What Communication Protocols are used in Energy Metering?

Energy meters often feature communication protocols for remote monitoring and integration into energy management systems. Common protocols include:

Modbus (RS485, TCP/IP) which is widely used for industrial automation and monitoring due to reliability and simplicity.

M-Bus which is a common in utility metering for water, gas, and electricity application.

Ethernet/IP which is used for high-speed data transmission in networked environments.

Wireless (based on LoRa, Zigbee, Wi-Fi, GSM/4G/5G) which enables remote monitoring in smart metering applications.

Selecting the right protocol depends on the application, system integration needs, and data transmission requirements.
