               Future development of flow meters (1)
          Flow is an important parameter in the modern industrial measurement process. Humans have a long history of measuring fluids.
     From the ancient Romans measuring the water flow of residents, the ancient Egyptians measuring the water flow of the river to the modern people's measurement of various industrial process flows, they have fully systemed human infinite wisdom.
世纪随着能源计量、环境保护、交通运输等应用领域对流量测量需求的牵引,使得流量计得到快速发展。 In the 20th century, with the application of energy measurement, environmental protection, transportation and other applications to the demand for flow measurement, the flowmeter developed rapidly. In particular, the rapid development of microelectronics technology has provided a variety of new components for the flowmeter manufacturing technology, which has further promoted the development of flowmeters from mechanical to intelligent and modular. The development and application of new technologies, new devices, new materials, new processes and new software have made the measurement accuracy of flowmeters higher and higher, and the range of flow measurement has become wider and wider.
At the same time, the requirements of flowmeters for measuring media are decreasing, the scope of application is becoming wider and wider, and the degree of intelligence and reliability have been greatly improved. Jiangsu Jinhu Dongxiang Instrument Co., Ltd. uses high-tech non-standard high-tech enterprises to develop instruments, and a large number of microelectronic computing technologies.
流量计的分类有多种方法,如可按测量原理分类,也可按仪表功能分类及结构类型分类等等。 Flowmeter classification and principle: There are many ways to classify the flowmeter. For example, it can be classified according to the measurement principle, but also according to the instrument function classification and structure type classification. This article explains the principles and characteristics of various flowmeters one by one.
近几年来,从我国工业发展的需要出发,国内流量计的使用随着经济的发展,工业应用增长较快,行业协会提供的 2003 年及 2005 年统计数据分析可知, 03 年与 05 年各种流量计的市场需求有较大的增长,其中以差压变送器为最大,其次是浮子流量计。 Distribution of domestic flow meter market: In recent years, starting from the needs of China's industrial development, the use of domestic flow meters has grown rapidly with the development of the economy and industrial applications. Analysis of statistical data provided by industry associations in 2003 and 2005 shows In 2003 and 2005 , the market demand for various flowmeters increased greatly. Among them, differential pressure transmitters were the largest, followed by float flowmeters.
15% 以上。 In recent years, the overall annual growth rate of flow meters has been more than 15% .
  Development trend of flow meters: With the development of modern industry, it is necessary to gradually improve its performance, and technological progress has also made it possible to improve the flow meter. The development of the flowmeter will develop to improve the reliability of the flowmeter, improve the adaptability of the flowmeter to the medium and the environment. At the same time, with the application of new signal processing technology and new signal transmission technology, the flowmeter will develop in a highly intelligent direction.
