   Unitariff meters

SEO-1.19.702

PURPOSE AND FIELD OF APPLICATION

    The meters are designed for metering of active electrical energy in two-wire power circuits of alternating current with the frequency of 50Hz as well as for transmission of data to the controller’s office of information and measuring system for registration of electric energy consumption through communication lines.
    The meter has two devices for current measurement – in the phase and null line, what ensures energy metering when current is available  in any connection line.
