Ultrasonic open channel FLOW METERs are commonly used devices for measuring flow at discharge points, intake points, and channels. They typically emit 100kHz and 64kHz ultrasonic signals for measurement. The device uses Parshall flumes, triangular weirs, and rectangular weirs as supporting structures. Its core working principle utilizes the time difference of ultrasonic wave transmission to accurately measure the head height upstream of the throttling device. The flow rate is then calculated using a preset formula or by looking up a table, and finally, the measured flow value is directly displayed.

It boasts numerous practical advantages. Power supply options are flexible and diverse. In addition to 220V AC power, it can also be used with a 12V solar power system. For field installations, the solar power system provides a convenient power source, facilitating decentralized deployment and adapting to the power needs of different installation scenarios. The main unit supports remote setting, allowing for easy parameter adjustments via remote operation, effectively reducing installation and maintenance costs. Furthermore, the device is cost-effective, highly reliable, unaffected by water impurities and entanglements, and requires relatively little daily maintenance. Furthermore, the device's main unit can upload timestamped measurement results to a server via a built-in 4G wireless transmission module, facilitating data traceability and enabling remote monitoring of flow data. This provides crucial data references for decision-making by relevant management departments and units. With these features, this flow meter can also provide important technical support in digital and smart twin projects related to urban water supply and drainage, environmental protection, and water conservancy.
