Abstract
The disclosed sensors convert flow of liquid along a passage into electrical signals to represent rate or volume of the liquid flow. Vanes of a rotor are driven by the liquid so as to sweep past plural excitation and sensing electrodes that pass current through the liquid and sense the changing impedance caused by the vanes. The impedance of the liquid portion of the sensor circuit is modified at a frequency representing the travel of rotor vanes past the electrodes.
