  • Patent number: 4041376
    Abstract: This invention relates to a detector for detecting the state of electrically non-conductive or substantially electrically non-conductive fluid, such as its flowing velocity, direction, composition or pressure, comprising a transducer to generate an electric signal responsive to said state of said fluid, said transducer having at least one ionizing area exposed to said fluid and said electric signal appearing as variation in conductance across said ionizing area, an amplifier to amplify said electric signal from said transducer, having a high input impedance and a low output impedance, and means to shield said transducer and said amplifier.
