Abstract
A radio frequency automated meter reading (AMR) device for determining quantities of a consumed utility product including electric, gas and water service. The present invention intermittently transmits utility product consumption as a modulated RF signal, and does not require complex polling and bi-directional communication. Data is obtained and formatted for transmission and is adapted to be received by a remote receiving device having an RF receiver. The present invention is adaptable to water meters, gas meters and electric meters, and has an IR programming module facilitating remote programming and diagnostic procedures. In the case of water and gas meters, an internal lithium battery provides an operational life of up to ten years. In the case of the electric meter, power is tapped directly from the electric service.
