A method is provided for determining and monitoring gas consumption in a gas network under pressure or under vacuum. The gas network may include a sensor(s) capable of recording the state or status of a source(s), consumers, consumer areas or applications. The method includes: a start-up phase, during which the aforementioned sensors are calibrated before use; an optional leak quantification phase, in which unrecorded consumers or leaks are quantified on the basis of measurements from the aforementioned sensors; an operational phase, in which the flow and/or gas volume consumed by each consumer, consumer areas, application or possibly the leak/non-registered consumer is calculated or determined using a cumulative algorithm and a predefined, adjustable time horizon; an output phase, in which the calculated or determined flow and/or gas volume consumed by each consumer, consumer area, application or possibly the leak/non-registered consumer is displayed.

An intelligent electronic device (IED) includes a user authentication module configured for authenticating authorized users of the IED and preventing an access by non-authorized personnel to a user-selectable portion of operational features of the IED. In exemplary embodiments, the user authentication module includes a database of information authenticating an authorized user and a sensor acquiring user-identifying information (e.g., a biometric sensor, a reader of magnetic, holographic, RFID, or smart ID cards, or a keypad). In one application, these techniques are implemented in IEDs such as electrical power and energy meters and used to control access to reset, configuration, billing, communication, and data acquisition/processing functions of the meters.

A system and method for on-location resource consumption monitoring and management including, a sensor attachable to a resource consumption meter monitoring raw resource consumption data outputted by the meter, an on-location network receiving the raw consumption data; a controller interfacing the network for processing the raw consumption data into processed consumption data; and a device linked to the network for displaying the processed consumption data to a user. The network may be linked to a remote server for uploading the processed data, further processing the data, and/or incorporating the data with third party analytical and reporting tools for resource consumption monitoring and management. The system and method may be used for monitoring and managing the resource consumption data of appliances and electronic devices through the use of control modules connected between an electrical supply and an appliance/electronic device.

An intelligent electronic device (IED) includes an image capture module configured for capturing images or video in a location of the IED. The IED may also include a heat sensor for sensing heat inside or outside a housing of the IED.
