Abstract:
The invention comprises a method for obtaining accurate, instantaneous electric consumption data for telemetry purposes from the consumer's utility revenue meter. Heretofore, methods for obtaining high frequency telemetry have been limited to specialized devices which are not based on the utility revenue meter, or are unable to meet the temporal requirements of instantaneous telemetry. The invented method specifically uses external outputs of the utility revenue meter, the pulse outputs or optical reader, acquires and transmits high frequency telemetry in less than 30 seconds inclusive down to 1 second.It is also significant that the invention considers the timing of meter data reads. Other approaches to reading the utility revenue meter focus on pulse counting or use of a predetermined time interval. In the current embodiment of the invention, the device measures the timing of each pulse which led to accuracy within a few seconds.
