我国液位仪表液位计的研制在上世纪已经开始，国内作为液位仪表液位计重要的需求市场也越来越受到商家的关注，国内市场对质谱需求量的高速增长，却未把这一福音分蕙自家的企业，科研领域洋品牌垄断，国产仪器无奈不得不偏师经略，可仍无法摆脱尴尬境遇。液位仪表液位计的应用范围非常广，涉及食品、环境、人类健康、药物、国家安全、和其他与分析测试相关的领域。现已成为发展前景的分析仪器之一，近几年市场需求增长率超过10％，中国市场的需求增长远甚至还要大于这个比例。尤其目前人类健康、环境安全以及能源的合理利用等是当前世界各国面临的突出问题，液位仪表液位计也因其在分析检测过程中准确的定性和定量能力而受到格外青睐。然而这日渐繁荣的市场，却未给我们国产的仪器厂商带来太多的收益，据了解目前我国的中压力表*依赖进口，也就是说我们所青睐的多是些国外品牌，我国的市场也成为别国商家吸金的对象。这真的不是“蝇头小利”啊，一台液位仪表液位计国产的*的也要几十万，进口每台差不多都要100万到500万甚至更多，一所211工程大学光液位仪表液位计一项设备就需投入几千万，。但是这几千万又有多少是采购国内产品的支出呢？没有多少吧。北大、清华有国产液位仪表液位计吗？估计可能性不大，其它作为科研基地的高等院校呢？恐怕加在一起也不会超过十几台吧。那么这个超过10％的需求量都是给谁创造的，安捷伦？赛默飞世尔？还是沃特世？总之很少会轮到中国的品牌。然而国产仪器在性能、价格等方面均不敌外国产品，因而逐渐失去市场。为了维持生计，这些国有仪器厂逐步由独立设计生产演变成为外国产品装配和委托维修，技术力量和设备随之流失。 　 如此一来压力表行业国产品牌里便出现蜀中无大将的局面，我们承认在压力表领域我们和国外的技术存在差距，但导致国产仪器无人问津局面的罪魁就是——中国设备上得出的数据在无法得到认可，，这不仅仅是境遇的尴尬，说是悲哀亦不过分。虽然国产液位仪表液位计也占据着一小部分教育市场，不过多不是去搞科研用，而是作为一般的使用了，发挥的作用比模型强不许多。
英文版本：
design of a liquid level instrument level china has already started in the last century, china as a global level meter level meter important demand market is also more and more attention of traders, the domestic market of high-speed growth of the mass demand, but not to the gospel hui own enterprises, scientific research field of foreign brand monopoly, homebred instrument helpless to army management, still can not get rid of the awkward situation. the scope of application of liquid level meter level meter is very wide, involving food, the environment, human health, medicine, national security, and other test and analysis on related field. it has become one of the most promising analytical instruments, in recent years the global market demand growth rate of more than 10%, chinese market demand growth is far greater than the proportion of even. especially at present, human health, environmental safety and the rational utilization of energy is a serious problem faced by all countries in the world, but also because of its accurate analysis by the qualitative and quantitative ability in the detection process favored liquid level meter level meter. however, the market is prosperous, but did not give us a homemade instrument manufacturers bring too much income, according to the current understanding of the high-end pressure meter in our country totally dependent on imports, that is to say that we favour mostly foreign brand, our market has also become a foreign businessman aspiration of the object. this is not really petty profits ah, a level meter level meter made of the cheapest to hundreds of thousands, import each almost 1000000 to 5000000 or more, a 211 project university optical liquid level meter level meter a device will need to invest tens of millions of,. but the millions and how much is the domestic procurement of goods expenditure? there is not much. domestic level meter level meter: peking university and tsinghua university? estimation is unlikely, as other universities base? i'm afraid with more than a dozen stations together will not. so that more than 10% of the demand and to whom are created, agilent? thermo fisher? or voight? in short, rarely turn to brand china. however, domestic instrument in performance, price and other aspects are not the enemy of foreign products, it gradually lost the market. in order to make a living, these state-owned instrument factory gradually by the independent design and production become foreign product assembly and entrust maintenance, technical strength and equipment will be lost. so the pressure meter industry in domestic brands appeared shu no generals of the situation, we acknowledge the existence of the gap in the high-end pressure gauge field in our and foreign technology, the culprit but led to the situation of domestic instrument by is - the equipment derived data on international not recognized, this is not the only situation, embarrassed, said it is also not too sad. although the domestic level meter level meter also occupy a small part of the education market, but many not to engage in scientific research, but as a general use, play a role model for many strong than not.
