LOW IMPEDANCE ENCODER FOR A UTILITY METER |
摘要 |
A low impedance encoder generally comprises a clock source and a switch. The clock source operates according to a predetermined duty cycle. The switch ha s a first position, closed, and a second position, opened. The duty cycle controls a current flow the switch. A high current flow through the switch indicates that the switch is closed and that the consumption of a utility as registered by the utility meter has occured; the switch will continue to ope n and close throughout the metering process. A low current flow through the switch indicates that the switch is open.
