Abstract
The present invention provides for a self-powered fluid meter that uses the kinetic energy of a fluid being measured to provide power for circuitry that may perform functions related to the fluid measurement. An element is placed within a rotating magnetic field created from the kinetic energy of a fluid. This element creates an electrical pulse to power the circuitry.
