µPORT 3G/W M-Bus

Data concentrator

A small device with big capabilities. Thanks to its Wireless M-Bus interface, this product is perfectly suited for collecting data from water, gas and heat meters and transmitting it to meter reading systems or to an FTP server. Additional RS-485 and RS-232 interfaces expand its functionality to include support for electricity meters and various types of controllers.
