Abstract
A metering system can include a pull up circuit to be selectively coupled between a voltage node and a metering line that communicates a signal indicative of status of a flow line through which a metered substance flows. An impedance of the pull up circuit is set to reduce power consumption based on a calibration, and the pull up circuit can be disabled between sampling of the signal to reduce power consumption.
