Product Description
 Overview
The meter is the hi-tech mechatronics product, using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and control the close/open of the valve, and is also able to transfer the data to the back-office system(data center) after reading the meters by a wireless handset reader.

System Operation Principle
The structure diagram of the whole system is as follows, the server send the commands to the data concentrator through the network, further, the concentrator transforms the received commands into the wireless signal and send the signal to the water meters; The water meters respond and execute the actions accordingly, after receiving the commands; The meters deliver the result or data back to the data center as per the original route after the actions finished.
