As an advanced water level measurement device, radar water level meter plays an increasingly important role in the field of canal irrigation.
This article will discuss the working principle, characteristics and application of radar water level meter in canal irrigation water level measurement.
Radar water level meter is a device that uses microwave technology to measure water level. It transmits microwave signals, which are reflected when they encounter the water surface, and then the receiver receives the reflected signal.
The water level can be calculated based on the time difference between the transmitted and received signals.
Radar water level meter has the characteristics of non-contact measurement, high precision, and high stability, so it has been widely used in canal irrigation water level measurement.
Application of radar water level meter in canal irrigation water level measurement:
1. Real-time monitoring: radar water level meter can monitor the change of canal water level in real time, provide accurate water level data for irrigation management departments, help to reasonably allocate water resources and improve irrigation efficiency.
2. Early warning function: radar water level meter can set water level early warning value. When the water level exceeds the early warning value, the system will automatically issue an alarm to remind relevant personnel to take corresponding measures to prevent the water level from being too high or too low and causing adverse effects on crops.
3. Data analysis: By analyzing the data collected by radar water level meter, we can understand the changing law of canal water level and provide a scientific basis for irrigation management.
4. Water saving and emission reduction: The application of radar water level meter helps to achieve precise irrigation, reduce water waste, reduce farmland drainage, and reduce the impact on the environment.
A major irrigation channel in a major agricultural province has long used traditional manual observation methods to measure water levels. However, due to the high labor intensity, low accuracy, and inability to achieve real-time monitoring, manual measurement often leads to irrational allocation of irrigation water resources, affecting the normal growth of crops. In order to improve the efficiency of water resource utilization, the water conservancy management department in the region decided to use modern radar water level gauges to upgrade its water level measurement system.
1. Install radar water level gauges at key monitoring points in the irrigation channel and ensure that they are firmly installed to avoid vibration and other factors affecting the measurement results.
2. Connect the radar water level gauge to the data collector and set the data collector to record water level data at a predetermined time interval.
3. Transmit the collected data to the central control room through the communication network for remote monitoring.
4. Use professional software inside the central control room to analyze water level data, combine channel water conditions and weather forecasts, adjust the sluice switch, and reasonably allocate water.
After installing the radar water level gauge, the management department can grasp the changes in channel water levels in real time, adjust irrigation strategies in a timely manner, and effectively avoid wasting water resources.
By comparing the water usage before and after implementation, the project significantly improved the utilization rate of irrigation water and saved a lot of water resources.
At the same time, real-time monitoring data also provided a reference for channel maintenance and reduced emergencies caused by channel problems.
The radar water level meter measurement case successfully achieved real-time monitoring and management of irrigation channel water levels, which not only improved the efficiency of water resource utilization, but also enhanced the operational safety of the channel system.
This case proves the great potential and application value of radar water level meters in modern agricultural irrigation management, and provides a good reference for similar irrigation system upgrades.
