  • Dual mode electronic flow control system
    Patent number: 8978688
    Abstract: In various embodiments, two or more electronic flow selectors of an electronic fluid flow control system may be used to control the flow rates of multiple fluids. In a total flow control mode, a first electronic flow selector may be used to select a total flow rate of two or more fluids. A second electronic flow selector may be used to select a flow rate or ratio of a flow rate of one fluid to the total flow rate of the two or more fluids. In a direct flow control mode, each electronic flow selector may be used to select a flow rate of a unique fluid. One of the fluids may be oxygen, and the other fluid, a balance gas, may be selected as either nitrous oxide or air using an electronic balance gas selector.
