The document describes WETNET, a consortium created through an EU eco-innovation initiative to develop a new, low-cost technology for monitoring water flow and pressure. The technology includes pulse flow meters and sample flow meters, data loggers, and open source supervisory software. This system is intended to help detect and reduce water leaks in distribution networks to lower costs and conserve resources.

1. Sottotitolo

2. WETNET is a Consortium created to realize a Project Co-Founded
by the Eco-innovation initiative of the European Union, to develope
a 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.
