Instrumentation and metering are inseparable

On May 20, 1875, 17 plenipotentiaries from 20 countries signed the world-famous "Metric Convention." In 1999, the 21st International Metrology Congress designated the 20th of each year as the "World Measurement Day." After 14 years, measurement has played an indispensable role in economic development, ranging from small-scale inspections to large-scale land surveying and environmental monitoring. Metrology has been rapidly developed and popularized. Industry is inextricably linked.

The "three civilian forms" for water, electricity, and gas in daily life are mandatory measurement instruments for instrumentation of trade settlement. According to the particularity of its use, the state regulations impose a mandatory test before the installation of "three civilian forms" for a limited period of time. Due to rotation. Among them, the use of water meters shall not exceed 6 years, the use of electricity meters shall not exceed 5 years, and the use of gas meters shall not exceed 6 years.

In accordance with the "Measurements Law," taximeters, fuel dispensers, bazaars for trade markets, sphygmomanometers, X-ray machines, CT machines, audiometers used in medical procedures, tonometers and optometry during eyeglass configuration Meters and other measuring instruments shall be subject to periodic verification. Therefore, consumers should pay attention to whether these measuring instruments have undergone mandatory verification when they are in use, and whether they have been affixed with the mark of compulsory inspection by the quality and technical supervision department and are within the validity period.

In industry, the scope of measurement is more extensive. For example, any factory production process is accompanied by changes in the physical or chemical properties of materials. During the period, there must be energy conversion and exchange, and heat exchange is the most common among these energy exchanges. The exchange form. Therefore, in many production processes, the measurement and control of temperature is often an important part of ensuring the normal and safe operation of these reaction processes. Here, temperature-controlled metering and testing instruments play an important role. In addition, the on-site meter measures the pressure, level, and flow of the other three parameters.

Rapid development of measuring instruments and meters

With the improvement of the overall level of China's instrumentation industry, measurement instruments have also achieved tremendous development. According to the data released by the Zhejiang Instrument Industry Association, in 2012, China imported a total of 13,900 gas meters, which was a year-on-year decrease of 21.82% and exported 1,794,600, an increase of 4.96% year-on-year. Imports of water meters reached 23,000, a year-on-year decrease of 4.32% and exports of 2.123 million, an increase of 22.95% year-on-year.

Various metering instrumentation technologies have also made continuous breakthroughs, such as the latest smart meters introduced this year. It is a tool for measuring and charging water, electricity, gas, heat and other energy sources. It is mainly composed of microcomputer chips, embedded programs, and base tables. It controls the work of base tables through the command of embedded programs and the operation of microcomputer chips. The traditional mechanical metering instrument as a base meter is a component of a smart metering instrument. The smart metering instrument integrates a series of technologies such as microelectronics, micro power consumption, remote transmission, sensing, electronic valve control, and automatic control, and becomes a collection of electronic devices. , information, software, communications, electromechanical control and other technologies as one of the products.

Metering Instrument Prospect Forecast

Benefit from the deepening of the promotion of national measurement policies, measurement instruments and meters, especially smart metering instrumentation will have a broad market. According to statistics, in recent years, the growth rate of China's natural gas consumption has been increasing year by year, and the urban gas penetration rate has also increased significantly. By the end of the twelfth five-year period, the number of households using natural gas will increase from 66.2 million in 11 years to 135 million households, a compound annual growth rate of 20%. Thanks to the multifaceted advantages of smart watches, the proportion of new smart gas meters will also increase from 30% to 50%.

IC cards and remote intelligent water meters have been recognized by users such as water companies because they can significantly save user costs. The smart ratio in the future will continue to rise. When the water meter industry only maintains a growth of 10%, the compound water growth rate of the smart meter industry is expected to reach 30% in the next few years. Demand for heat meters Since the country began promoting heat supply in 2010, it began to break out in terms of heat, not area, and it is still at the initial stage of development. The industry has grown rapidly but is fiercely competitive.

In addition, the Ministry of Industry and Information Technology (MIIT) provided opinions on further strengthening the energy-saving and emission reduction work of the non-ferrous metals industry. The opinions pointed out that by the end of 2015, the energy consumption per 10,000 yuan of industrial non-ferrous metals industry will have decreased by about 18% compared with 2010. The total amount of standard coal will be saved by 7.5 million tons, the total amount of sulfur dioxide emissions will be reduced by 10%, and the total amount of pollutants discharged and the concentration of pollutants will be comprehensive. To meet relevant national standards, organize non-ferrous metals companies to carry out energy audits, put forward practical and feasible energy-saving measures and implement them. Strengthen energy statistics work, supervise enterprises to equip instruments and meters and other measurement equipment according to relevant requirements, and industrial measurement instruments and meters will also have great potential.

Measurement Instrumentation Challenge

The basis for China's metrological work is still relatively weak. The second decade of this century is a crucial period for China's building a well-off society in an all-round way and accelerating the socialist modernization drive. It is a crucial period for deepening reform and opening up and accelerating the transformation of economic development. Metrological development faces new opportunities and challenges. Raising the level of measurement and accelerating technological breakthroughs in metering and instrumentation have become important topics.

Accelerate the research of new measurement technologies and test methods such as new sensor technologies and functional safety technologies, speed up conversion and application, and fill gaps in measurement and testing technologies in new areas. Accelerate aerospace, marine monitoring, transportation and other special measurement test technology research, improve the level of professional measurement testing. Improve the level of measurement testing technology in areas such as food safety, drug safety, detection and emergency detection, environmental and climate monitoring, and enhance rapid detection capabilities. Integrate measurement tests into product development, manufacturing, quality improvement, and process control throughout the process to achieve accurate measurement and real-time calibration of critical quantities. Strengthen the core zero-miniature parts and core control technology of instrumentation, and cultivate brand products with core technologies and core competitiveness.
