Thread Content

Radar level gauges enjoy a wide range of applications due to their advantages such as advanced algorithms, simple installation and calibration, and high precision; they have achieved excellent results in industries such as chemicals, petrochemicals, cement, mining, pharmaceuticals, food processing, water treatment, and hydraulics. I. Applications of DHE-RD radar level gauges in the chemical industry The chemical industry has very high requirements for liquid level measurement technologies. The high precision, large measurement range, high stability, and ease of installation of radar level gauges make them more advantageous over other measurement methods in this industry. In the chemical industry, there are mainly four types of tanks: horizontal tanks, spherical tanks, vertical tanks, and process tanks. Horizontal tanks in the chemical industry, with a diameter of around 1 to 4 meters ； The media are mostly hazardous substances with strong corrosivity, as well as being flammable and explosive. Due to its relatively small measurement range, a contact-type guided wave radar level gauge is chosen, as it is inexpensive and offers good cost-performance. If the medium is highly corrosive, a rod antenna radar level gauge can be used to ensure its corrosion resistance. Spherical tanks are also common in the chemical industry; their diameter is usually greater than 10 meters. They are often used to store hazardous substances that are under pressure, have strong corrosion resistance, or are flammable and explosive. Due to their large volume, non-contact radar level gauges are typically used for measuring their level, with a maximum range of up to 30 meters and an accuracy of ±3 mm. Vertical tanks are commonly used in the chemical industry to store media at atmospheric pressure. Their capacity range is quite large, typically between 10 and 30 m, and they often have internal floating roofs. When selecting a radar level gauge, it is necessary to consider whether there is a guide wave tube inside the tank; for tanks with such a guide wave tube, a contact-type guide wave radar level gauge can be used, while for those without one, a non-contact radar level gauge is appropriate. Process tanks have always represented a challenge in the chemical industry. These tanks are equipped with devices such as heating and stirring systems, which create conditions that prevent other measuring instruments from functioning properly. The non-contact flat-panel radar level gauge, on the other hand, is not affected by stirring or heating, allowing it to operate stably. II. Applications of the DHE-RD radar level gauge in the petrochemical industry. In the petrochemical industry. It is necessary to reliably measure the material level at different stages of the process, which places high demands on the measuring instruments. Radar level gauges, especially suitable for measuring hydrocarbons in the petrochemical industry. Since it is not affected by temperature, pressure, or density, it can also meet the measurement requirements of containers with large ranges and different sizes. The petrochemical industry mainly uses tank types such as horizontal tanks, spherical tanks, vertical tanks, and process tanks. First are the horizontal tanks; petrochemical plants have a large number of such horizontal storage tanks, with a capacity range of 2–4 meters, in order to ensure the efficient completion of the refining process. The key is to be able to obtain an accurate level reading of the contents in the tank at any time, so as to ensure the availability of the relevant media when needed. Both contact and non-contact radar level gauges can be used in this application. Contact radar is relatively inexpensive and offers good value for money. Rather than contact radars, they are typically used in medium environments with high corrosion resistance requirements or where deposits may form. Most spherical tanks in the petrochemical industry are used to store hydrocarbons. For ranges greater than 10 m, propane (liquefied gas) is the most common. It is a colorless, odorless, flammable gas. Propane is liquefied by compression and then stored in this high-pressure container to prevent it from vaporizing. A non-contact radar level gauge is usually used to measure its level height. The vertical tanks in the petrochemical industry are mainly used to store refined oil products. Their range is mostly between 20-30m. For example, gasoline and diesel are often stored in vertical tanks. At normal temperature and pressure, an accurate measurement can be achieved using a contactless radar level gauge. Process tanks in the petrochemical industry are usually at high temperatures. High-temperature contactless flat-panel radar is usually used to measure the level height. III. Applications of DHE-RD radar level gauges in the pharmaceutical industry. The equipment used for manufacturing drugs in the pharmaceutical industry is usually smaller than traditional chemical production equipment. The medium being measured is of high value, the measurement range is limited, space constraints exist, and high hygiene standards are required. All these factors necessitate highly precise container sensing technologies. Radar level gauges were developed precisely for use in such small reaction vessels or tank-type equipment. The vast majority of containers in the pharmaceutical industry are horizontal tanks or process tanks. Most of the container reaction media commonly used in the pharmaceutical industry are stored in these horizontal tanks, with a capacity range of 2–3 meters. Given the high requirements for hygiene, we usually use non-contact radar level gauges; however, in cases where hygiene requirements are not as strict, contact-type radar level gauges can also be employed. In the drug production process, there are usually also many buffer tanks. A mixing and reaction process occurs within the medium in the buffer tank. Therefore, there are often equipment such as mixers and submersible pumps inside the tank. Most measurements are carried out using contactless flat-panel radar level gauges; these gauges have strong signals and are not affected by splashing or sticking of the medium. It is particularly suitable for measuring this type of operation with stirring. IV. Applications of the DHE-RD radar level gauge in the food industry: In the food industry, then. The various liquid or paste-like foods we use every day are stored in containers of different sizes. In them, mixing or processing takes place; many of them are equipped with stirring devices, or severe condensation occurs that leads to the formation of deposits. Radar level gauges are not affected by deposits or condensates in the medium, and can meet the requirements of the food industry. Horizontal tanks, process tanks, and silos. The vast majority of liquid foods or beverages in the food industry are of this kind. Most of the liquid is stored in this horizontal tank. Or it could be food and beverages; during the brewing process, there is always a thick layer of foam present. Such as beer, milk, etc. A contactless flat-panel radar level gauge has strong signal penetration capability. It is very suitable for measuring such operating conditions. In food processing technologies, process tanks are also commonly used. Process tanks usually come equipped with devices such as agitators and heating systems. Due to stirring, the medium may splash, causing deposits to adhere to the antenna used for measurement, as well as to the antenna of the planar radar. The signal is strong and not affected at all by attachments; non-contact flat-panel radar is typically used to measure such conditions. Grain silos are also the most common storage tanks in the food industry. Grains are solid particles, and solid radar level gauges are typically used to measure them. It has a strong signal and can penetrate dust to measure materials. V. Applications of DHE-RD radar level gauges in the water resources industry: The water resources industry is the sector that makes the most use of radar level gauges. Since reservoirs have a relatively large capacity. This contactless radar level gauge is easy to install, convenient to use, and offers excellent cost-performance.
