Abstract
The present invention is a metering system including a signal conditioning circuit, processor and output system. The signal conditioning circuit receives a state-indicating signal and responsively produces a repetitive digital signal compatible with the processor. The processor samples the repetitive digital signal, determines the period thereof and produces an output signal having a value related to the state-indicating signal. The output system displays the value of the output signal.
