Alternating current electricity meter

The induction-type meter is the oldest type of device for the measurement of alternating current consumption. The author of the concept and the owner of its patent of 1889 was the Hungarian inventor, engineer, and electrician Ottó Titusz Bláthy, who worked for the Ganz electrical engineering enterprise. In an induction-type meter, an aluminium disc rotates in the magnetic field generated by two coils connected to electricity, and the moving disc is connected to a drum mechanism allowing readout of indications of the counter, showing the amount of electricity consumed in proportion to the number of rotations completed by the disc. The device presented here was made in the Lviv factory of Towarzystwo Elektryczne Kontakt (TE Kontakt), which was established in 1918. The company produced household electrical appliances.
