The RBVT Series Vortex Flow Meter Applications:
- Energy Measurement: Energy into primary energy (coal, crude oil,coal bed methane, LPG and natural gas), secondary energy (electricity, coke,artificial gas, refined oil, liquefied petroleum gas, steam) and energycarriers working fluid (air, oxygen, nitrogen, hydrogen, water);
- Industrial Production: Widely are used in metallurgy, electricpower, coal, chemical, petroleum, transportation, construction, textile, food,medicine, agriculture, environmental protection and people's daily life, andother fields of national economy, the development of industrial andagricultural production, energy conservation, improve product quality animportant tool to improve economic efficiency and management level plays animportant role in the national economy.
- Environmental Protection: Flue gas emissions, waste, sewage andother heavily polluted air and water, a serious threat to the humanenvironment. National sustainable development as a national policy,environmental protection will be the biggest problem of the 21st century.Pollution of air and water to be brought under control, we must strengthenmanagement, and infrastructure management is a quantitative amount of pollutioncontrol.
- Transportation: There are five ways: Railway road, air, water,and pipeline transport. Wherein the pipeline transport, although it has longbeen, but the application is not common. With the outstanding environmentalissues, pipeline transport characteristics attracted people's attention.Pipelines must be equipped with the meter, it is the control, allocation andscheduling eyes, is also not safe and economic accounting supervisor essentialtool.
