ã€China Instrument Network Instrumentation Industry】From October 19 to October 21, the Advanced Training Course “On-line Verification/Calibration Methods and Field Operation Demonstration of Water Flow Meters and Modern New Metrology Management Practice†was held by the Training Center of China Academy of Metrology Science. In Kaifeng, Henan Province, the Wuxi Metrology and Testing Center dispatched personnel took part in the training.
Training session
At the training meeting, the teacher taught the development trend of international metrology and the development trend of China's measurement, water flow measurement standard guarantee means and uncertainty analysis, water meter online verification technology method and selection principle, and large-caliber water flow meter verification and on-line calibration methods, etc. The topics were explained in detail and in depth. At the same time, JJG162-2009 Cold Water Meter, CJ/T224-2012 Electronic Remote Water Meter, JJG164-2000 Liquid Flow Standard Device, JJG1030-2007 Ultrasonic Flow Meter and The specifications of JJG1033-2007 “Electromagnetic Flowmeter†were explained.
The participants in this training class are the relevant technical staff of the metrology institutes (institutions) of various provinces and cities, the metrological verification personnel of the National Water Supply Corporation, the national water conservation office, and the relevant personnel of the water conservation monitoring center.
At the training site, related technical personnel and instructors also answered questions and exchanges on the related problems of online flow meter calibration. At the end of the training course, the participants also participated in the demonstration and exchange of on-site operation of the national water flow metering station in Kaifeng, Henan.

Basic Organic Chemicals
Organic compounds in the narrow sense
mainly refer to carbon elements, hydrogen elements, must be carbon-containing
compounds, but do not include carbon oxides and sulfides, carbonic acid,
carbonates, cyanides, thiocyanides, cyanates, carbides, carbon borane,
carbonaceous metals, metal-organic ligand complexes without M-C bonds, some
metal-organic compounds (substances containing M-C bonds) and other
carbon-containing substances mainly studied in inorganic chemistry.
Organic matter is the material basis of
life, and all living organisms contain organic compounds, such as fats, amino
acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc. Metabolism
in living organisms and genetic phenomena in living organisms are related to
the transformation of organic compounds. In addition, many substances that are
closely related to human life, such as oil, natural gas, cotton, dyes, chemical
fibers, plastics, plexiglass, natural and synthetic drugs, etc., are closely
related to organic compounds.
