Abstract
Utility usage monitoring systems for monitoring the consumption or use of a particular utility and displaying the accumulated use in terms of its cost. The rate of usage of the utility is converted to a pulse train with a repetition rate dependent upon the usage. In one embodiment, a calculator chip having an automatic constant capability and coupled to an electronic display is caused to successively execute a summing operation dependent upon the pulse train repetition rate and to provide a cumulative total for display. A keyboard is provided to enter the automatic constant, and to allow the change thereof to provide the proper utility cost or charge. Another embodiment utilizes a microprocessor coupled to a display for displaying the accumulated utility usage, with the microprocessor being programmed to repetitively update the display. Provisions may be made for entering such parameters as base charges and utility cost break points in accordance with the utility billing practice so as to provide a high degree of accuracy in the accumulated readout. Incorporation of reading and printing devices and a timekeeping capability allows alteration billing rates, billing by mail, time of day (peak hour) rate adjustment and automatic load control and shedding. Various embodiments are disclosed.
