LEAK DETECTION
A water flow detector, the water flow detector comprising a water header tank presence detection module for determining if a water header tank is present in a water system comprising a pipe, the water header tank presence detection module configured to: determine a plurality of pipe temperatures of the pipe based on temperature data received from a first temperature sensor coupled to the water header tank presence detection module, wherein first temperature sensor is in thermal contact with the pipe; determine a plurality of ambient temperatures of the environment around the pipe based on temperature data received from a second temperature sensor coupled to the water header tank presence detection module; determine a plurality of temperature deltas, each of the temperature deltas based on a difference between a pipe temperature of the plurality of pipe temperatures pipe and a corresponding ambient temperature of the plurality of ambient temperatures; detect a start of a period of non-usage of the water system; detect a flow of water in the pipe after the start of the period of non-usage of the water system; analyse a rate of change of the plurality of temperature deltas during the period of non-usage of the water system to detect an interval during which temperature deltas of the plurality of temperature deltas decrease at a rate above a first temperature delta threshold rate; and in response, output a tank indication to a leak detection module, the tank indication indicating that the water system comprises a water header tank.
