Abstract: An arrangement for generating a digital current measurement signal includes an analog-to-digital (A/D) converter and an impedance circuit. The A/D converter is operable to receive a voltage input signal and generate a digital output signal having a digital value representative of the magnitude of the voltage input signal. The impedance circuit includes at least first and second alternative impedance values and a switch operable to cause the impedance circuit to have a select one of the first impedance value and the second impedance value. The impedance circuit is configured to receive a current signal to be digitized, the impedance circuit generating an output voltage signal representative of the current signal and having a magnitude dependent on the select one of the first impedance value and the second impedance value. The output voltage signal of the impedance circuit is then provided as the voltage input signal of the A/D converter.

Abstract: A metering arrangement includes a meter housing, a source of energy signals, a source of gas flow signals, a source of temperature signals, and a processing circuit. The meter housing is securedly supported proximal to a facility receiving utility commodities. The processing circuit is disposed within the meter housing, and is operably connected to the source of energy signals, the source of gas flow signals, and the source of temperature signals. The processing circuit is operable to generate electrical energy consumption metering information from the energy signals. The processing circuit is further operable to generate corrected gas consumption information based on the received gas flow signals and the received temperature signals.

Abstract: An electricity meter for monitoring electric power consumed from a service line is disclosed. The electricity meter includes a power consumption metering system for measuring the amount of power consumed from the service line, a peripheral device providing a non-critical function, a power converter, and a load management system. The metering system includes a controller and data storage for storing power consumption data. The power converter provides an unregulated voltage output at the terminals of a capacitor for powering the metering system. The load management system selectively couples and decouples the peripheral device from the power converter. The load management system senses the unregulated voltage to determine whether to couple or decouple the peripheral device. A load management system for an electricity meter and a method of managing the loads on the power system of an electricity meter are also disclosed.
