Glass rotor flowmeterThe main measuring components are a vertically installed lower small upper large conical glass tube and a float that can move up and down inside. When the fluid passes through the conical glass tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the upward force, buoyancy, and viscous lift acting on the float are equal to its gravity, the float is in an equilibrium position. Therefore, flowing throughGlass rotor flowmeterThere is a certain proportional relationship between the fluid flow rate and the rising height of the float, that is, the flow area of the glass rotor flowmeter. The position height of the float can be used as a measure of flow rate.

The application in environmental protection engineering is as follows:

The discharge of smoke, waste liquid, sewage, etc. seriously pollutes the atmosphere and water resources, posing a serious threat to the human living environment. The country has made sustainable development a national policy, and environmental protection will be the biggest issue of the 21st century. To control air and water pollution, it is necessary to strengthen management, and the basis of management is quantitative control of pollution levels.

China is a country that relies mainly on coal as its energy source, with millions of chimneys continuously emitting smoke into the atmosphere. Smoke emission control is an important project for pollution control, and each chimney must be equipped with smoke analysis instruments andGlass rotor flowmeterEstablish a continuous emission monitoring system. The flow rate and volume of flue gas pose significant challenges, including large and irregular chimney sizes, variable gas composition, wide flow velocity ranges, dirt, dust, corrosion, high temperatures, and the absence of straight pipe sections.
