M-Bus Wireless Switching Router

Overview：

M-Bus Wireless Switching Router is a meter reading equipment of remote water meter designed according to national standard and is used to obtain the total reading of tap water used on electronic remote water meter. The main function of M-Bus Wireless Switching Router is switch M-Bus signal to wireless signal to communicate with wireless concentrator. It is developed by adopting high performance MCU hardware platform combined with current communication technology. It is especially suitable for centralized meter reading between office buildings where wiring construction is impossible.
