Radio frequency automated meter reading device

A device for connecting to a meter, comprising:

• an interface module adapted to coupled to said meter having a rotating disk, said interface having an optical transmitter directing optical energy to the rotating disk, the interface module sensing a rotating marker on said disk and generating a first signal indicating the direction of disk rotation;
• a controller receiving said first signal, said controller generating a data signal indicative of a measured quantity and generating profile data;
• a wireless transmitter, responsively coupled to said controller, modulating said data signal and transmitting said modulated data signal at a fixed predetermined RF frequency at a user selectable first predetermined time interval adapted to reduce interference without requiring external polling;
• a profile module that obtains and stores the profile data at profile time intervals being substantially longer than the first predetermined time interval, wherein the device is operable from an internal power source;
• and
• an output port for outputting profile data to a reading unit.
