When fluid flows from bottom to top in the cone tube, the pressure difference in float up and down, to float up, when the pressure difference and float gravity, buoyancy and viscous force in the force balance, float in a stationary position, when the flow changes, through the cone tube, and change of float ring gap between fluid flow, float up and down the pressure difference of the corresponding change, float to move up and down, so the height of the float rest position can be used as a measure of the flow. _x000D_ _x000D_ Product Photos _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
