A radar level meter is widely used in power plant fire water storage tank level measurement. Fire water storage tanks in power plants are characterized by the following features: large capacity, large level changes, diverse liquid properties, and large changes in liquid temperature.
First of all, the capacity of fire water storage tanks in power plants is usually large, usually calculated in hundreds of cubic meters. This is because the fire water storage tanks of power plants need to meet the demand for a large amount of water at one time, in order to ensure that enough water can be provided in time to extinguish fires and other emergencies.
Therefore, in view of this large capacity, the range of the radar level meter needs to choose a larger range to ensure the accurate measurement of the liquid level.
Secondly, the level of fire water storage tanks in power plants varies greatly. Despite the large capacity of the storage tank, in practice, due to a long period of unused or other factors, the water level in the tank may drop to a lower level, which needs to be replenished periodically by means of water supply.
And in the event of a fire, it is necessary to evacuate a large amount of water as soon as possible to extinguish the fire.
Therefore, the radar level meter needs to have high measurement accuracy, can accurately measure small changes in level, and can monitor the rapid changes in level in real-time.
In addition, the liquid in the fire-fighting water storage tank of the power plant is diverse in nature and may be water from different sources such as tap water, rainwater, river water, and so on.
There may be differences in the properties of water liquids from different sources, such as conductivity, dielectric constant, and so on. Therefore, the radar level meter needs to have a strong adaptability and can be accurately measured for different liquids, to provide reliable level data.
Finally, the temperature of the liquid in the fire-fighting water storage tank of the power plant may have a large range of variations.
For example, the water temperature may be higher in the high-temperature situation in summer, while the water temperature may be lower in the low-temperature situation in winter.
Radar level meters need to have good temperature resistance to ensure that the level can be measured accurately at different temperatures.
The following are two actual measurement cases:
Case 1: Measurement of fire water storage tank level in a power plant The fire water storage tank in the power plant has a capacity of 200 cubic meters, and a radar level meter is used for level measurement. Under normal conditions, the level varies between 80 meters and 150 meters. Through the real-time monitoring system, the staff can obtain the liquid level data at any time, so as to judge whether the water volume in the storage tank is sufficient. In the event of a fire, the staff can be informed of the liquid level changes in time, so as to take appropriate measures to ensure that the fire extinguishing is carried out.
Case 2: a power plant fire water storage tank level monitoring the power plant fire water storage tank capacity of 500 cubic meters, the liquid level changes in a wide range. Through the real-time monitoring system of the radar level meter, the staff can understand the trend of the liquid level in the tank so as to replenish the water source in time. In addition, through the statistics and analysis of the liquid level data, the staff can understand the water consumption of the storage tank, so as to carry out reasonable management and scheduling and ensure a reliable supply of fire water.
Through the above two actual measurement cases, we can see the importance and application value of the radar level meter in the measurement of the liquid level of fire water storage tanks in power plants.
It can measure the liquid level in real time and accurately, which is of great significance for the comprehensive management and safe operation of fire water in power plants.
With the continuous progress and innovation of science and technology, it is believed that the performance and function of radar level meters will continue to improve, which will bring more convenience and reliability for the measurement of the level of fire-fighting water storage tanks in power plants.
