Radar liquid level meter is widely used in power plant fire water storage tank level measurement. Fire water storage tanks in power plants have the following characteristics: large capacity, large level changes, liquid properties, liquid temperature changes, etc..

First of all, the capacity of fire water storage tanks for power plants is usually large, generally calculated in hundreds of cubic metres. 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 sufficient 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 gauge 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, and it is necessary to regularly replenish the water level 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 gauge needs to have a high measurement accuracy, can accurately measure small changes in the level, and can monitor the rapid changes in the level in real time. In addition, the liquid in the fire water storage tanks of power plants 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, 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 variation. For example, the water temperature may be higher in the summer high temperature situation, while in the winter low temperature situation, the water temperature may be lower. Radar level gauges need to have good temperature resistance to ensure that the level can be measured accurately at different temperatures.

The following are two examples of actual measurements: Case 1: Measurement of the level of a fire-fighting water storage tank in a power plant The fire-fighting water storage tank in the power plant has a capacity of 200 cubic metres, and a radar level meter is used for radar level measurement. Under normal conditions, the level varies between 80 metres and 150 metres. Through the real-time monitoring system, the staff can obtain the liquid level data at any time, so as to judge whether there is enough water in the storage tank. In the event of a fire, the staff can learn about the liquid level changes in time so that they can take appropriate measures to ensure that the fire is extinguished. Case 2: A power plant fire water storage tank level monitoring the power plant fire water storage tank capacity of 500 cubic metres, the level of a wide range of changes. 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 the reliable supply of fire water.

Through the above two actual measurement cases, we can see the importance and application value of the guided wave 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 meter will continue to improve, and bring more convenience and reliability for the measurement of the level of fire water storage tanks in power plants.
