The WT…16… network node is used to receive and handle the data transmitted by 
consumption meters of the Q AMR system. In small plants, one network node suffices 
as a data collector. In larger plants, or when consumption data shall be read out from 
a remote location, an M-bus interface for connection to an OZW10 M-bus central unit 
or a gateway is required. The WTT16... network node is battery-powered, the mains-
powered WTX16... version is available for special applications. 

Use 

The WT…16… network node is a component of the Q AMR system. It has been designed 
for use in buildings to create a radio network for receiving and storing the data transmitted 
by the consumption meters installed in the building. Communication between several net-
work nodes is via radio also so that no wiring is required. All measured values acquired by 
the consumption meters are continuously exchanged within the network, which means that 
every network node stores the current consumption values, the values read out at the end of 
the month, and the set day values of all metering devices on the network. Owing to this 
operating principle, all network data can be read out at any of the nodes, or a QUNDIS gate-
way for remote data transmission can be used with any of the nodes.
