Fluid characterization apparatus,systems,and methods

摘要

An apparatus and method may operate to position an electrode assembly within a fluid. The electrode assembly may include an injection electrode and a receiving electrode in spaced relation to one another. The method may include providing a series of excitation signals at a plurality of frequencies to the injection electrode to inject a series of injection signals into the fluid. The method can further include receiving signals in response to the series of injection signals through the receiving electrode. The received signals can be representative of an impedance spectrum including impedance values representative of the fluid. The method can further include generating a phase angle fingerprint based on the impedance spectrum to characterize the fluid according to the phase angle fingerprint. Additional apparatus, systems, and methods are disclosed.
