Principle structure

As the fluid upward in the tube,the float moves upward to a certain positon where the lifting force and the gravitational force 

are balanced,at the moment,the circulation area between the float and the orifice is kept fixed.the circulation area is 

proportinal to the height of the float, it means the height of the float represent the volumetric flowrate.When the float 

moves up and down,it transmits its positional to the indicator outside in form of magnetic-coupling,so make the needle of the 

indicator follows the movement of the float,and by using the cam board to show the value of flowrate linearly on the indicator
