Electromagnetic flowmeter model
Electromagnetic flowmeter is widely used in industrial production, national defense construction, scientific research and export trade, as well as in all walks of life.In the production of petroleum industry, from the extraction, transportation, refining and processing of petroleum to the sale of trade market, flow measurement is centered on the process, and flow measurement is indispensable for every stage. Otherwise, normal production and trade of petroleum industry cannot be guaranteed.In the petrochemical industry, inaccurate flow measurement will lead to the imbalance of component distribution ratio, unable to ensure product quality, and more serious production safety accidents.
In the electric power engineering industry, the measurement and adjustment of the flow of liquid, vapor, vapor and other substances play a key role.The accuracy of flow measurement is not only of great practical significance in economic development to ensure the operation of power stations under the main parameters, but also has become a key step to ensure the safe operation of power stations with the development trend of ultra-high pressure large-space generating sets.
If the instantaneous rate of water supply and drainage flow of large space heating furnace is cut off or reduced, it will lead to more serious accident of hot pot or burst tube.This stipulates that the flow measurement equipment should not only ensure accurate metrological verification, but also immediately send out the alarm system.In the steel industry, the flow measurement of cooling circulating water and co2(or gas) during the whole process of iron making is one of the key parameters to ensure the product quality.In light industry, food, textiles and other manufacturing industries, are also indispensable flow measurement.
The ultrasonic transducer that USES more is outside clip type and plug type.Monophonic ultrasonic flowmeter is simple and easy to use, but this kind of flowmeter has poor adaptability to thermal convection state diffusion transformation. The rapid development of electronic information technology and electronic information technology greatly promotes the upgrade of the instrument panel, and the flowmeter keeps springing up.So far, it is known that there are thousands of flowmeters looking to the sales market, and many of the difficulties in field application are expected to be addressed.It is relatively late in the technical work of flow measurement in modern times in China. It is set at the upper and lower end of the flow safety channel 6 and relative to hole 11 and 12, so as to reduce the measured hydrodynamic injection hole 11 and 12.Measurement control system 19 for measuring ultrasonic wave propagation time between ultrasonic transducer 8 and 9;And measuring component 20, which is used to measure the flow according to the data signal of the measuring control system 19.
The flow meter can meet the needs of most markets, including water, oil, food, lubricating oil, chemistry, cosmetics, ink, pharmaceutical, coating, petroleum, automobile, glue, polyurethane, electrolyte and additives.
