Abstract
A system and method for measuring at least one property of a fluid includes a housing for receiving the fluid, a first and second spaced electrodes positioned in the housing, and an impedance modifier positioned between the first and second electrodes that changes an electrical impedance of the fluid between the electrodes. Electronic circuitry generates different waveform voltages across the electrodes and the fluid, monitors an output thereof to thereby obtain data related to impedance of the fluid for each waveform voltage; and combines data related to the outputs to create a unique identification signature for the fluid. Once signatures for known fluids have been created, they can be compared to a generated signature of an unknown fluid to identify the unknown fluid.
