Sonic works through a mixture of three different sensors, (ultrasonic sensor, temperature and pressure), it can intelligently analyse water patterns and provide insightful data about water usage. 

HD Ultrasonic measures everyday flow, while pressure testing periodically checks the whole freshwater system for even the tiniest, pin-point leaks and temperature sensing predicts freeze risk before the pipe even bursts.

If it detects a water leak, it'll send a notification through your Sonic mobile App, and if a catastrophic event such as a burst water pipe is to take place, Sonic will shut-off the water supply from the mains and then notify the user.
