In Europe we have 20% water loss due to leaking pipes. The average pipeline network is more than 50 years old. With such monitoring, losses become visible. Leakages appear just in time as a warning message on the mobile phone and can be reacted to promptly.
Creeping water losses in flats or hotel facilities can thus also be detected. This is relevant when tenants or hotel guests do not report defective WC flushes, for example. There is enormous potential for savings here.
Another possibility is to trigger alarms when a persistent water consumption is measured although nobody is at home. This “holiday mode” can prevent unpleasant surprises after a relaxing holiday.
