A New Chapter in Luzhou River Monitoring: Unveiling the Mysteries of Dayu Ultrasonic Doppler Flowmeters

　　1. Time: November 18, 2023

　　2. Location: Longmatan District, Luzhou City, Sichuan Province

　　3. Product Used: Ultrasonic Doppler Flowmeter

　　Project Overview: This project is a tributary river (flow) monitoring project in the Tuojiang River basin of Luzhou City. To protect the ecological balance of the river, relevant authorities decided to implement real-time monitoring of water level, flow rate, and cumulative flow for water entering the Tuojiang River from multiple tributaries in Longmatan District, Luzhou City.

　　Product Selection: Based on on-site inspections and the owner's requirements, the ultrasonic Doppler flowmeter manufactured by Fuzhou Dayu Electronic Technology Co., Ltd. was selected for this project to collect real-time water level, instantaneous flow, and cumulative flow data at the site. The owner's selected RTU transmits the data via RS485 to the owner's designated platform for convenient data viewing and effective management.

　　Power Supply (Solar Power System): 12-24V, 65AH battery, 80W solar LCD panel, solar smart controller, 3-meter pole, ground anchor cage, waterproof enclosure;

　　1. Velocity measurement range: 0.03 m/s to 5.00 m/s;

　　2. Velocity measurement resolution: 1 mm/s;

　　3. Velocity measurement accuracy: ±1% of measured velocity;

　　4. Water depth measurement: 0.02 m to 10.00 m; Resolution: 2 mm; Accuracy: ±0.2%;

　　5. Temperature range: 0 to 60°C; Resolution: 0.1°C;

　　6. Flow range: 10 L/s to 99,999,999 m³/h;

　　7. Power supply: 12 VDC;

　　8. Output signal: RS485; RS485 output data includes: velocity, instantaneous flow, cumulative flow, water level, and temperature.
