PERFORMANCES OF A CM-SCALE WATER FLOW ENERGY HARVESTER IN REAL ENVIRONMENT FOR AUTONOMOUS FLOWMETERS

The H2020 European project InDeal is an innovative project focused on the development of energy-efficient, eco-friendly and cost effective solutions for district heating and cooling system (DHCS). The project’s goal is to lower energy demand for DHC and to improve systems’ efficiency by creating the tools for better system monitoring what can lower energy losses and reduce bills for the consumers. In the project, CEA developed 2 demonstrators, one water flow energy harvester and one thermal energy harvester. The aims are (i) to make smart flow meters able to work for years without any human intervention by replacing batteries and (ii) to improve the quality and to reduce the costs of water networks monitoring (flowrate, temperature, pressure,leakage detection, pH meters ...).
