Abstract
The invention relates to a variable-area flow meter with a measuring tube in which a float provided with at least one permanent magnet and movable by a fluid flowing through the measuring tube is arranged, and with an indicating device arranged outside the measuring tube, said indicating device comprising a magnet holder rotatably mounted about a rotation axis, said magnet holder holding at least one follower magnet that follows the movement of the permanent magnet, and having an indicating element which reflects the movement of the at least one follower magnet, wherein at least one follower magnet in the magnet holder is arranged in such a manner that its magnetic axis is inclined in relation to the rotation axis by an angle (α) not equal to 90°.
