International Classification:

G01D 4/02
G01R 22/06
G01D 4/00
G01R 21/00
H04L 12/28

Abstract:

Embodiments of the invention provide an electric meter assembly including a meter support platform or base able to reversibly electrically couple to a transformer providing inputs including an AC power supply, phase voltage, and/or a phase current. Output of the meter support platform or base can be DC power, AC phase voltage signals and/or AC phase current. Further, a removable or portable meter can couple to the meter support platform or base and to an electric meter system including a meter core coupled to a wireless transmitter, an antenna, an integrated power sensor, and data meter front end. The system includes a data manager configured for electric service analysis including energy usage, and/or interval temperature, phase voltage, current and phase angle in real time, electric energy kWh and kVARh values in a user-specified period, wrong meter base installation detection, physical location of the removable or portable meter, and tamper detection.

International Classification:

G01R 22/06

Abstract:

Some embodiments include a metering system including a base housing configured to be coupled to a supply of a consumable, and including a plurality of meter slots, wherein each meter slot is configured to couple with a removeable meter module. Further, the metering system includes a removeable cover housing configured to removably couple to the base housing, and a meter module that includes at least one meter core and at least one data transfer functionality or assembly. The meter module can independently meter at least a portion of the consumable consumed by at least one consumer. A metering assembly with a removeable meter module and an associated meter slot can independently meter at least a portion of a consumable consumed by at least one consumer, and metering of the consumable to a consumer from one meter slot is independent of metering of the consumable from another meter slot.
