摘要: An apparatus including a downhole tool for conveyance in a wellbore extending into a subterranean formation and method of use thereof. The downhole tool may include a turbo-alternator disposed in a passageway for drilling mud, and a controller to: track operating points of the turbo-alternator, determine from the operating points a flow rate of the drilling mud, and control a component of the downhole tool based on the flow rate.
