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.                                                                                                                                                                                           (Image source: Internet)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.

Solid-matched slurry material storage tanks are usually used to store granular materials such as cement, slag, coal ash, etc. and have some unique characteristics. Radar level meter has a wide range of applications in measuring the level of solid slurry material storage tanks, which can achieve accurate and reliable measurement. The following will introduce the characteristics of solid matching slurry material storage tanks, and combined with two actual measurement cases to illustrate the application of radar level meter.Solid-matched slurry material storage tanks are usually characterised by large capacity, high height and large diameter. As the material in the tank is granular, it has a certain particle size and compressibility. Moreover, due to the large weight of the material, it is easy to cause measurement errors. In addition, in solid-matched slurry material storage tanks, the material will agglomerate or accumulate over time, resulting in a non-uniform distribution of the material level. Therefore, for this material with special properties, a highly accurate and reliable measurement method is needed to ensure the accurate positioning of the tank level.                                                                                                                                                                                        （ Image Source:Web）Practical example 1: In a concrete mixing plant, the level measurement of the slurry material storage tanks is very important. The traditional manual measurement method is not only inefficient, but also susceptible to environmental and human factors. By installing a radar level meter, the level measurement can be automated. Radar level meter has height adjustable antenna, can be adjusted according to the height of the tank, to ensure the accuracy of measurement. Moreover, the radar level meter has anti-interference performance, which can avoid the influence of cement dust and other environmental substances on the measurement results. Case 2: In a thermal power plant, the level measurement of coal ash storage tanks is also very important. Coal ash is a solid waste from a thermal power plant, with a certain particle size and fluidity. Conventional level meters cannot meet the requirement of accurate positioning of the coal ash level. By installing radar level meter, real-time monitoring of coal ash storage tank level can be achieved. Radar level meter has the characteristics of fast response, can accurately measure the height of dynamic changes in the material level. And radar level meter has good anti-condensation performance, can cope with the coal ash in the storage tank caking situation.Radar level meter has unique advantages in measuring the level of solid matching slurry material storage tanks, which can adapt to changes in temperature, pressure, humidity and other environmental conditions in the tank to achieve accurate and reliable measurement. At the same time, the radar level meter has simple installation and maintenance, which greatly improves the work efficiency. Therefore, radar level meter is undoubtedly an ideal choice in the application of level measurement of solid-matched slurry material storage tanks.

When purchasing a rotary stop level switch, many purchasers often ask what the criteria for purchasing a rotary paddle level switch is, or what the key to measuring a rotary stop level switch is. In fact, among the many components of a rotary stop level switch, the motor is the key to measuring the goodness of a rotary stop level switch.First, from the working principle of the rotary material level switch　　As a kind of level switch used for solid material detection, the rotary material level switch makes use of micro-motor as the driving device, which is connected with the blade drive shaft through the clutch. When the blade does not touch the material, the motor keeps running; on the contrary, when the blade touches the material, the motor stops rotating and cuts off the power supply of the motor, and at the same time outputs a switching signal to control the material delivery. If the material falls, the resistance of the blade also disappears, the blade relies on the torsion spring equipment to return to the normal rotation of the detection state.From the above working principle of the rotary level switch, it is easy to see that the motor is decisive for the stability and reliability of the rotary level switch. Not only that, a large number of practical cases also fully proved that the motor is the key to measure the good or bad rotary switch.Second, from the rotary material level switch failure causes　　In the safety control rigorous industrial application site, the reason why the rotary material level switch failure is frequent, and its use of unqualified poor-quality motor has a great relationship. Failures caused by the use of substandard motors are common:　　1. The torque of the motor is insufficient, which can easily lead to false alarms;　　2. The motor coil is easy to burn off, resulting in the scrapping of the instrument;　　3. The motor is light in weight and cannot eliminate the self-fluttering phenomenon in the operation of the instrument, which affects the working stability of the instrument;　　4. The motor deceleration device wear fast, easy to gear bite, or because of parts rupture, resulting in the motor can not work.　　It can be seen that the motor is good or bad on the stability of the rotary material level switch has a direct impact. This reminds purchasers in the purchase of rotary paddle type level switch, we must pay attention to whether the motor is qualified, high quality. Generally speaking, when selecting the motor, it is necessary to consider the structure of the motor, power, speed, deceleration mechanism, temperature rise and other factors. However, many domestic instrumentation manufacturers to cope with the competition, a price war, most of the selection of domestic low-quality motors to control production costs. The internal deceleration device of the inferior cheap motor is mostly plastic gears, thin parts, coil is too thin and substandard materials, so that the rotary material level switch of the whole product performance and reliability are greatly reduced. This makes the instrument user in the purchase of cheap instruments, seems to take advantage of a great deal cheaper, but the poor quality of the product, its performance and reliability greatly affected, in turn, will cause great losses to the production. Therefore, the pursuit of low prices is not worth the loss.KDSS86 series rotary paddle type level switches are designed with high-quality motors and microswitches, and the rotary shafts are equipped with bearings, while focusing on the details of the process, strict control of the production process and quality inspection, which has higher reliability than similar products in China, and its stable performance in practice has been favoured by the users.

Radar level meters are a commonly used technique for measuring wave height on floating drilling rigs. A floating drilling rig is a common offshore engineering facility that is often used for deepwater drilling, oil development and other offshore construction projects. Since the height of the rig is relatively fixed, measuring the height of the waves is critical to ensuring the safety and efficiency of the rig.Radar level meters are a non-contact measurement technology that utilizes the return time of electromagnetic waves to measure the height of the liquid level. Radar level meters are suitable for a variety of complex environments, including marine environments. Compared with other measurement methods, radar level meter have the following characteristics: High accuracy: radar level meters can provide highly accurate measurements, and the accuracy can usually reach the millimeter level. This is important for measuring wave heights, as even small changes in waves can have a significant impact on rig stability and operational efficiency. Rapid Response: Radar level meters can monitor changes in wave height in real time and transmit the data to the rig's monitoring system. This rapid response helps the platform operator to make timely decisions and adjust the platform's attitude to adapt to wave changes, ensuring platform stability and continuity of operations.                                                                                                                                                                                     （ Image Source: Internet）The following are two examples of real-world measurements to illustrate the use of radar level meters to measure wave heights on floating drilling rigs. Case 1: Deep-sea drilling rig An international oil company is conducting a deep-sea drilling project, and they are using radar level meters to measure the wave height on a floating drilling rig. In deep-sea environments, the waves can change dramatically, so it is important to accurately measure wave heights in a timely manner to ensure the safety and smooth operation of the operation. Through the guided wave radar level meter installed on the drilling platform, the staff can monitor the change of wave height in real time. If the height of the waves exceeds the platform's safety limits, the system will automatically sound an alarm and provide appropriate advice, such as slowing down or stopping the drilling operation, to ensure the safety of the platform and the crew.                                                                                                                                                                                    （ Image Source: Internet）Case 2: Marine Construction Project An offshore engineering company is working on a large marine construction project where they are utilizing a floating drilling rig for foundation construction. During the construction process, they used radar level meters to measure changes in the height of the waves and combine the data with other measurements for real-time analysis and monitoring. By accurately measuring the height of the waves, the engineering company was able to adjust the position and attitude of the platform in time to adapt to the construction needs under different sea conditions. This effectively improves construction efficiency and safety, and reduces potential risks and downtime.The radar level meter is an effective tool for measuring wave height on floating drilling rigs. It features high accuracy and fast response, which can help ensure the stability and operational efficiency of the rig. Through the introduction of actual measurement cases, we can see the important application of guided wave radar level meter in marine engineering and construction projects. These cases not only show the practical effect of radar level meter, but also highlight its great potential in the field of marine engineering.
