Fiscal Metrology

SL7000 – Smart Industrial Polyphase Electricity Meter

Fiscal electricity meter for commercial and industrial customers.

Electricity

Overview & Applications

The Itron SL7000 is a high-performance polyphase electricity meter engineered for fiscal measurement in MV/HV substations, commercial and industrial connections, and power generation plants. With Class C and Class B MID approval, and Class 0.2s accuracy, it delivers complete application versatility across direct connection up to 120 A, semi-direct, and indirect (CT/VT) configurations.

Equipped with advanced multi-tariff calculations, bi-directional 4-quadrant measurement, high-capacity non-volatile memory for simultaneous load profile curves, and power quality event logging.

Supports native DLMS/COSEM communication across dual independent serial communication ports (RS-232 and RS-485) alongside front optical interface.
