中文版： 根据社会调查显示仪器仪表行业发展之所以能如此快速的进步，其原因不外乎以下几个方面：首先，整个国民经济的迅速发展，两化融合的进一步加深，带动了各个经济领域对自动化的需求，从而也带来了液位计产业的繁荣。具体来看，国家重点工程项目的实施，食品及医药安全等关系国计民生问题的凸显，都为在制造装备智能化、生产过程自动化以及质量监督检疫环节中起到至关重要作用的液位计提供了机遇。其次“十二五”期间，国内液位计产业技术的显著提高，致使部分国外*逐步被国内市场取代，增加了国产液位计的*。第三，我国市场对于液位计产业的需求使得许多跨国公司十分重视国内市场这块蛋糕，越来越多的国外生产企业开始在国内开设工厂。从此前需要进口的液位计产品转化为本土化生产，在一定程度上扩大了液位计产业的市场规模。然而，随着经济环境的持续恶化以及国内市场环境的不稳定性因素，国内很多产业出现的产能过剩的现象，致使液位计产业也开始呈现出降温趋势。“十二五”期间，仪器仪表行业将如何发展，成为国内各生产企业不得不关注的重点问题之一。英文版：according to social investigation shows the development of instrument industry has such rapid progress, the reason is that in the following aspects: first, the rapid development of the entire national economy, further enhance the integration of the two, driven by the demand for the automation of the various economic sectors, from but also brought liquidometer industrial prosperity. the specific point of view, the implementation of the national key projects, highlight the food and medicine safety relationship beneficial to the people's livelihood problems, provides opportunities for play crucial role in the level of manufacturing equipment, inligent, automation of production process and quality supervision and quarantine link. secondly, twelfth five year plan period, significantly improve the domestic level of industrial technology, resulting in some foreign market share gradually by domestic market instead, increase the domestic level of market share. third, china's market for liquid level meter industry demand makes many multi-national corporation attaches great importance to the domestic market this cake, more and more foreign enterprises began to set up factories in china. from the previous level meter products need to import into the localization of production, to a certain extent, expanded the level meter industry market size. however, with the continued deterioration of the economic environment factors and the domestic market environment of instability, many domestic industry overcapacity phenomenon, the level meter industry also began to show a decreasing trend. twelfth five year plan period, how the instrumentation industry will develop, become one of the key problems of domestic production enterprises have to concern.
