Cellular MIU (CMIU™) Pit and Wall Installation and Maintenance Guide 1
Chapter 1: Product Description
This chapter provides a general description of the Neptune Cellular Meter Interface unit
(CMIU™) for wall and pit applications.
The CMIU is a network endpoint that collects meter reading data from an encoder register. It
then transmits the data for collection using 4G LTE cellular technology. The collection data is
stored and downloaded into the utility billing system for processing.
The CMIU is easily installed in wall or pit applications. It operates on AT&T or Verizon 4G LTE
cellular networks. The CMIU stops RF transmissions when the battery discharges below the
normal operating voltage.
