Smart metering is a term used for intelligent energy management and metering systems for residential and commercial communities. These systems are not only cabable of measuring and managing electricity, but can also be applied to water metering.
Absolute energy's smart metering system can control up to two circuits on the end-user's distribution board. Typically these would be the high usage appliances, such as a geyser and/or pool pump. A data concentrator is used to manage to control each individual metering unit via power line transmission. Up to 2000 distribution boards can be controlled from one data concentrator. Each data concentrator connects to the Internet via GPRS. The entire system can be managed from a web-based control interface.
Absolute energy's user interface device is similar to a cordless remote. Touch PadThis allows end users the comfort and convenience of controlling and managing their electricity expenditure. Options also exist whereby users can manage their electrical devices via mobile phone.
Automated meter reading uses wireless or other technology to record how much electricity is being used by a consumer and then transmit the recorded data to a central point where billing can be carried out. Automated meter reading is also applied to certain meters which contain a short range wireless transmitter that meter-readers can receive and manually record the consumption. Here, we discuss the former definition. Automated Meter Reading is being implemented by several municipalities, including Johannesburg City Power.
The meters are radio controlled from a central location or hub and broadcast their readings via radio in the 433MHz UHF band. The results are entered into a central computer database and software is used to manipulate the readings so that the user is billed with the correct tariff amount.
