Abstract
A universal fluid flow sensor system and method installable in a toilet tank. A system is disclosed that includes a housing that contains a power source and an event processing system; a flow sensor coupled to a base of the housing, wherein the flow sensor provides flow rate data to the event processing system, the flow sensor having an inlet adapted to receive an inflow of water from a fill tube and an outlet adapted to expel an outflow; a universal stem that extends from the housing and includes at least two different mounting systems adapted to seat the housing onto different overflow tube types, wherein the universal stem includes an elbow assembly configured to receive and redirect the outflow into an overflow tube; and a pair of cylindrical probes positioned in parallel within the elbow assembly, wherein the probes activate the event processing system in response to a detection of water contacting the probes.
