1. A telemetering system for electrical power consumption by individual users who previously have been supplied with a conventional meter of the type comprising a disk whose revolutions are correlated with consumption, the meter having at least one mark thereon, the system comprising:

  • (a) a pulse generator for each meter comprising;

    (i) at least one optical sensor capable of detecting the passage of the mark during rotation of the disk and of sending a detection signal;

    (ii) a circuit for detecting the detection signal;

    (iii) a revolution preselector in which the number of revolutions of the disk is preset and corresponds to a predetermined quantity of power;

    (iv) a frequency divider which is connected tothe revolution preselector and to the circuit for detecting the detection signal and which receives and meters the detection signal and sends a consumption signal to a line adaptor when the value of the signal from the detection signal corresponds to the quantity of power present in the revolution preselector;

    (v) the line adaptor sending the consumption signal to;

    (b) a meter concentrator comprising a connection bus which connects together;

    (i) at least one analog/digital converter block which receives the consumption signals from more than one pulse generator;

    (ii) a microprocessor with its program memory;

    (iii) duplicated non-volatile memory means;

    (iv) means for external communication having at least one series line, said series line being connected to;

    (c) reading means comprising a connection bus which connects together;

    (i) a microprocessor with its program memory;

    (ii) duplicated non-volatile memory means;

    (iii) clock means;

    (iv) first means for communicating with a central computer, which means receives the signals from at least two meter concentrators;

    (v) a second means for communication between the reading means and external peripherals.
