In today's society, with the progress of science and technology and the increasing awareness of environmental protection, the importance of hydrological monitoring is becoming more and more prominent. As the right hand of modern hydrologic monitoring, Doppler flow meter is becoming a new tool to protect the safety of rivers and lakes with its unique advantages and wide application scenarios.

WX-LS6 Doppler flow meter is a non-contact flow meter based on Doppler effect. It uses the interaction between sound waves and scatterers in the water flow (such as suspended particles, bubbles, etc.) to measure the change in the frequency of sound waves and then calculate the velocity and discharge of water flow. This measurement method not only avoids the mechanical wear and pollution problems that may exist in traditional contact measurement, but also enables accurate measurement in complex water flow environments.

The application of Doppler flow meter in hydrological monitoring is extensive and deep. In river monitoring, it can monitor key parameters such as river level, velocity and discharge in real time, providing important data support for flood control and disaster reduction, water resources management and water ecological protection. In lake monitoring, the Doppler flow meter can accurately evaluate the water quality and ecological health of the lake, and provide scientific basis for lake protection and management. In addition, the Doppler flow meter also plays an indispensable role in the fields of Marine environment monitoring, water conservancy project operation management and urban drainage system monitoring.

The advantage of Doppler flow meter lies in its characteristics of high measurement accuracy, fast response speed and wide application range. Compared with traditional measurement methods, it can better adapt to the complex and changeable water flow environment to ensure the accuracy and reliability of measurement data. At the same time, the Doppler flow meter also has the advantages of simple installation and easy maintenance, which can greatly reduce the difficulty and cost of hydrological monitoring.
