Abstract:
1. A volumetric fluid flow meter for measuring the accumulated flow, comprising: a housing including a flow inlet port having a connector configured for fastening to a faucet outlet; a flow divider through which the fluid originating from the faucet outlet flows, having a predetermined fraction of the fluid redirected into a measurement compartment that is substantially enclosed by said housing; wherein said measurement compartment forming a container for fluid disposed therein and having a predetermined geometry, so as to provide a representation of the total volume V of fluid having flowed past said flow divider during a predetermined time interval through the relation V=f(s)*s+b, where s represents the fluid level of the fluid contained in said measurement compartment, b is a bias constant and f(s) comprises one of a simple proportionality constant and an arbitrary weighting function, derived from the geometry of said measurement compartment and said flow divider; and a flow outlet port configured to provide an outlet for fluids originating from the faucet.
