Abstract
The method involves passing the coins (9) through the air gap of a U-shaped ferrite core (15) associated with the edge of the conveyor path (5) with a coil (14) subjected to an AC voltage. The coin diameter are derived from the return flux of the magnetic field at the immersion depth associated with each coin. An Independent claim is also included for an arrangement for implementing the method.
