中文版：据了解，液位计技术是目前仪器仪表行业技术发展的重要方向，只有极精密的液位计才能制造出应用设备。以前国产液位计只能造普通设备，对精度要求*的液位计产品就必须使用进口产业，而现在国产液位计也可以达到这一技术要求了。我国是世界消费*大国、制造*大国，同时也是进口*大国，而国产液位计产业以利润只有5%左右的中低端机床为主，进口的液位计产业利润则高达30%～40%。目前我国液位计市场进口产品占95%，我国为此每年需要花费100亿美元。目前，据统计我国固定资产达到1000万元以上的功能部件生产企业有70多家，占全部生产企业的10%以下。一是从研究院所、大专院校以技术支撑发展而来的企业，可称为“院所型”。这些企业的特点是：有一定技术基础和人才基础，有多项技术的发展潜力，但生产手段较弱，难以在短时间内形成产业规模，在成本、营销、服务等方面也存在一些差距；二是从主机厂逐步“独立”、“分离”出来的以生产某种功能部件为主发展起来的企业，可称之为“主厂型”。这些液位计生产企业在生产能力、工艺水平和使用经验上都可以适应市场需求，在一定程度上可以形成规模，但由于其与原主机厂有着千丝万缕的，在竞争中往往让用户产生疑虑，影响其市场开拓，同时，其开发能力也有一定的局限性，所以难以形成品牌；三是在江浙一带大量涌现出的民营企业，可称之为“民企型”。这些企业主要以劳动密集型、单一品种为主。由于竞争激烈，其质量和价格都能满足中低档液位计产业的市场需要。虽然这些品种的液位计产品尚不能制造，还需依赖进口，但在很大程度上，适应了我国仪器仪表行业目前发展的总体需求；还有一部分外商合资企业或独资企业生产部分较高水平的功能部件，但批量较小，且没有独立的技术开发能力，难以成为功能部件的主体和主流英文版：it is understood, liquid level meter technology is the important direction of the development of instrumentation industry technology, only a very sophisticated level gauge in order to manufacture equipment. previous domestic level meter can build common equipment, the level of high precision meter products must use the import industry, and now the domestic level meter can reach the technical requirements. china is the world's first power consumption, making the first big country, is also the first country imports, and domestic level meter industry profit is only about 5% in the low-end machine based, industry profit imports of high-grade liquid level gauge is as high as 30% ~ 40%. at present our country high-grade gauge market imported products accounted for 95%, therefore china costs $10000000000 a year. at present, according to statistics of china's fixed asset to the member 10000000 yuan of production more than 70 enterprises, production enterprises accounted for 10%. one is from the research institutes, universities support to technology development to the enterprise, can be called institutes. characteristics of these enterprises are: there are certain technical foundation and talent, the development potential of a number of technology, but the means of production is weak, it is difficult to form the industrial scale in a short period of time, cost, marketing and service, there are still some gaps; two is from the host plant gradually independent, separation. in the production of a functional component based development of the enterprise, can be referred to as the main plant type. the level gauge production enterprises can adapt to market demand both in production capacity, technological level and experience, to a certain extent, the formation of scale, but due to its original host plant has have all kinds of connections with contact, often in competition let users have doubts, affect the market development, at the same time, the development of the ability to have certain limitations, so it is difficult to form the famous brand; the three is in the area of jiangsu numerous private enterprises, can be called private type. these enterprises mainly in labor-intensive, single species. due to intense competition, its quality and price can meet the industrial grade level of the needs of the market. although these varieties of high-grade liquid level gauge products still cannot make, still need to rely on imports, but to a large extent, meet the overall demand the development of instrumentation industry in china; and in the production of high levels of functional component part of foreign joint ventures or wholly owned enterprises, but small volume, and there is no independent technical development capabilities, to become the main functional components and the mainstream
