Environmental Protection Engineering
烟气，废液、污水等的排放 ， 严 重 污染 了 大气和水资源，严峻威胁 着 人类 的 生存环境。 Due to the discharge of smoke, waste liquid, sewage, etc. , it seriously pollutes the atmosphere and water resources and seriously threatens the living environment of human beings . 据 科学 统计 ，在所用的 100多种流量计 中绝大一部分 是应科研之需用的，它们并不 是 批量出产， 也不 在市道市情出售，很多科研机构和大企业 都 设专门小组研制专用的流量计 。 According to scientific statistics , most of the more than 100 flowmeters used are for scientific research. They are not produced in batches or sold in the market. Many scientific research institutions and large enterprises have special The team developed a dedicated flow meter . 不仅 难度极大， 而且 品种繁多。 Instrument development is not only extremely difficult, but also a wide variety. 要将 空气和水的污染得到控制， 必须要 加强治理，而治理的基础是污染量的定量控制。 To control air and water pollution, governance must be strengthened, and the basis of governance is quantitative control of the amount of pollution. 虽然 是共通的 ， 但是仪表原理及结构以及使用前提 却 有很大 的 差别。 Although the physical principles and fluid mechanics foundations on which the flow meter and flow meter are based are common , the principle and structure of the instrument and the prerequisites for use are quite different. There are many substances to be monitored and measured in biotechnology, such as blood and urine.
是 生命科学的世纪，生物技术为特征的工业将获得 飞速 发展。 The 21st century will be the century of life sciences, and industries characterized by biotechnology will develop rapidly . 是 烟气排放 的 控制，每个烟囱 必须要 安装烟气分析仪表和流量计 ， 以便 组成 连续 排放监督系统。 An important project for radical pollution control is the control of flue gas emissions . Each chimney must be equipped with flue gas analysis instruments and flow meters in order to form a continuous emissions monitoring system. 个显著地功效 ：作为自动化控制系统的检测仪表和丈量物料数目的总量表。 In the process of automatic instruments and devices, flow meters have two significant effects : as an automatic control system detection instrument and a total meter to measure the number of materials. 是 能源计量， 可以 实现节能降耗 的效果 ，进 一步提高 经济效益的重要手段。 The scientific management of energy is an important measure for energy measurement, which can achieve the effect of energy conservation and consumption reduction , and further improve economic benefits. 环保 主题 的凸起，管道运输的特点 开始 引起人们的正视。 With the rising theme of environmental protection , the characteristics of pipeline transportation have caused people to face up to it. 然 管道运输早已有之，但应用并不 是很 普遍。 Although pipeline transportation has existed for a long time, its application is not very common.
而 且品种极其繁杂。 Not only are the number of flowmeters required for scientific experiments, but they are also extremely diverse .
