Description

TECHNICAL FIELD

Embodiments are related to the field of energy metering systems and smart meters.

BACKGROUND

So-called “smart” meters are beginning to replace legacy meters in utility applications. Smart meters can provide a plethora of metering avenues for utilities. The functioning of such meters has been found to offer superior performance and efficiencies than the use of legacy meters.

A smart meter generally records digital electric, water, and/or gas meter consumptions in intervals and communicates information via a communications network (e.g., a wireless communications networks) back to a utility company for monitoring and billing purposes (e.g., telemetering). Smart meters may use wireless technologies for communicating with the utility company. A smart meter can also shut off or suspend the delivery of utility services, under any condition. A smart meter can also facilitate load balancing, emergency shut-offs, and so on, etc.

Conventional metering devices including both legacy and smart meters are not compact. Conventional meters, for example, possess protruding seals and panels, which are not flush. Non-flush panels and protruding elements render the smart meter unsafe for usage. Many of today's energy metering systems including both residential and commercial electric and gas meters are bulky and not convenient to use or integrate with new or existing infrastructure. Mounting pedestals for self-contained meters, for example, are also bulky and costly, and are difficult to integrate with adjoining systems. With the accelerating growth of distributed energy systems and mobile transportation and infrastructure, it would be desirable to provide energy metering systems that can be easily and unobtrusively integrated with the existing utility infrastructure to provide convenient energy delivery, and real time consumption monitoring and transactions.

Accordingly, there is a need for smart meters, which can include flush panels, minimum protruding elements while also being simple to install and use. Furthermore, utility companies desired smart meters that are easy to manufacture. In addition, there is also a desire among utility companies to manufacture smart meters, which are modular, based on layers, and easy to assemble.

The optical port cover 206 can be configured to cover the optical port access 207, the optical port cavity 205 and optical port cover cavity 214, when the dongle 212 is not in use.

The optical port cover 206 can be attached to the outer casing 201, just below the optical port cover cavity 214 through snap joints 215. These snap joints 215 are easy to install and assemble. The locking mechanism 210 can be configured to pass through a cavity 212 provided in the optical port 205, when the optical port cover 206 latches on cover the optical port access 207. The cavity 212 can be configured to house the locking mechanism 210 when the optical port cover 206 is moved pivotally at the snap joints 215 to cover the optical port access 207. Subsequent to the closure of the optical port cover 206, a wire preferably of metal, may be used to lock the optical port cover 206 by inserting the wire in the hole 211 formed in the locking mechanism 210, thus preventing any unauthorized access of the smart meter.

The sealing element along with the securing mechanism 324 may prevent unauthorized access to the function switches underlying the smart meter.

The disclosed embodiments can solve four major shortcomings of existing meters. First, the need to wear conventional seal elements generally present at the sides of the outer surface of the meters is less resistant with respect to theft. Second, the conventional sealing element structure, which can include metal wires wound at the sides of the meters, can lead to serious environmental issues, and also long-term exposure may be hazardous. Lastly, conventional seals are not favorable to digital management and automation.
