FC-706-SC uses real-time reading to communicate with the meter network wirelessly. After the meter network is completed, the water meter command is initiated, and the water meter is connected to the meter system through the star network. After the water meter is connected to the network, the remote master station can real-time read the water meter information. The water meter adopts the intermittent sleep mode to reduce the standby current of the module, and uses a series of mechanisms to reduce the false wake-up of the module by external wireless signals. A certain balance is achieved between real-time performance and low power consumption. After a large number of data tests and actual meter usage tracking, the current real-time reading method is sufficient to meet the actual needs of customers. It is a good solution for remote meter to monitor water meter data in real time.
The FC-706-SC water meter module collects water volume information through photoelectric direct reading devices, and then wirelessly transmits the water volume information to the electric meter. The electric meter reports to the concentrator through the micro-power wireless network, and then to the main station server.
