Systems and Methods for Remote Utility Metering and Meter Monitoring
First Claim
1. A method comprising:
- rotating a rotating device by a flow of water;
rotating a drive magnet in response to the rotation of the rotating device, wherein the rotation of the drive magnet generates a time varying magnetic flux density.rotating a registration magnet in response to the time varying magnetic flux density;
rotating a pair of rotors with respect to a series of coils interposed between the pair of rotors, the rotation being in response to the rotation of the registration magnet, thereby generating an alternating current (AC) in the series of coils.

Abstract
A system and method for generating and harvesting energy in response to the flow of water through rotating device, such as a nutating or oscillating disk. Mechanical energy from flow of water is converted into electrical energy via an energy conversion unit. For example, the power generation system may be used to power electronic and mechanical devices used in automated meter reading (AMR) systems. The power generator system may recharge a storage circuit that enables long term AMR operations without the need for battery replacement. The power generation system, in various embodiments, can provide additional power for two-way communication and other sensors such as pressure, temperature, water quality and services such as remote shut-off, event-based messaging, and water quality monitoring.
