An ultrasonic open-channel flow meter generally consists of a flow display instrument, a flow velocity meter, and a level gauge； It can also be a open-channel flow system for multi-point flow measurement, consisting of one flow display instrument, up to four flow meters, and one level gauge. Suitable for flow measurement in rectangular and trapezoidal open channels as well as culverts, used in reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, farmland irrigation, and water resources management. There are many types of open-channel flow meters, with the commonly seen categories being weir-type open-channel flow meters and ultrasonic open-channel flow meters. This article mainly introduces the advanced features of ultrasonic open-channel flow meters. 1. Sewage foam has no impact on its measurement: This solves completely the problem posed by foam interfering with measurements. Due to the inherent properties of ultrasonic waves, it is difficult for them to penetrate through the foam in order to detect the actual water level, which prevents accurate measurement. 2. No debugging required; automatic zeroing ensures normal operation as soon as power is applied. The integrated design of the sensor and the measuring tank eliminates the need for complicated and professional debugging processes, providing great convenience for users. 3. The sensor is assembled using components imported from the United States, offering ultra-high sensitivity: it is a high-sensitivity sensor with a short measurement range, designed using integrated circuits from Motorola, enabling a measurement accuracy of 0.2%. 4. The measuring tank (weir plate) is manufactured by the manufacturer, resulting in greater accuracy compared to when it is built by the user themselves: imported open-channel flow meter manufacturers require customers to construct the measuring tank on their own; due to a lack of professionalism, this leads to significant errors, and it also causes inconvenience for the users. 5. The ultrasonic open-channel flow meter features a very strong signal, with a transmission distance of up to 2000 meters: After the sensor signal is processed and amplified, its transmission capability is **enhanced**, as is its resistance to interference, far exceeding the 20-meter limit of ordinary manufacturers. 6. Open-type gravity flow meters can measure flow in partially filled pipes: The manhole triangular weir open-channel flow meter is a flow meter specifically designed for use in underground manholes with partially filled pipes under the action of gravity. 7. Historical record query function, displaying daily, monthly, and annual reports: this facilitates environmental protection agencies in carrying out metering, settlement, as well as tracking and querying of records. 8. Power outage record query function, showing the time and frequency of outages: this facilitates users in calculating the unmeasured flow volume and preventing illegal discharge.
