ABSTRACT:
Apparatus for measuring the flow of a fluid medium which flows upward through a substantially vertically mounted tube section having a suspended body in the tube section. The vertical position of the suspended body depends on the intensity of the flow. Movement of a magnet, movable with the suspended body, is sensed by a unit which includes a Hall sensor and an electronic evaluation circuit, responsive to the Hall sensor output, develops an output signal corresponding to the flow of the medium.
