Abstract
Fluid regulation may be achieved by a process performed by a controller. The process may include regulating a first fluid with a fluid-driven fluid regulator, receiving a second fluid, receiving electric power generated using the second fluid, and controlling the fluid regulator with the second fluid. The process may also include determining whether wirelessly sent instructions regarding regulation have been received and, if wirelessly sent instructions regarding regulation have been received, adjusting control of the fluid regulator.
