Encoder/Receiver/Transmitter (ERT) module

A device that attaches to an electricity, gas, or water meter and collects usage and related data either by radio or cellular frequency. An ERT module encodes the data and transmits it to Itron data collection devices and systems such as handheld computers, (HHCs), mobile automated meter reading (MAMR) devices, and fixed networks.

"Module" is capitalized when it is part of the official product name, for example, 500W ERT Module. "Module" is not capitalized when used to generically describe an ERT, for example, "Itron sells Itron ERT modules."
