Radar level meter is a kind of liquid level measuring instrument widely used in industry, in the photovoltaic power plant, the molten salt storage tank is an important equipment, used to store the heated liquid salt. Radar level meter has many advantages and features in the level measurement of molten salt storage tank in photovoltaic power plant.

First of all, the molten salt storage tanks in photovoltaic power plants are usually located in high-temperature and high-pressure environments, and the radar level gauge can work normally under extreme temperature and pressure conditions. Its wide measurement range can be adapted to molten salt storage tanks of different specifications and capacities, with high adaptability and flexibility. Secondly, the radar level meter is not affected by the physical properties and state of the liquid, and can accurately measure the level of molten salt whether it is in liquid or solid state. This ensures that the photovoltaic power plant can accurately monitor the level change of molten salt under different working conditions to ensure the stability and safety of the process. Again, the radar level meter has the characteristic of non-contact measurement, which can avoid the wear and corrosion problems caused by the traditional contact level meter due to long-term media contact. This is especially important for special media such as molten salt, which can extend the service life of the equipment and reduce maintenance costs.

Below are two examples of actual measurement cases to illustrate the application of radar level meter in the level measurement of molten salt storage tank of a photovoltaic power plant. Case 1: Molten salt storage tank level measurement in a photovoltaic power plant The photovoltaic power plant uses molten salt as the heat medium, which is stored and transported through the storage tank. As molten salt has the characteristics of high temperature and high viscosity, the traditional liquid level meter cannot meet the requirements. Therefore, the plant adopts radar level meter for liquid level measurement. The radar level gauge sends a high-frequency pulse signal into the molten salt storage tank, and when the signal hits the surface of the molten salt, it is reflected back. The level of the molten salt is obtained by calculating the round trip time of the signal. Through the use of radar level meter, the power plant successfully solved the molten salt storage tank level measurement problems. Due to the non-contact measurement characteristics of the radar level meter, it does not need to be in direct contact with the molten salt, which can avoid the wear and corrosion of the equipment and improve the reliability and stability of the equipment.

Case 2: Molten Salt advanced tank level monitoring in a Photovoltaic Power Plant The molten salt tanks in a photovoltaic power plant have large level fluctuations due to design defects. In order to keep abreast of the level changes of molten salt, the plant introduced radar level meter for level monitoring. The radar level meter can monitor the liquid level of molten salt in real time, and when abnormal fluctuations in the liquid level are found, it can give an alarm in time to ensure the stability and safety of the process. At the same time, the radar level meter can also record the historical data of liquid level changes, which is convenient for later analysis and optimisation of the process. Through the application of radar level meter in the molten salt storage tank of the photovoltaic power plant, the plant has successfully solved the problem of unstable liquid level and improved the controllability and safety of the process. The radar level meter has many advantages in the level measurement of molten salt storage tanks in photovoltaic power plants, including adaptation to extreme environments, non-contact measurement and high accuracy. Through the introduction of practical application cases, it can be seen that the importance and value of radar level meter in the photothermal power plant, providing a reliable means of liquid level monitoring for industrial production.
