At present, many remote rural areas has long been adopted the way of flat rate in using water, the characteristics of this pattern is that no matter what the monthly consumption of the user's water use, as long as they pay a certain amount of charges. Water consumption is serious inconsistent with water charge, which is not conducive to water supply department to regulate the consumption of water use, and is adverse to the environmental protection and water conservation. The location of rural areas is dispersed, and considering the current mobile network is widely covered, we can use GPRS network of China mobile and China Unicom to build a wireless automatic meter reading system in the laboratory. The results show that the application of GPRS technology in rural water monitoring system, on the one hand, can reduce burden of traditional manual meter reading; On the other hand, the measurement data are accurate, which completely overcomes the drawback of manual meter reading.
