Abstract
An error correction and detection system for a dual-pulse output metering device is provided. The system detects errors in the dual-pulse output of the metering device by comparing the current phase difference it between the pulse streams to a desired or known phase difference and generating an error signal if the current phase difference is different from the desired phase difference. If an error signal is generated, the system additionally accounts for the error and provides a corrected pulse count output by either discarding the extra pulse, or calculating the number of missed pulses, and adding the missing number of pulses to the pulse count output.
