Abstract
Abstract A device for metering the flow of two fluids, such as the flow of liquid fluid and air to an internal combustion engine, includes a respective duct for each of the two fluids, an ionic flow meter in each of the two ducts, a valve controlling the flow of one of the fluids through its duct and circuitry comparing the flow rates measured by the ionic flow meters and controlling the valve accordingly so as to maintain a desired ratio between the two flow rates.
