Abstract
A meter reader for reading a meter have a display portion displaying a total output of a quantity being metered and plural incremental outputs defining the total output. The meter reader includes a sensing mechanism for sensing one of the plural incremental outputs in the meter display portion, and a processing unit coupled to the sensing mechanism for accumulating incremental outputs sensed by the sensing mechanism and for determining accumulated meter output over a time period based on the accumulated incremental outputs. Also included is an output mechanism for outputting the accumulated meter output determined by the processing unit. In one example, the sensing mechanism includes a sensor for sensing only a least significant incremental output in usage included in the meter display portion, and an emitter for illuminating the least significant incremental output included in the meter display portion. Further, the sensing mechanism senses the least significant incremental output included in the meter display portion at least once every full cycle of the least significant incremental output.
