Fluid distribution system.

摘要

The invention relates to the field of fluid distribution networks, for example water mains networks. A fluid distribution system comprises a network of conduits and a plurality of valves (4) to control the flow of a fluid through the conduits, and valve keys (18) to control said valves. At least some of the valves are adapted to yield up information on their identity to a valve key, and the information can be transmitted to a central logging station to update a map of valves and their on/off conditions. <IMAGE>
