Abstract
A flow meter comprises a housing with a tube, a floater inside the tube, and a permanent magnet embracing the housing. The volume of a fluid being passed through the tube defines the height of the floater position in the tube. The floater is equipped with a rotation coil and bulb connected thereto. Rotating the floater in the magnetic field of the permanent magnet under the influence of a fluid induces a voltage in the coil, and the bulb is turned on making reading volume values easier and more convenient.
