Glass tube rotor flowmeter

Product Features:

Glass tube 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,Glass tube 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 flowmeter. The position height of the float can be used as a measure of flow rate.
