MIRTEK-12-EN-W2

Single-phase multifunctional electricity meter of model MIRTEK-12-EN-W2

The device provides for the metering of the:

  • current time and date;
  • electrical energy quantity on a cumulative total independent of the tariff schedule;
  • electrical energy quantity on a cumulative total and separately by the current tariffs rates;
  • electrical energy quantity on a cumulative total and separately by the current tariffs rates at the beginning of the month;
  • electrical energy quantity on a cumulative total and separately by the current tariffs rates at the beginning of the day;
  • power profile averaged in the 30 minutes interval (or from the following range: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 minutes);
  • electrical energy quantity on a cumulative total and separately by the current tariffs rates at the beginning of the 30 or 60 minutes interval (stated interval of averaging power is 30 or 60 minutes);
  • electrical energy quantity consumed within 30 minutes interval (stated interval of averaging power is 30 minutes).
