Ultrasonic liquid level gauge is a non-contact liquid level measuring instrument. When it is actually working, the probe emits pulse wave. After reaching the liquid level surface, it is returned by the sensor. The time difference of sound wave transmission and reception is used to calculate the level gauge to be measured. Height, because it is non-contact measurement, the measured medium is almost unlimited, ultrasonic level gauges are widely used in the measurement of various solid materials and liquid level;
Currently, there are a large number of ultrasonic level gauge manufacturers in China, and the development of ultrasonic level gauge industry is relatively mature. In particular, ultrasonic level gauge products have been well developed. China's ultrasonic level gauge industry is developing rapidly, but in the context of a good industrial situation, some issues are also worth worrying about, especially the domestic manufacturers of ultrasonic level gauges mainly for low-level, small-scale, family workshop-style enterprises. the Lord. This is a big limitation and bottleneck for the future development of the ultrasonic level gauge industry in China.
In recent years, China's ultrasonic level gauges have been playing a good role in eliminating the inferior and demolishing new products. This is a sign of the healthy development of the instrument industry. Although the overall level of the instrumentation industry has been greatly improved, the quality is still not stable enough. For example, the phenomenon of running, running, dropping, and leaking often occurs in the domestic ultrasonic level gauge industry. Product saturation is accompanied by continuous increase in instrumentation, and the trend of ultrasonic level gauges is an international influence. Under the current situation, instrument and meter companies should timely adjust the product structure of ultrasonic level gauges, control investment scale, and compress non-productive expenditures. This is undoubtedly also positive.
In addition, there is still a certain gap between China's ultrasonic level gauge industry and developed countries. The market competition of ultrasonic level gauges has become increasingly intense, and the market for some ordinary ultrasonic level gauges has become saturated and there is a situation where supply exceeds demand. This has made the development of small and medium-sized enterprises more and more difficult. Even the products with relatively high technological content are very competitive in the international market.
Our ultrasonic level gauge manufacturer has a long history of battles. It has been hardships. Since its entry into the WTO in 10 years, it has suffered numerous setbacks overseas and suffered hardships. Although it has little success, it still cannot get rid of the indigestion and incompetence. The key issue is the international standardization strategy.
Domestic ultrasonic level gauge companies have always been not very clear about their positioning, blind production, and lack of matching and cooperation with the host company's product support. It can be said that most of domestic fastener companies' products are produced in batches according to the same standard. They do not care whether their products can meet the matching requirements of the mainframe products on the market. They are blindly pursuing their own factory volume, and foreign instrument brands. Compared with the products, what we lack is a dedicated dedication. In the development of the instrumentation and meter industry, the same development model can be applied. It can be one-on-one or even one-to-many.
Although some domestic companies have already begun to realize this, they have developed new product regulations, but this is only a small step in the progress. Ultrasonic level gauges are still to be promoted and perfected in the entire industry. The competition is so cruel. Today, the independence of ultrasonic level gauges in the market is indeed not an easy task. It is more due to the intensification of external competition and changes in the market. In order to successfully expand products in China, we must strengthen the construction of a marketing and management system based on the advantages of our products. We must improve our marketing execution capabilities so that our high-quality products can be accepted by the domestic market.
At present, in the ultrasonic level gauge market, the localization of high-end ultrasonic liquid level gauges has become very difficult. The current basic parts have become a shortcoming that restricts the development of domestic manufacturing to high-end development. During the 12th Five-Year Plan period, China will further increase the localization of high-end equipment components. The feasibility of importing and replacing ultrasonic level gauges in sub-sectors in China is very different. The high-end ultrasonic level gauge industry calls for more policy guidance and scientific research support. The future domestic ultrasonic level gauge industry presents a good development prospect.
A sealant is a substance used to stop fluids from passing through a seam or opening in a surface or material and is a type of mechanical seal. In building construction, sealants are sometimes synonymous with caulking and are also used to block the transfer of dust, sound and heat. Sealants can be weak or strong, flexible or rigid or temporary. Sealants are not adhesives, but some have adhesive properties and are called adhesive sealants or structural sealants.
Although not very strong, sealants have many properties. They seal the top structure to the substrate and are particularly effective during waterproofing by keeping moisture out of (or in) the components that use them. They provide thermal and acoustic insulation and can be used as a fire barrier. They may also have electrical properties. Sealant can also be used for simple smoothing or filling. They are usually required to perform several of these functions at a time.
A caulk sealant has three basic functions: it fills the gaps between two or more substrates; it forms a barrier through the physical properties of the sealant itself and its adhesion to the substrates. And it maintains hermetic properties over the life expectancy, usage conditions and environment. Sealants perform these functions through the correct formulation to achieve specific application and performance characteristics. However, aside from adhesives, there are few other functions that can replace the sealing process.
