Flume is an American company founded after California's 2014 drought to make household water use visible. Its single product line is the Flume smart water monitor, a strap-on sensor that reads the existing residential water meter magnetically and relays usage to a Wi-Fi bridge indoors, so it needs no plumbing work. The app reports real-time consumption by fixture, sets budgets, and sends leak alerts for both catastrophic bursts and slow drips.
