中文版： 液位计在仪器仪表产品中占有相当大的比重。据国外工业发达国家统计，液位计的产值是压缩机、风机和泵三者的总和，约占整个机械工业产值的5%。同时，作为重大技术装备的重要组成部分，尤其是在电力、石化、冶金、城市供排水系统中，液位计更是起着关键作用，而且用量非常大。据空调制冷大市场专家分析，造成目前我国液位计市场被动的原因主要有两方面：一是国产液位计产品和进口产品比还有差距，质量有待提高；二是某些用户国产化意识不强，甚至人为地设置门槛，使国内企业在与国外企业竞标时难以中标。根据相关人员透入我国企业目前生产的各种液位计普遍存在着外漏、内漏、外观质量不高、寿命短、操作不灵活以及液位计电动装置和气动装置不可靠等缺点，部分产品只相当于上个世纪八十年代初的水平。因此，发展液位计工业，亟待开发技术含量高的新产品。有关专家要求，液位计行业应大力采用标准和*标准，严格贯彻现有的国家标准，对现有产品进行改革，使更新后的产品达到上个世纪九十年代水平。同时，阀门行业应对铸锻件的原材料选用、铸造工艺、锻造工艺、热处理等环节采取有效措施，使铸锻件毛坯在内在质量和外观质量达到水平。另一方面，应继续开展内、外漏攻关，严格机械加工工艺，大力推广新型密封材料，提高产品关键部位的加工精度，延长产品使用寿命，使阀门'一短两漏'现象根本性好转。纵观国内液位计市场，液位计行业有着广泛的发展空间，据有关专家预测，液位计未来市场主要在电力工业、石油化工、化肥、环保和城建等行业。他们断言，谁有好的技术，谁有过硬的质量，谁能不断开发新产品，谁就能在激烈的市场竞争中抢得先机、脱颖而出。英文版：liquid level gauge occupies a large proportion in instrumentation products. according to foreign industrial statistics, level of output is the sum of the compressor, fan and pump three, accounting for the machinery industry output value of 5%. at the same time, as an important part of major technical equipment, especially in electric power, petrochemical, metallurgy, city water supply and drainage system, liquid level gauge is also plays a key role, but the amount is very large. according to the analysis of air conditioning and refrigeration big market experts, resulting in the current our country level gauge passive market mainly in two aspects: one is the domestic level meter products and imported products than there are gaps, the quality to be improved; the two is some users localization is not strong, even artificially set the threshold, so that domestic enterprises in the bidding is difficult to bid with foreign enterprises. various level according to relevant personnel into china's current production of enterprises plan widespread leakage, internal leakage, appearance quality is not high, short life, the operation is not flexible and liquid level gauge electric devices and pneumatic devices are not reliable shortcomings, some of the products is equivalent to eighty years on behalf of the international level of the early last century. therefore, industrial development, urgent need to develop new products with high technology content. relevant experts, should vigorously adopt international standards and foreign advanced standards of industry level gauge, strictly implement the existing national standards, the reform of existing products, the updated product to reach the last century ninety's international level. at the same time, the valve industry should forging of raw materials selection, casting, forging, heat treatment and other sectors to take effective measures, make casting blank in the inner quality and appearance quality to meet international standards. on the other hand, should be continued, the leakage research, strictly mechanical machining process, to promote new sealing materials, improve product processing precision of key parts, extend product life, so that the valve 'short' two leakage phenomenon fundamentally improved. the market throughout the domestic level meter, level meter industry has a broad development space, according to experts predict, liquid level gauge future market mainly in the power industry, petrochemical, fertilizer, environmental protection and urban construction and other industries. they assert, and who has good technique, and who has excellent quality, who can constantly develop new products, who will be able to seize the opportunity, talent showing itself in the fierce competition in the market.
