安装注意事项 Verabar flowmeter installation precautions
1. Measuring liquid: Verabar flowmeter is installed within 160 ° below the pipeline; install gas, Verabar is installed within 160 ° above the pipeline; measuring steam: Verabar is installed below the pipeline; for vertical pipelines, it can be installed around the vertical Install Verabar in any direction of the pipeline 360 °, and choose single or double-sided support according to the pipe diameter and medium. 2. When the straight pipe section upstream and downstream of the pipe is not long enough, install Verabar flow at twice the pipe diameter after the bend. meter. 3. To facilitate cleaning and maintenance of the flowmeter in the future, a bypass pipe should be installed. 4. If there is vibration in the measuring pipe, there should be fixed supports on both sides of the flow meter. 5. The pressure of the pipeline where the flow meter is installed must not exceed the rated maximum working pressure. 6. When the impulse tube leaks, smaller particles in the high pressure balance area of the probe may enter the pressure taking hole. When the pipeline is stopped, small particles may enter the pressure taking tube due to the Brownian motion of the molecule. Clean the probes regularly. 7. Regularly check whether the body of Verabar is bent, deformed, and whether the valve and connection flanges, joints are leaking or blocked. Use iron wire to clear the pressure-receiving pipeline and replace the flange gasket. 8. When measuring gas and steam, the measurement accuracy will be affected by temperature and pressure changes, so compensation should be considered. 9. Each Verabar probe needs to be analyzed for differential pressure, pressure, and structural strength according to fluid conditions before use, and to determine the range of the differential pressure transmitter based on the calculated differential pressure.
。 Recently, it was learned from the International Society of Automation (ISA) that Researcher Yu Haibin of Shenyang Institute of Automation won the "ISAFellow" of the International Society of Automation 2011 for his outstanding contributions to fieldbus technology and will participate in the United States of America The award ceremony at the ISA Honor Awards Annual Meeting held in Massachusetts. The predecessor of ISA is the Instrument Society of America, which was established in 1945. It is a non-profit organization that leads the development of the global instrumentation and automation industry. It helps more than 30,000 members and professionals in the world to solve technical problems and is committed to automation. Development of industry standards. As a Chinese scholar who won this award, the achievement fully affirmed the outstanding contribution of Researcher Yu Haibin in the field bus technology field, and also recognized China's scientific research and standardization work in the high-end technology field. Yu Haibin: PhD in Engineering, currently the Deputy Director, Researcher and PhD Supervisor of Shenyang Institute of Automation, Chinese Academy of Sciences, enjoys government subsidies of the State Council, member of the expert group of advanced manufacturing in the “11th Five-Year Plan” National 863 Program, and review by the National Science and Technology Awards Evaluation Committee expert. ，《自动化学报》、《控制理论与应用》英文版、《仪器仪表学报》编委。 Member of the Technical Committee of IFAC Networked Systems, Member of the Chinese Society of Automation, Member of the Chinese Institute of Instrumentation, Deputy Editor-in-Chief of "Information and Control" Verabar Flowmeter , "Chinese Journal of Automation", "Control Theory and Application" in English, "Journal of Instrumentation" Editorial Board.
