ABSTRACT:
An improved flowmeter is disclosed which comprises a fixed magnetic ring at one end of a cylindrical tube and a second magnetic ring disposed within the tube adapted to slide freely therein, and being moved by the fluid to be measured. The opposing magnets exert a repulsive force on one another which is balanced by the fluid flow; the position of the movable magnet provides an indication of the quantity of flow.
