Abstract

An alternating current meter with photoelectric digital counter structure comprises a metal rotary disk (50), a light-emitting element (60), a photosensing element (70), and a signal line (80). The metal rotary disk (50) is provided in a face plate thereof with a vertical through hole (51). The light-emitting element (60) and the photosensing element are located at the positions corresponding to two opposite rotary disk (50). As the metal rotary disk (50) completes one revolution, one light signal emitted by the light-emitting element is received by the photosensing element (70). The light signal is then converted into a digital signal, which is transmitted to an electronic counter or a remote terminal via the signal line (80).
