The liquid level sensor market will exceed 1.2 billion yuan in 2013

According to statistics, by 2013, the overall market size of China's Internet of Things will reach 750 billion yuan. As the bottom layer and the most basic link of the “Pyramid” of the Internet of Things, the sensor industry of liquid level gauges will directly benefit.

The development of the Internet of Things is inseparable from the development of liquid level sensor technology. However, at present, the development of industrialization of liquid level sensors still poses no small challenge. It is reported that there are more than 1,700 enterprises engaged in the production and research and development of liquid level sensors in China. The annual output of liquid level sensors has exceeded 2.4 billion, and the liquid level sensor products have reached 10 categories, 42 subcategories and more than 6,000 varieties, showing good results. The trend of development, but in this enterprise, foreign-funded enterprises have obvious advantages, the proportion of foreign-funded enterprises reached 67%, especially Japan, the United States, South Korea and Germany, the proportion of state-owned enterprises and ethnic enterprises accounted for only 33%. Domestic and foreign enterprises have a wide range of comprehensive strengths, small scale, shortage of talents, and weak R&D capabilities, which make it difficult to compete with foreign companies.

In recent years, the domestic market for magnetic level gauge sensors has been continuously growing at speeds exceeding 10%. In 2010, sales of liquid level sensors in China reached 90.5 billion yuan. It is predicted that the Chinese liquid level sensor market will develop steadily and rapidly over the next five years. Under the impetus of the large-scale growth of the Internet of Things market, China's liquid level sensor market is expected to reach over RMB 1.2 billion in 2015.

More crucially, technically, the domestic liquid level sensor technology is weak. First, the core technologies and basic capabilities are lacking. The core chips are heavily dependent on foreign imports. Domestic companies are significantly different from foreign companies in terms of high-precision, high-sensitivity analysis, component analysis, and high-end special applications. The second is the lack of unified standards and independent intellectual property rights in terms of design, reliability, and packaging. There have been no breakthroughs in interfaces, deep etching, high-temperature ohmic contact, highly reliable MEMS packaging, rapid testing, and high-simulation simulation technologies. Industrialization verification; Third, the product is not comprehensive enough in variety, specification, and series, and there are still some differences in the measurement accuracy, temperature characteristics, response time, stability, reliability and other technical indicators, so China float level gauge Sensor companies have a long way to go.
