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 ...
A WMBUS Gateway (Wireless M-Bus Gateway) is a communication device that enables remote reading of water meters by bridging the gap between the water meters equipped with Wireless M-Bus communication modules and centralized data collection systems. The gateway typically operates on standard frequencies such as 868 MHz (Europe) or other ISM bands ...
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 ...
Itron, a spinoff of Spokane-based Avista Corp., formerly Washington Water Power Co., was founded in 1977 in Hauser Lake, Idaho when a small group of engineers wanted to build a more efficient way to read utility meters. [7] [8] In 1984, Itron experienced global expansion into the Asian market and developed new manufacturing plants in France and ...
The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1] [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.

Mueller Systems was founded in 1859 as Hawes and Hersey Company in Boston, Massachusetts and was a manufacturer of bolts, rotary pumps, and other machinery. [3] [4] In 1885, the company received a patent on the rotary displacement meter and began manufacturing water meters under the name Hersey Meter Company, offering its first rotary and disc meters for sale in 1886.
