Abstract: A system for determining at least one property of a fluid and ensuring measuring surfaces of the system in contact with the fluid remain free of contaminants, includes a housing within which at least one measuring surface is located. The fluid to be measured flows through the housing and contacts the measuring surface. A signal generating device operably associated with the surface provides signals indicative of the at least one fluid property. A transducer is operably associated with the housing and causes agitation of the fluid flowing through the housing so that the measuring surface can be cleaned even during fluid measurement.

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.
