Abstract: A personal flow meter for measuring water consumption of an individual has a housing, inductors attached to the exterior of the housing and a rotatable member disposed within the housing. A front cover and rear cover are attached to the housing. The front cover includes a fluid inlet having an angulated internal fluid channel that causes water to enter the housing at an angle. The rear cover has a fluid outlet to allow egress of water within the housing. The rotatable member includes angulated fins. Water entering the housing via the internal fluid channel perpendicularly strikes the fins to initiate rotation of the rotatable member. Magnets are attached to the rotatable member in an alternating magnetic pole arrangement. Rotation of the rotatable member causes the inductors to generate voltage signals. Electronic circuitry processes the voltage signals and generates signals that represents the individual's water consumption over a period of time.
