Description

Technical Field

[0001] This utility model relates to the field of large-diameter water meter measurement, and more specifically to a structure for a large-diameter ultrasonic water meter. Background Technology

[0002] Currently, most large-diameter water meters are mechanical water meters. The measuring components of mechanical water meters are mostly impeller structures, which have high requirements for water quality and are prone to wear on the impeller shaft. Changes in the external environment have a significant impact on the measurement, resulting in a high failure rate and short service life. Therefore, traditional methods are inherently difficult for process measurement and have many problems such as measurement errors and correction factors, making it difficult to achieve high-precision measurements. It is not difficult to see that current large-diameter water meters have disadvantages such as low accuracy and precision of flow measurement results and inconvenience and inflexibility in pipeline construction and installation.

[0003] Large-diameter ultrasonic water meters employ advanced ultrasonic flow measurement technology. They utilize the time difference in the propagation of ultrasonic signals in upstream and downstream water to measure the water flow velocity and integrate the flow rate through the pipe. Furthermore, ultrasonic water meters have no moving parts or flow obstructions, eliminating pressure loss, resulting in low flow velocity and a wide measurement range. This eliminates many of the negative problems associated with traditional water meters, making them widely used in urban and rural water supply, farmland and garden irrigation, and industrial water applications.
