  2. Utility submeter - Wikipedia

    en.wikipedia.org/wiki/Utility_submeter

    A submetering system typically includes a "master meter", which is owned by the utility supplying the water, electricity, or gas, with overall usage billed directly to the property owner. The property owner or manager then places their own private meters on individual tenant spaces to determine individual usage levels and bill each tenant for ...

  3. Automatic meter reading - Wikipedia

    en.wikipedia.org/wiki/Automatic_meter_reading

    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 ...

  4. Encoder receiver transmitter - Wikipedia

    en.wikipedia.org/wiki/Encoder_receiver_transmitter

    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 ...

  5. Open metering system - Wikipedia

    en.wikipedia.org/wiki/Open_Metering_System

    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.

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.

  7. Electrical measurements - Wikipedia

    en.wikipedia.org/wiki/Electrical_measurements

    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 ...

  8. IEC 62056 - Wikipedia

    en.wikipedia.org/wiki/IEC_62056

    IEC 61107 or currently IEC 62056-21, was an international standard for a computer protocol to read utility meters. It is designed to operate over any media, including the Internet . A meter sends ASCII (in modes A..D) or HDLC (mode E) data to a nearby hand-held unit (HHU) using a serial port .

  9. Meter-Bus - Wikipedia

    en.wikipedia.org/wiki/Meter-Bus

    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 ...
