Radar level gauges are widely used in environments where the accuracy of the electronic control unit and antenna plays a crucial role. However, slight variations in performance can occur due to factors such as microwave signal accuracy within the tank and internal interferences. These issues can significantly affect measurement results. The main contributing factors include:
1. Impedance mismatch at the antenna connection point.
2. Obstacles inside the tank that interfere with signal reflection.
3. Multiple reflections from the tank walls, roof, and bottom.
4. Surface ripples on the liquid causing signal distortion.
Additionally, the dielectric properties of the measured liquid also influence the radar level gauge's performance. Liquids with low dielectric constants may result in shorter measurement ranges and reduced accuracy, while high dielectric constant liquids allow for longer measurement distances and improved precision. As the petrochemical industry continues to evolve, radar level gauges have also advanced, offering specialized models designed for different application requirements. Depending on the desired level of accuracy, users can choose between industrial-grade or high-precision radar level gauges.
Radar level gauges are particularly suitable for challenging environments where traditional mechanical methods are difficult to apply. They are ideal for applications requiring high accuracy, such as:
1. Measuring levels of flammable, explosive, or corrosive media, especially in large vertical and spherical tanks.
2. Operating under a wide range of pressures, from vacuum to several megapascals, and temperatures from 0°C up to 400°C.
3. Offering different levels of accuracy to meet specific measurement needs.
4. Accommodating various tank types, including spherical, vaulted, external floating roof, and internal floating roof tanks.
Each type of radar level gauge has unique performance characteristics. The choice of model depends on the specific application, including temperature, pressure, corrosion resistance, and available space. For wide-range measurements, conical antennas are commonly used on buffer tanks or storage tank tops, while waveguides help extend the measurement range. Parabolic antennas are ideal for long-distance measurements in both liquid and solid materials. Small-angle antennas are suitable for narrow vessels, and planar antennas provide flexibility for various conditions.
Moreover, radar level gauges operate based on an empty-space measurement method. The liquid level is determined by measuring the distance from the top of the tank to the liquid surface and subtracting the reference height. However, static pressure and temperature fluctuations can introduce measurement errors. To ensure accurate readings in critical applications, it is recommended to integrate radar level gauges with multi-point temperature and pressure transmitters in large tank level measurement systems.
Microfiber Material In Roll
Microfiber fabric is a new textile material with high technology and high added value. It is mainly made of very fine fibers (usually between 0.1 microns and a few microns in diameter) and has the following characteristics:
​1. ** High water absorption ** : Microfiber fabric because of its small fiber diameter, can absorb a lot of water, several times higher than ordinary cotton fabric.
​2. ** Soft and comfortable ** : Due to the large gap between the fibers, the touch is very soft, good air permeability, high comfort.
​3. Strong wear resistance ** : The fiber structure of microfiber fabrics is tight, the wear resistance is far more than that of traditional fiber materials, and it is not easy to pilling.
​4. ** Anti-wrinkle ** : Fabric is not easy to produce wrinkles, easy to take care of.
​5. ** Antistatic ** : Due to its special chemical and physical properties, microfiber fabrics can effectively reduce the generation of static electricity.
​6. ** Environmental protection ** : In the production process, microfiber fabrics are environmentally friendly and have less impact on the environment.
​Microfiber fabrics are widely used in clothing, household goods, medical and other fields, such as the production of high-end clothing, bedding, baby diapers, surgical gowns, etc., because of its excellent performance and welcomed by the market.
