Advanced Metering Infrastructure is made up of four basic parts, according to the U.S. EPA: Metres, A Metre Interface Unit (MIU), Additional Sensors, And Remotely Controlled Variables. The MIU receives a hardwired signal from the metre, converts this signal to a flow value, stores this flow value, and then wirelessly transmits the data to the information management system. Meters monitor the flow to a customer connection. Most metres are solid-state or mechanical metres.
These metres frequently work in conjunction with other sensor types, such as pressure, temperature, sound, and water quality monitors. The information management system receives the data, which is also occasionally incorporated into the utility's SCADA system. With the help of the information management system, a utility can remotely turn off or on water service at a customer connection.
