Application Scope of the Glass FLOW METER

The main measuring element of the glass rotor flow meter is a vertically mounted small upper large cone glass tube and a float movable up and down inside. When the fluid flows bottom-up through the conical glass tube, the pressure difference occurs between the float up and down the float, and the float rises under the differential pressure. When the rising force force, the buoyancy force, and the viscosity lift force are equal to the gravity force of the float, the float is in an equilibrium position. Therefore, there is a cer
