channel for measurement. The smaller the water flow, the lower the measurement accuracy

The invention provides an intelligent ultrasonic water meter which comprises a meter body, a first ultrasonic transducer, a second ultrasonic transducer and a controller. 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.
Description
technical field [0001] The invention relates to the technical field of water meters, in particular to an intelligent ultrasonic water meter. Background technique [0002] As everyone knows, in order to save water sources and control artificial waste of water resources, water meters are usually installed on the water inlet pipes of each household. Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic sound beam propagates in the water upstream and downstream, analyzes and processes the flow velocity of the water, and then further integrates the flow of the water. High precision and stable work are popular. [0003] Existing ultrasonic water meters are divided into direct beam type and reflective type according to the layout of sound channels. The ultrasonic propagation direction of the through-beam ultrasonic water meter intersects with the water flow direction at a certain angle, and the ou...
