wifi smart energy meter establishes a dual mechanism for data recording and identity verification between the contactless IC card and the IC card, thereby improving the accuracy of statistics and billing. 3 phase energy meter wifi reads user information, recharge status, and historical electricity consumption data from the IC card, compares the current electricity consumption with the card's records, and uses the built-in CPU to complete metering, accumulation, and data storage.
energy meter 3 phase wifi uses an AD converter to collect voltage and current data; smart energy meter 3 phase the internal processing module multiplies and accumulates the sampled values to obtain the user's electricity consumption value.
