Intelligent utility meter system
An intelligent utility meter system installation is described for measuring A.C. electric energy having repetitive A.C. cycles, comprising: (1) an ''outside'' principal meter unit including: (a) means for sampling current and voltage and for calculating power consumption at least 300 times per second; the sampling occurring asynchronously and not in any fixed time relationship with respect to the A.C. electricity cycles; (b) the outside unit further including means for determining the total kilowatt hours used, and the present billing status; and (c) alphanumeric display means for displaying power being used, total kilowatt hours and present billing status; (2) a remote ''inside'' unit including: (a) alphanumeric means for displaying the information displayed by the ''outside'' unit; (b) means for selectively retaining a desired continuously updated display; and (c) means for reading a credit card and automatically changing the billing status information within the intelligent utility meter as credit card information is read; and (3) the system including means for determining both the magnitude and direction of the electric power passing through the meter system.
