A brief discussion on the application of radar level gauges in the chemical industry

Thread Content

In the chemical industry, corrosive and hazardous media are quite common. This article addresses the various containers, different types of media, and complex measurement environments encountered in the use of radar level gauges in this industry. Based on the measurement principles and characteristics of radar level gauges, it outlines the key points to consider for their installation. Features of the measurement principle of radar level gauges: Radar level gauges use electromagnetic wave pulses for measurement, with an operating frequency of 26 GHz and low beam energy. They can be installed in various metal and non-metal containers or pipes, and are capable of continuously measuring the level of liquids, slurries, and granular materials. Suitable for environments with large fluctuations in dust, temperature, and pressure, as well as those containing inert gases and steam. Radar level gauges cause no harm to humans or the environment, and they also have advantages such as being unaffected by the specific gravity of the medium, unaffected by changes in dielectric constant, and requiring no on-site calibration. Radar level gauges transmit and receive extremely short microwaves with very low power through an antenna system. Radar waves travel at the speed of light. Operating time can be converted into a level signal through electronic components. A special time extension method can ensure stable and accurate measurements in an extremely short period of time. Applications of radar level gauges in the chemical industry: Spherical tanks are also common in the chemical industry; their diameter is usually greater than 10 meters. They are often used for storing hazardous substances that are under pressure, require strong corrosion resistance, or are flammable and explosive. Due to their large volume capacity, non-contact radar level gauges are typically used for measuring these tanks, with a maximum measurement range of 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 guide wave tubes, contact-type guide wave radar level gauges can be used, while for those without such tubes, non-contact radar level gauges can be employed. 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, however, is not affected by stirring or heating and can operate stably. Xi’an Dinghua Electronics Co., Ltd., established in 1992 and currently located in Xi’an, Shaanxi Province, is a high-tech enterprise that specializes in the research and development, production, sales, and engineering services of radar level gauges. At present, the company offers a range of products including radar level gauges, external liquid level meters, fork-type level switches, electro-hydraulic actuators, ultrasonic flowmeters, and external thermometers. All of these products have withstood numerous complex operating conditions in real-world scenarios, and they are widely used in industries such as petroleum, chemicals, power generation, coal, metallurgy, as well as food and pharmaceuticals.
