Analysis Of Key Factors in Selecting Liquid Level Measurement Sensors For Nuclear Power Plants

The application of liquid level meters varies in different industrial sites. For example, in sewage treatment plants, liquid level meters are used to measure the liquid level of sewage. In power plants, liquid level meters are used to measure the liquid level of raw materials for power generation. In nuclear power plants, the selection of liquid level meters is particularly important because they need to be able to accurately measure the liquid level of specific media such as desalted water, boric acid, boric water and seawater. These media are not only highly corrosive, but also have specific dielectric constants, so the selection of liquid level measurement sensors must consider the chemical properties of the medium, especially the influence of its corrosiveness and dielectric constant.

For example, for the circulating water filtration system of a nuclear power plant, the medium usually measured is seawater, which is highly corrosive and may produce steam and foam during the measurement process. For this reason, the selection of liquid level meters in nuclear power plants is crucial. For low dielectric constant liquids, ultrasonic level meters or guided wave radar level meters can be considered; for corrosive liquid media, high-frequency radar level meters can be considered.

In addition, the operating environment of a nuclear power plant is also one of the factors that need to be considered when selecting a liquid level measurement sensor. Many liquid level measurement occasions are in high temperature environments, and some even have radiation or mechanical components. In this complex and changing environment, the selection of a suitable nuclear power plant liquid level meter must be based on the specific measurement medium and operating conditions. For example, for liquid level measurement under high temperature conditions, a radar level meter that is almost unaffected by temperature and pressure can be considered.

Therefore, the selection process of a nuclear power plant liquid level measurement sensor is similar to that of other plants, and it is necessary to comprehensively consider the characteristics of the measurement medium, the operating environment, and the required range. This customized liquid level meter selection operates stably and reliably in various process environments of nuclear power plants.
