中文版：近20年来国外液位计生产厂商早已把研究自动化规格做为发展的重点予以考虑，先后推出一批液位计产品投放市场。其所以受到客户的欢迎，主要原因是实现自动操作后，一是一名实验人员可以同时操作多台仪器，节省人力；二是由于液位计产业实现自动化后不必人机面对面操作，减少了对环境造成的污染，保障操作人员身体健康；三、液位计产业按照标准程序自动操作，减少人为的误差，可以提高测试精度。从国外液位计产业自动化的发展过程分析，大致可分为两个阶段，前段是标准规定的测试条件，将人工操作步骤实现自动化；后一阶段则是近年来发展较快的“另起炉灶”方法，即以研制出新仪器为核心，另行编辑新的测试方法标准的办法。尽管测试方法改变，但是新仪器测出新油品性能的结果必须直接或间接换算后才能与经典方法所测的结果基本一致。注意到上自动化液位计产业的发展动向和开发国内自动化规格仪器的必要性，如何将我国的液位计产业制造水平提升到一个新的平台，在安排手动规格仪器国产化的同时，从开发液位计产品规划起就注意将其与自动化的研发相结合，安排有条件的液位计生产企业负责研制，请有要求的仪器厂家共同承担，并在经费、试用、推广等方面创造必要的条件。因此，没有造成液位计产业的品种及加工水平与相差过分悬殊。当然，目前市场上见到的这些国产液位计产业还仅仅是上发展的前一阶段水平英文版:in the past 20 years foreign level meter manufacturers have already put the research of automation specification as the focus of development into consideration, has launched a number of level meter products on the market. it therefore welcomed by customers, the main reason is to realize the automatic operation, one is an experimental personnel can operate multiple machines, saving manpower; two is due to realize the automation of industrial liquid level meter can not be human face operation, reduce pollution to the environment, protect the health of the operating personnel; three, level meter industry according to standard procedures for automatic operation, reduce human error, and can improve the testing accuracy. analysis of the development process from the foreign level meter industry automation, can be roughly divided into two stages, some test standard, manual steps to achieve automation; later stage is developed rapidly in recent years, set up a separate kitchen method, namely, to develop a new instrument as the core, further editing standard test method the new approach. although the testing method of change, but the new instrument of new oil performance results must be converted to and directly or indirectly measured by the classical method results are basically the same. attention to the necessity of the international development trend of automation level of industry and development of domestic automation equipment specifications, how will the level in china manufacturing industry to a new platform, in the arrangement of domestic manual specification instruments at the same time, product planning will be automatic and r & d combination from the development of liquid level, liquid level arrangements conditional production enterprises responsible for the development, please have the requirements of equipment manufacturers together, and create the necessary conditions in funding, probation, promotion and so on. therefore, caused no liquid level meter industry varieties and processing level and international difference wide gap. of course, these domestic industry level currently on the market see meter is only a level of international development
