With the sustained growth of the national economy; The rapid development of industrial production. Radar level gauges are widely used in industrial production processes. Due to the fact that radar propagation is not affected by the composition, concentration, pressure, temperature, etc. of the air medium, it is only related to the dielectric constant of the measured medium. It also has the advantages of easy installation, maintenance, and good interchangeability. More and more contact and ultrasonic measurement methods are being replaced by radar measurement methods. Throughout the past decade, the development of radar level gauges has mainly gone through the following stages:
1. In 2003, domestic radar was born in Beijing.
2. The second-generation radar of Taiwan was born in Beijing in 2006. Compared with the substitute products, although both belong to the 6GHz low-frequency radar, they adopt a simpler and guided Chinese English menu, have a dot matrix echo curve display, and have more powerful instrument software processing functions, making it possible to intuitively diagnose the instrument usage when debugging on the meter head.
3. After 2006, multiple domestic enterprises launched radar products.
4. Since 2008, more manufacturers have launched radar products, which still belong to domestic OEM products, mostly OEM products provided by the aforementioned manufacturers.
5. In 2007, the third generation radar level gauge product was developed and introduced in China. Its technology has reached the advanced level of similar products and belongs to the current mainstream products. The products being promoted by enterprises are also of this type.
6. In early 2008, after the last upgrade in replacement technology, no further technical improvements were made to the replacement product, and it was decided to stop promoting the product and instead sell it only as spare parts. The purpose is very clear, which is to guide users to provide higher quality and more reliable high-frequency radar products, in order to provide better services for users.
With the vigorous development of artificial intelligence and the Internet, the future level gauge will be more high-frequency and intelligent. With the improvement of technology and the upgrading of management, the production cost of liquid level gauges will be greatly reduced. More and more enterprises will also choose high-frequency intelligent products. It is believed that domestic liquid level gauge manufacturers will gradually replace brands such as E+H and Siemens, and gradually develop into true national brands.
