Compact Mini Mobile Interrogator (CMMI)


 The CMMI is a radio frequency transmitter and receiver that use the Global Positioning System (GPS) to keep track of its location during the collection of meter readings.  Unique signals are sent from the CMMI to each meter requesting specific information from that meter; other meters hearing the request will ignore the commands.  By selective retrieval of data and management of the communications process, mobile meter reading can typically be accomplished at posted driving speeds.Readings collected by the CMMI are stored for later communication to the utility Customer Information System for billing and service applications.
