Description
Documentation

Electricity meters of the WQR type are designed to measure and indicate energy in one- and three-phase networks. A microprocessor equipped with a 7-digit electro-mechanical counter monitors the counters and holds the readings in the event of an electrical breakdown.

Types of WQR meters:

WQR96 7-digit meter with one pulse output for measuring only one type of energy (kWh or kvarh).
WQ2R96 Two 7-digit counters and two pulse outputs for measuring two types of energy (kWh and kvarh of consumed and delivered energy).
WQR96-x 7-digit meter with one pulse output for energy measurement (kWh or kvarh) and 90-degree scale for simultaneous display of instantaneous power value (active or reactive).
WQR96-c 7-digit meter with one pulse output for energy measurement (kWh or kvarh) on a 240-degree scale for simultaneous indication of instantaneous power value (active or reactive).
