Abstract:
    The single ring coded directly reading radio teletransmitting water meter includes one reformed mechanical meter as basic meter to provide direct reading function, one low power consumption radio teletransmitting module as the data treating and transmission unit, and one directly reading electronic emitting device comprising three parts of infrared emitting tube, single ring semi-circular coding holes on the character wheels of the basic meter and infrared receiving code tubes and providing electronic directly reading function. The digital code is acquired from the character wheels with the emitting device, treated in the radio teletransmitting module and uploaded to the managing computer while the command from the managing computer is received. The radio teletransmitting module is powered with lithium cells, and radio communication is completed in the network communication protocol ZigBee and frequency 2.4 GHz.
