The CMe3100 is an M-Bus Metering Gateway for Fixed Networks, capable of reading up to 512 meters. It compiles meter data into customized reports and delivers it to receiving systems via fixed networks. Compatible with all M-Bus standard protocol meters and Elvaco’s CMe/CMeX Series, it supports various integration protocols such as ModBus, DLMS, JSON, and REST. With real-time data delivery and flexible licensing, it offers cost-effective customization and functionality extension. Its robust polyamide casing ensures longevity, and it’s easily mountable on a DIN rail. LED indicators provide status updates, and a push button allows for easy device reset.
The CMe3100 M-Bus Metering Gateway is a first-class solution for remote meter reading. Depending on the product version, the device can read up to 512 meters that use M-Bus standard protocol and can connect to a fixed network, providing a comprehensive meter reading solution. Once recorded, the meter data is compiled in customised reports according to predefined rules and then delivered to a receiving system in real time.
