Abstract
A corona discharge gas flow transducer includes a high tension discharge electrode, and a receiving electrode having two terminals, the difference between the current flow from these terminals representing the gas mass flow. For deriving a current difference signal there is a circuit comprising a current to voltage converter, switch means alternately connecting the two terminals to the converter, and further switch means a.c. coupled to the converter and operable in synchronism with the switch means. The transducer is used in an i.c. engine fuel system in which the transducer output is integrated over a fixed engine crankshaft angle to generate a fuel demand signal.
