AEM Contor Monofazat 2-Fire

The AEM Contor Monofazat is an electromechanical single-phase electricity meter designed for residential energy monitoring. This specific model, the CMA M4, is manufactured by AEM (Aparate Electronice de Măsură), a prominent industrial manufacturer based in Timișoara, Romania. The device features a classic rotating disk mechanism with an analog mechanical register to track kilowatt-hour (kWh) consumption.

AEM has a long history in the Romanian industrial sector, originally established as a state factory before transitioning to a private entity. The brand is a major supplier for Romanian utility companies like Electrica S.A., which is also identified on the meter's faceplate. Today, the company remains a key player in the European energy measurement market, producing a wide range of smart and analog meters for gas and electricity.
