ABSTRACT:
A device for reading and transmitting the electrical energy consumption by a user through his telephone line, at predetermined time intervals. Current and voltage sensors provide an analog output that is converted to a digital output and transmitted to a general purpose computer where the necessary energy computations are made. The data is then sent to the central office through an automatic modem at a preselected time when the lines are not congested.
