Submeters can measure use of a single panel, or multiple points within a panel system using single-point, multi-point, and branch circuit submeters. [9] The latest [clarification needed] trend in submetering is Automatic Meter Reading, or AMR. This technology is used to get from meter reading to billing by an automated electronic means.
Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic ...
Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
North American domestic analog (Ferraris disk) electricity meter. Electricity meter with transparent plastic case (Israel) An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval.
Optical port on a digital kilowatt-hour meter Optical port on a heat meter Optical port on a smart kilowatt-hour meter. IEC 62056 is a set of standards for electricity metering data exchange by International Electrotechnical Commission. The IEC 62056 standards are the international standard versions of the DLMS/COSEM specification.
The open metering system of the Open Metering System Group e.V. stands for a manufacturer- and media-independent standardization for Meter-Bus (M-Bus) based communication between utility meters (electricity, gas, water, thermal energy), submetering (cold/hot water, thermal energy, heat cost allocators), and systems in the field of smart meters.
High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
M-Bus or Meter-Bus is a European standard (EN 13757-2 physical and link layer, EN 13757-3 application layer) for the remote reading of water, gas or electricity meters. M-Bus is also usable for other types of consumption meters, such as heating systems or water meters. The M-Bus interface is made for communication on two wires, making it cost ...
