Byram's smart meters are electronic electricity meters designed to meet residential metering requirements and provide remote communications. As a component of the EnergyAxis® System, our smart meters bring advanced metering infrastructure capabilities to residential metering applications. Utilities can obtain interval data, bidirectional energy, criticaltier, and time-of-use (TOU) data through the EnergyAxis® network. Byram's smart meters are available in most common residential wiring configurations.

The pulse counting transmitter provides the means for tracking pulse meter usage information. The meter generated pulses or switch closures are counted by the transmitter and the data is transmitted periodically to the remote data logger
