中文版本： 隨著國內(nèi)工業(yè)自動化、信息化和國防現(xiàn)代化的發(fā)展，液位計產(chǎn)業(yè)的年需求量持續(xù)增長。由于國內(nèi)液位計產(chǎn)業(yè)技術(shù)的創(chuàng)新和新產(chǎn)品開發(fā)能力落后于*水平，制約了工業(yè)自動化和信息化技術(shù)的發(fā)展。液位計產(chǎn)業(yè)的基本原理不難，但制造工藝技術(shù)嚴格保密。國內(nèi)液位計技術(shù)落后的根本原因是制造工藝技術(shù)和工藝設(shè)備的落后，使液位計產(chǎn)業(yè)的穩(wěn)定性和可靠性問題長期得不到根本解決，限制了國產(chǎn)液位計產(chǎn)業(yè)的使用范圍和可信程度。與國外液位計特別是高技術(shù)含量的液位計相比，國產(chǎn)液位計存在較大的差距。主要性能指標與國外差1～2個數(shù)量級。經(jīng)過多年開發(fā)，雖然一批工藝和產(chǎn)品取得了科技成果，由于批產(chǎn)工藝的穩(wěn)定性和實用性得不到很好解決，成為液位計產(chǎn)業(yè)化的瓶頸。 為此，必須加快發(fā)展液位計制造工藝技術(shù)和產(chǎn)品。而且可以做成三維運動結(jié)構(gòu)和復(fù)雜的力平衡結(jié)構(gòu)，使液位計技術(shù)從單一的物性型進入以微電子和微機械集成技術(shù)為主導(dǎo)的發(fā)展階段。隨著的參數(shù)檢測的需要和網(wǎng)絡(luò)化技術(shù)的發(fā)展，液位計產(chǎn)業(yè)將成為今后研究的熱點。目前，液位計產(chǎn)業(yè)技術(shù)的發(fā)展正處于由傳統(tǒng)型向新型液位計發(fā)展的關(guān)鍵階段，這是液位計產(chǎn)業(yè)發(fā)展的重大變革。英文版本：With the domestic industrial automation, informationization and modernization of the national defense development, the annual demand level meter industry continues to grow. Because domestic liquidometer industrial technology innovation and new product development ability behind the international advanced level, restricted the development of industrial automation and information technology. The basic principle of ,liquid level meter industry is not difficult, but the manufacturing process strictly confidential. The fundamental reason of domestic level of technology behind the production process technology and process equipment backward, so that the level of stability and reliability of the industry's long-term not fundamentally solved, limiting the scope of use of domestic level meter industry and believable degree. With the foreign level meter especially level high technology content meter compared, there is a big gap between the domestic level meter. The main performance indexes and foreign difference is 1 to 2 orders of magnitude. After years of development, although a number of processes and products made scientific and technological achievements, because the stability and practicability of the batch production process is not well resolved, become the bottleneck of industrialization level meter. Therefore, we must speed up the development of liquid level meter manufacturing technology and products. It can be made into a 3D structure and complex equilibrium structure, so that the liquid level meter technology from the property type single entry to microelectronics and micromachining technology development phase leading. With the development needs of the full range of test parameters and network technology, liquid level meter industry will become the hotspot of future research. At present, the development level of industrial technology is in the key stage from traditional type to a new level of development, this is a great change of liquid level meter industry development.
