A radar water level meter is a common level-measuring instrument, which is widely used in various fields. In urban drainage systems, a manhole is one of the very important facilities for collecting and discharging rainwater and wastewater. And the water level measurement of manholes is a key part of manhole management and maintenance.
In this paper, we will analyze the application of a radar water level meter in manhole measurement, and discuss the difficulties of manhole measurement, and give actual measurement cases for analysis.
As part of the urban drainage system, manholes face some peculiarities in their water level measurement. Complex environment: Manholes are usually located underground in a complex environment with high humidity and temperature changes, which can interfere with water level measurement. Large range of water level changes:
The range of water level changes in manholes is usually large, and the water level changes significantly from dry wells to full wells, which requires measuring instruments with a large measuring range and high accuracy.
Dirt interference: There may be a large amount of dirt in the manhole, such as mud, sand, garbage, etc., which will interfere with the water level measurement instrument and affect the measurement accuracy and stability.
In a city drainage system, the water level measurement of manholes has been a challenge. The traditional measurement method uses a float-type water level meter, but due to the large amount of dirt in the manhole, the float is easily covered by dirt, resulting in an inaccurate measurement.
To solve this problem, they tried the application of a radar water level meter. Firstly, they selected a radar water level meter with a large measuring range and high accuracy, and reasonably installed and calibrated it according to the actual situation of the manhole. Secondly, for the complex environment of the manhole, they carried out protective measures, such as installing a waterproof cover and dust cover to protect the radar water level meter from humidity and dirt.
Finally, using the remote monitoring function provided by the radar water level meter, they realized the real-time monitoring and data transmission of the manhole water level.
Through data analysis, they can keep abreast of the water level changes in the manholes, which facilitates the management and maintenance of the drainage system. By using the radar water level meter, they have successfully solved the problem of manhole water level measurement.
Compared with the traditional float-type water level meter, the radar water level meter has the advantages of non-contact measurement and strong anti-interference, which can work stably in the complex environment of manholes and provide accurate and reliable water level measurement data.
Practical cases show that radar water level meter has great advantages in manhole measurement. It can not only work stably in a complex environment but also provide accurate and reliable water level data, which provides an important basis for manhole management and maintenance.
With the continuous development of technology, the application of radar water level meters in manhole measurement will be further improved and promoted to provide better support for the operation and management of urban drainage systems.
