wetnet true monitoring of water networks
TRANSCRIPT
WETNET is a Consortium created to realize a Project Co-Foundedby the Eco-innovation initiative of the European Union, to developea new low cost technology for metering water flow and pressure, combined with an OPEN SOURCE Supervisory Software, to intercept and cut water leaks, reducing energy costs in water networks.
