Two-way Residential Gas Metering for Network Continuity

The M125 is the next generation solution in the widely-deployed M120 product line. The module is designed to record and communicate consumption and one channel of interval data. This data equips utilities to develop flexible rate offerings, and assists with capacity planning.

The M125 gas module automatically self-registers on the Gridstream Connect network upon installation, simplifying deployment by eliminating the need for installation, configuration, and specialized tools. The M125 module mounts on almost any residential gas meter built since the 1950’s. In addition, the module can be configured to transmit data in intervals from once a day, to once every hour. The M125 gas module leverages AMI connectivity through other Landis+Gyr products, such as electric meters, routers, street light controllers, or radios on distribution automation devices. This flexibility is key for maximizing the benefits of Gridstream Connect, enabling utilities to effectively manage multiple types of endpoints on a single network.
