Cooling towers are widely used in industry and are equipment used to cool and recover heat by circulating water back and forth in a circular fashion. The level measurement of the cooling tower pool is also very important. In some cases, the use of traditional measurement methods does not accurately reflect the actual level of the cooling tower pool. At this time, the radar level meter becomes a common measurement instrument. This paper will introduce the considerations of using radar level meters to measure cooling tower pools, cover the measurement difficulties and problems that need attention, and give two actual measurement cases for analysis.
Different from ordinary storage tanks, cooling tower pools have some special characteristics, these characteristics in the liquid level measurement will bring many difficulties.
Mainly reflected in the following aspects: liquid level changes quickly, because the working principle of the cooling tower determines the cooling tower pool liquid level changes quickly, and the rapid change in the height of the liquid level will lead to the level measurement data being difficult to stabilize. Uneven internal distribution of the liquid level, the uneven internal distribution of the liquid level, easy to cause measurement errors, thus affecting the accuracy of the liquid level measurement.
The liquid evaporation is large, and the cooling tower pool is exposed to a large area of air, and its liquid surface has been exposed to a large amount of air, which will rapidly reduce the liquid level height through evaporation, which will easily make the measurement value wrong.
The radar level meter measuring the cooling tower pool should pay attention to the signal stability, because the liquid level changes quickly, the radar level meter must have good tracking performance to get a stable and lasting signal response.
Pay attention to the environmental impact, the surrounding environment of the cooling tower pool is harsh, such as temperature, humidity, and other factors can affect the measurement, the use of a radar level meter should pay attention to these influencing factors.
Pay attention to the accuracy of the instrument Should be based on the actual situation and requirements of the cooling tower pool, and choose the appropriate accuracy of the radar level meter design program.
For cooling tower pools in chemical plants, the accuracy of liquid level measurement is particularly important. After a period of operation of a plant, it was found that the liquid level was always low, which had a certain impact on the production process.
Through the use of a radar level meter, the technical staff found this problem in time. By adjusting the position of the equipment, the low level was properly handled while maintaining the function of the equipment to ensure the accuracy of production.
The cooling tower used in a power plant has a large capacity and the liquid level changes and fluctuates quickly. Level information is not accurately obtained using traditional level measurement methods.
By using a radar level meter, the liquid level in the cooling tower can be obtained very accurately, thus helping workers to better regulate work efficiency and production safety.
The level measurement of the cooling tower pool is very important, especially in the chemical industry, electric power, and other industries, more accurate need to obtain the level data to ensure production efficiency and safety.
The use of radar level meters can effectively solve the difficulties of the cooling tower pool level measurement, at the same time in the use of the need to pay attention to signal stability, environmental impact and instrument accuracy, and some other issues.
Through the analysis of actual measurement cases, it can be seen that the application of radar level meters can effectively help workers quickly and accurately obtain the liquid level information in the cooling tower pools, providing a strong guarantee for production management.
