In the fields of modern hydrology, hydraulic engineering and environmental protection, the accurate monitoring of velocity and discharge is very important. The Doppler current meter, as the right-hand man in this field, plays an irreplaceable role in the flow rate monitoring of rivers, open channels and pipelines with its significant advantages of non-contact measurement, high precision and strong real-time performance.
The working principle of the WX-LS6 Doppler current meter is based on the Doppler effect, that is, when there is relative motion between the transmitting source and the receiver, the frequency received by the receiver will be different from the frequency emitted by the transmitting source. In velocity measurement, a Doppler current meter uses the relationship between frequency difference and velocity to calculate water velocity by transmitting ultrasonic signals and receiving the reflected signals. At the same time, it can also determine the liquid level by measuring the time difference between ultrasonic transmission and reception, so as to achieve a comprehensive monitoring of water flow.
In river monitoring, Doppler current meter has shown its excellent performance. Whether it is a calm stream or a fast-flowing river, the Doppler current meter provides reliable measurement data. It can monitor the speed of water flow in the river in real time and provide scientific basis for river management. Before the flood, by monitoring the abnormal increase in the flow rate, the Doppler current meter can warn in advance, and help the management department to take timely measures to deal with the flood disaster, so as to effectively protect the safety of people's lives and property. At the same time, it can also provide better decision support for water resources management departments, through the analysis of flow rate data, reasonable adjustment of reservoir storage and release plans, to achieve optimal allocation and utilization of water resources.
The Doppler current meter also performs well in the measurement of open channel velocity. It can accurately measure the speed of water flow in open channels, helping farmers optimize irrigation strategies, reduce water waste, and ensure that crops receive adequate and appropriate water supply. This is of great significance for promoting the sustainable development of agriculture. In addition, the Doppler current meter can also be applied to the flow rate measurement of municipal sewer pipes, providing data support for pipeline maintenance, dredging and reconstruction, effectively preventing the occurrence of blockage, overflow and other problems, and ensuring the smooth operation of urban drainage system.
