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

Abstract

The invention provides an ultrasonic water meter, comprising a meter body, a first ultrasonic transducer, a second ultrasonic transducer and a controller, wherein the meter body comprises a water inlet passageway, a first passageway, a measuring passageway, a second passageway and a water outlet passageway which are connected in sequence and form a convex shape like a Chinese character tu, the first ultrasonic transducer and the second ultrasonic transducer are respectively on the water body at two ends of the measuring passageway, the measuring passageway consists of a first measuring pipeline and a second measuring pipeline, the flow rate of the first measuring pipeline is smaller than that of the second measuring pipeline, the first measuring pipeline is located below the second measuring pipeline, a first electronic control valve is arranged in the first measuring pipeline, a second electronic control valve is arranged in the second measuring pipeline, and the first ultrasonic transducer, the second ultrasonic transducer, the first electronic control valve and the second electronic control valve are all electrically connected with the controller. When the ultrasonic water meter is used, no matter water flow rate is great or small, the measuring accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to an 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 output signal ...
