MeterBus

MeterBus is a communication protocol designed for the remote reading of utility meters, such as those used for water, gas, and electricity. Developed by the Meter-Bus User Association, it is widely used in Europe and other regions. The protocol operates over a simple two-wire bus system, allowing for efficient and cost-effective data transmission between meters and a central collection point.

MeterBus supports various types of meters, including cold and hot water meters, gas meters, and electricity meters. It uses a master-slave architecture, where a central unit (master) communicates with multiple meters (slaves) to collect data. The protocol is designed to be robust and reliable, with features such as error detection and correction to ensure accurate data transmission.

One of the key advantages of MeterBus is its simplicity and low cost. The two-wire bus system reduces the need for complex wiring, making installation easier and more affordable. Additionally, MeterBus supports both synchronous and asynchronous communication, allowing for flexible data collection schedules.

The protocol is standardized under the EN 13757 series of European standards, which define the physical and data link layers. MeterBus also supports various application layers, allowing for the transmission of different types of data, such as meter readings, diagnostic information, and configuration settings.

In summary, MeterBus is a versatile and cost-effective communication protocol for remote meter reading, widely used in utility management systems. Its simplicity, robustness, and flexibility make it a popular choice for utility providers and meter manufacturers alike.
