The object of the project is the design of an intelligent smart meter product for Water Networks. In Greece, the measurement of consumption in Water Networks is carried out mainly with mechanical  meters and the measurements is done with on-site visits, without telemetry, while in some cases the consumption data are sent to the provider by the consumer himself. Internationally there is an established base of short-distance consumption metering networks, where the transponders inform the provider, mainly through Cellular Network telephony, about their consumption and the issuance of bills.

The project proposes the development of an Internet of Things-based intelligent meter management product for IoT consisting of (i) intelligent water consumption and quality meters, (ii) a common low-cost LoRaWAN wireless IoT network and (iii) Artificial Intelligence software for real-time data processing for providers and consumers. The intelligent consumption and quality meters will have a modular design and will consist of 3 distinct subsystems:

  • consumption measurement
  • IoT interconnection
  • quality measurement at both provider and end-consumer level (pH , pipe oxidation, chlorination, hardness and suspended particles)

The individual objectives of the project are:

  1. The development of intelligent consumption and quality meters with modular design that will measure consumption and quality features send data in real time, achieve great energy autonomy and will have a motion sensor in case of movement or vandalism, sensor to detect removal of the battery from the system and mechanism for automatic closing the valve in case of leakage.
  2. The design of an appropriate IoT Network Infrastructure for the collection and transmission of data from intelligent meters to the central infrastructure with the possibility of covering long geographical distances of low energy consumption as well as reliable and secure data transmission.
  3. The design and development of software systems for the management of large volumes of data with the ability to: inform, in real time, about water consumption and quality to users-consumers and stakeholders, of suitability analysis using indicators of demand forecasting quality and change of its quality water distribution in specific activities aimed at raising consumer awareness, and adopting savings practices.
