ABSTRACT:
A variable capacitance device generally intended for use in measuring the mass flow of air while passing through an engine-manifold. The device is capable of responding to the impingement of a stream of air on its flexible capacitor plate located within an air conveying duct, in which the impingement tends to bend the flexible capacitor plate over the curved surface of a rigid electrically insulated capacitor plate. The gradual bending of the flexible capacitor plate over the curved surface of the rigid capacitor plate changes the capacitance of the device at rate proportional to the rate of change in the mass-flow of the gas.
