FIELD: electric measurement technology. SUBSTANCE: proposed electricity meter has pulse-width and pulse-amplitude modulators, low-pass filter, voltage-to-frequency converter, pulse counter and key added to mix of pulseamplitude modulator. Independence of gain factor of pulse-amplitude modulator from resistance of key in open state is achieved by such approach which contributes to raised accuracy of measurement of electric energy. EFFECT: raised accuracy of measurement of electric energy. 2 dwg
