The metal tube rotameter mainly consists of a measuring system and an indicator system

The measurement system consists of a metal tapered tube and a rotor that can move up and down inside the tapered tube

The medium flows from bottom to top through the tapered tube, and under the external force of the fluid, the rotor adjusts its position, forming a balance of buoyancy F, thrust P, and rotor gravity G. When G = P + F, the rotor will remain stable in one position

When the rotor stabilizes in one position, the magnetic coupling system drives the pointer, indicating the flow rate on the dial

The position of the rotor inside the measurement system determines the flow rate reading
