Glass Tube Rotameter is basically a variable area flow meter.

　　The working principle of the Glass Tube Rotameter is that the area of ​​the fluid in the glass tube is variable. The main function of the Glass Tube Rotameter is to lift the float in the tapping tube. Therefore, the area through which the fluid passes increases. As the float moves up and down according to the flow rate of the fluid in the tube. Therefore, the combination of the tube and the float determines the fluid flow rate indicated on the scale.
