Abstract: A mass flow air meter for use in a mass air flow type electronic fuel injection system for an engine to measure mass air flow through an air induction system including a scheduled area valve consisting of a butterfly valve cooperating with scheduled valve throat area openings whereby the pressure drop in the induction passage through this valve is held approximately constant during changes in fluid flow by allowing the valve throat area openings to vary.
