The main function of the smart meter system is to transport the volume consumption value to main data base unit (server or main computer) through some repeating points.

   The system included these elements: The flow sensor, the valve (DC solenoid valve), the transceiver, the controller, the LCD, Vent valve

   Each home or factory connected to smart meter and these meters relay the data to sub stations through any appropriate method these methods could be : Wired method Cables. RF communication methods (AM and FM), GSM network Wi-Fi connection, Ethernet network. Then the substation carries the data to main station, and the master computer does bill processing while no manipulation attempt, the substation will read the consumption and then convert it to m3. Also the authority can easily control the service so they could cut the service out by sending the stopping code to the meter.

    The benefits of smart metering for the utility accurate meter reading, no more estimates, improved billing, accurate profile, true costs applied and Improved security efficient procedure. We have achieved the goal of research; It can be used efficiently in Lima Company.
