Industrial electric furnace glass rotor flowmeter

The glass rotor flowmeter is a variable area flowmeter, and the main measuring components of the glass rotor flowmeter are a vertically installed lower small and 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, there is a certain functional relationship between the fluid flow rate flowing through the glass rotor flowmeter and the rising height of the float, that is, the flow area of the glass rotor flowmeter. The height position of the float can be used as a flow measurement indication. Suitable for measuring the flow rate of single-phase non pulsating fluids (liquids or gases).

Glass rotor flow meters are widely used in the industrial furnace industry due to their low cost, intuitive readings, easy installation and maintenance, and ability to achieve certain measurement accuracy. They are widely used in carburizing furnace flow meters, nitriding furnace flow meters, nitriding furnaces, converters, drum furnaces, carbon nitrogen co diffusion furnaces, mesh belt furnaces, and gas atmosphere furnaces. They can also be specially manufactured for users.
